In Edmund Halley's southern catalogue (_Catalogus stellarum australium_), published in 1679 and incorporated in Flamsteed's _Historia coelestis_ (1725), the following constellations are named:--Piscis australis, Columba Noachi, Argo navis, Robur Caroli, Ara, Corona australis, Grus, Phoenix, Pavo, Apus or Avis Indica, Musca apis, Chameleon, Triangulum australe, Piscis volans, Dorado or Xiphias, Toucan or Anser Americanus, and Hydrus. Flamsteed's maps also contained Mons Menelai. This list contains nothing new except Robur Caroli, since Columba Noachi (Noah's dove) had been raised to the skies by Bartschius in 1624. The constellation Robur Caroli and also the star Cor Caroli ([alpha] Canum Venaticorum) were named by Halley in honour of Charles II. of England. In 1690 two posthumous works of Johann Hevelius (1611-1687), the _Firmamentum sobiescianum_ and _Prodromus astronomiae_, added several new constellations to the list, viz. Canes venatici (the Greyhounds), Lacerta (the Lizard), Leo minor (Little Lion), Lynx, Sextans Uraniae, Scutum or Clypeus Sobieskii (the shield of Sobieski), Vulpecula et Anser (Fox and Goose), Cerberus, Camelopardus (Giraffe), and Monoceros (Unicorn); the last two were originally due to Jacobus Bartschius. In 1679 Augustine Royer introduced the most interesting of the constellations of the southern hemisphere, the Crux australis or Southern Cross. He also suggested Nubes major, Nubes minor, and Lilium, and re-named Canes venatici the river Jordan, and Vulpecula et Anser the river Tigris, but these innovations met with no approval. The Magellanic clouds, a collection of nebulae, stars and star-clusters in the neighbourhood of the south pole, were so named by Hevelius in honour of the navigator Ferdinand Magellan.
