It is impossible to give precise boundaries to the Milky Way, the visible local arm of our galaxy; as best as I can figure, it now crosses the ecliptic at approximately 22 Gem to 8 Can, 15-23 Sag, & 29 Sag to 9 Cap (tropical). This means that there are two degree areas, at about 22-23 tGem-Sag, & 29 tGem-Sag thru 8 tCan-Cap, that have the Milky Way at both ends, and form an axis).

Machina Electrica (27 Psc-15 Ari) was created Bode in 1800 & placed in his atlas "Uranographia" in 1801; it was south of the center of Cetus, between Fornax & Sculptor, & represented an electrostatic generator. It is no longer included in star maps.
Frederici Honores (3-21 Ari) was created by Bode in 1787 next to Lacerta, out of stars between Andromeda, Cepheus, Cassiopeia and Cygnus: lambda (18AR01), chi, 10TAU13, iota (15AR48), psi (19AR40) Andromedae, to honor Frederick II of Prussia: "Below a nimbus the sign of royal dignity hangs, wreathed with the imperishable laurel of fame, a sword, pen and and olive branch, to distinguish this ever to be remembered monarch, as hero, sage, and peacemaker." Before that, in 1679, Royer had placed the Sceptre & the Hand of Justice in the same area, to honor King Louis XIV. They are no longer used.
Psalterium Georgianum, or Harpa Georgii, George's Harp (obsolete), was created beneath the forefeet of Taurus by astronomer Maximilian Hell in 1789 to honor George III of England; it spans approx 21Tau-0Gem.
Triangulum Minor was formed by Hevelius just south of Triangulum, in the same longitudes; it is obsolete.
Musca Borealis The Northern Fly, near Triangulum & just above *Aries; first appeared on a globe by Plancius in 1613 --he called it Apes, the Bee. In 1624 Bartsch changed it to Vespa, the Wasp; bugged by all this, in 1687 Hevelius put it in his atlas as Musca, the Fly. (And a patriotic Frenchman named Pardies tried, in 1674, to use the same stars for "Lilium", a fleur-de-lis). It is no longer used, but if you are itching to swat the critter, its stars were what are now 33, 35, 39 & 41 Arietis, i.e. about 16-18 tTau. (Another Musca of the southern skies is still used - see below). Just east of Horologium was Solarium, the Sun Dial, an obscure and no-longer-used figure.
Custos Messium, the Harvest-Keeper, was introduced by de Lalande in 1779, above Cassiopeia, near the north celestial pole, about where Cameleopardus, the Giraffe, is now. It is no longer used so it is difficult to define. As far as I can tell, it would run from about 15 Aries to 17 Gemini (1980).
Tarandus or Rangifer, the Reindeer: Le Monnier put Rangifer on his 1743 star map; it spans approx. t14 Tau - 2 Can. (No longer used).
Sceptrum Brandenburgicum, the Brandenburg Sceptre: placed in a chart in 1688 by Gottfried Kirch. It consists of 4 dim stars immediately to the west of Lepus, tropical longitude about 3-7 Gem, 1980. No longer used. Do not confuse with the Sceptre and Hand of Justice, Chapter 1.
Telescopium Herschelii: Herschel's Telescope: This abandoned figure was formed by the Abbé Maximilian Hell of Vienna in 1789, to honor Sir William Herschel, placed in the general area of Uranus' discovery. Originally it was in two parts: Tubus Herschelii Major & Tubus Herschelii Minor, but Bode in 1800 reduced it to one ("Major"). It ran from just above the heads of the twins, thru the lower part of Lynx, to Auriga's whip arm; its main stars were theta, omicron and 70 Gem, 16 Lynxis, & 63, 64, 65, 66 & psi6 Auriga, + a few others; it ranged from about 8 to 24 tCan. (Allen gives a slightly different span, from the psi stars of Auriga (4-9 Can) to pi Geminorum (22CNC25). Do not confuse this with Telescopium, which is still in use & resides in tCapricorn.
Gallus, the Cock or Cockerel (obsolete) was formed by Dutch theologian Petrus Plancius in 1613 (Allen says it was formed by Bartsch, but Ridpath is the more reliable source); it lay in the Milky Way, in what is now the northern part of Puppis, behind the back of Canis Major. In the same area as Gallus, Officina Typographica, the Printing Shop, was formed by Bode in 1801. The span of both Gallus & Officina Typographica runs from approximately 25Can to 12Leo (1980). Neither figure is used today.
