Puppis is a Southern Hemisphere constellation otherwise known as the Stern. It was originally part of the Greek constellation Argo Navis but was divided into three separate constellations (Carina, Puppis, and Vela) by Abbe Nicolas Louis de Lacaille (Wikipedia) in the 1750s and published posthumously in Coelum Australe Stelliferum in 1763. Puppis remains one of the 88 modern constellations defined by the International Astronomical Union (Wikipedia).

Puppis (abbrev. = Pup; genitive = Puppis) covers 673 square degrees or 1.63% of the celestial sphere making it the 20th largest constellation. It contains 237 stars brighter than apparent magnitude 6.5, the brightest star being Naos.
