Formerly, the lower southern sky in winter was occupied by a gigantic constellation "Argo Navis", the Argonauts' ship. The constellation had a span of over 70 degrees in east-west direction, and was the largest asterism in the heavens exceeding Hydra, which is presently the largest one. In the mid-18th century, Lacaille divided the older constellation into four smaller constellations: Carina, Pyxis, Vela, and Puppis.
The constellation of Puppis represents the Stern of the Argo Navis. You can find it just southeast of Canis Major as a large and a bit warped square formed by 2nd or 3rd magnitudes. Puppis crosses the meridian at fairly lower sky in Japan, it might need clear sky to recognize the entire constellation.