A vague & obsolete figure called Jordanus, the River Jordan started at Cor Caroli, ran under the Bears above Leo, Cancer, and Gemini, thru stars of Leo Minor and the Lynx, ending at Cameleopardus; according to Allen, it was formed by Bartschius; according to Ridpath, by Plancius.
Lochium Funis, the (nautical) Log and Line (obsolete) was formed in what are now stars of northern Puppis by Bode in his atlas of 1801; it lay just to the east of Pyxis, the Compass (originally the Mast) of Argo Navis. Its span was about 5Vir to 22Vir, though the line itself was pictured above the compass, starting at about 7Leo.
Felis, the Cat (obsolete) : Joseph de La Lande created a cat out of very dim stars in Hydra and published it in 1805; it is no longer used, but I have tried to track it down , so that you may curl up with the critter, & purr.; span: approx. 1-20 Vir.
Robur Carolinum, Charles' Oak: The alpha star of Robur is/was Miaplacidus, beta Carina (Argo's keel), at 1Sco42; it is hard to tell what the other stars were, but some of the probables are: kappa Velorum (Markeb-28Vir37); R Velorum, 4Lib37; iota Carinae, 5Lib03; phi Velorum, 5Lib40; mu Velorum, 10Lib14; AG Carinae (var) 10Lib58, RR Carinae (var) 12Lib21; upsilon & P Carinae, 22Lib36 & 47; theta Carinae, 28Lib55; omega Carinae, 7Sco10.
Mons Maenalis appeared in the 1687 star atlas of Hevelius, representing a mountain in Arcadia in Greece; it was shown w/ Böotes pictured standing upon it; it runs approximately through the 2nd half of tLibra & the 1st decanate of tScorpio (no longer used).
Quadrans Muralis, the Mural Quadrant, just to the north of Böotes ("between the right foot of Hercules, the left hand of Böotes, and Draco") was invented by Lalande in 1795. Although no longer recognized, a famous meteor stream that radiates from this area on Jan 2nd and 3rd is still called the Quadrantids.
Two other minor obsolete figures overlapping one another were also in tScorpio: Le Monnier created the Solitaire in 1776, perched on the tip of the Hydra's tail just under the Scales, made up of pi, 50, 51, 52, 58, 59, 60 Hydrae (8Sco13, 9Sco48, 12Sco11, 13Sco51, 18Sco05, 19Sco47, 20Sco39, 20Sco17 ranging from 7 to 13 south latitude) & some stars of Centaurus; it represented an extinct flightless bird, similar to the Dodo, but the illustration was of a rock thrush known as the Solitaire of the Philippines; English scientist Thomas Young renamed it the Mocking Bird on his star map of 1806; then an unknown illustrator changed it to Noctua, the Night Owl. English astronomer John Flamsteed called Solitaire "The Hermit Bird."
Poniatowski's Bull: formed in 1777 by Abbé Poczobut, of Vilna to honor, King Stanislas (Poniatowski) II of Poland. He used a V-shaped set of stars mentioned in Ptolemy's Almagest as just outside of Ophiuchus (betw Ophiuchus & Aquila) which the Abbé thought resembled the V-shape of Taurus' Hyades. In 1613, 1½ centuries earlier, these stars, with those of Vulpecula had been combined by Petrus Plancius to form the River Tigris, (introduced at the same time as Jordanus, the River Jordan. Tigris ran from beta & gamma (Ophiuchus' rt shoulder), on between Aquila & Hercules' left hand, & then between Albireo (ß Cygni) & Sagitta to Equuleus & the front of Pegasus, ending at the horse's neck.
Cerberus, the Hound of Hell: Cerberus, the triple-headed Hound of Hell (Hesiod said 50-headed), was sometimes figured in Hercules' left hand; it runs from about 29 tSag to 7-8 tCap; no longer on star maps, it was, at times, combined with Ramo, the Branch, an Apple Branch in Hercules' hand.
Globus Aerostaticus, The Balloon: (no longer used), appeared in Bode's atlas in 1801; it had been suggested by de Lalande to honor the Montgolfier Brothers. It was placed under Capricornus, at the eastern part of Microscopium, betw the tail of Piscis Australis & Capricorn's body. It ran (roughly) from about 28 Cap - 15 Aqu.
