Camelus sentence example
Dr Leche also institutes a comparison between the skeletons of the wild and the tame Bactrian camel with the remains of certain fossil Asiatic camels, namely, Camelus knoblochi from Sarepta, Russia, and C. alutensis from the Aluta valley, Rumania.

On the under side of the free edge of the mantle are situated the numerous small cutaneous glands which, in the large A plysia camelus (not in other species), form the purple secretion which was known to s the ancients.

The skull generally resembles that of Camelus, the relatively larger brain-cavity and orbits and less developed cranial ridges being due to its smaller size.
Possibly this Russian camel (Procamelus khersonensis), as it is called, may form the connecting link between the typical Procamelus of North America and the fossil camel (Camelus sivalensis) of the Siwalik Hills of India.
