63. CERBERUS RHYNCHOPS, Schn. 
Homalopsis rhynchops, Cantor, p. 94. 
Cerberus rhynchops, Boul. Cat. Snakes, ili. p. 16. 
Cantor mentions this species from the “ Malay Peninsula and 
Islands,” and there are specimens in the British Museum from 
Penang from him, and from Singapore from Dr. Dennys. Stoliczka 
found it in the collection he got from Penang and Province 
Wellesley. 
This appears to be a common species. I obtained one specimen 
from Tanglin, Singapore, six from Changi, Singapore (sea-water), 
and three from Linga Island (sea-water). Seven of these had 23 
rows of scales, and three 25 rows; the ventrals varied from 139 to 
150 and the subcaudals from 54 to 64; they varied in length from 
470 to 670 mm. 
Both Homalopsis and Cerberus seem sluggish on land, and gentle 
when handled. 
Hab. India, Ceylon, Burma, Indo-China, Malay Peninsula and 
Archipelago, and the Pelew Islands.

Homalopsis leucobalia, Cantor, p. 102.

the collection he got from Penang and Province Wellesley.
