Schlegel, Phys. Serp. 502, states that Hoogli Pattee, Russell, 
Ind. Serp. t. 10 (Hydrophis Schistosus, Daud. Rept. vii. 386; Pe- 
lamis Schistosus, Merrem, 139; Leioselasma Schistosa, Fitz. Isis, 
1827, 737), is a half-grown specimen of this species ; but this is in- 
consistent with Russell’s description and figure of the head shields. 
6. Hypropuis. 
Head moderate, rather short: nasal shield moderate, four-sided, 
truncated, or slightly notched in front: rostral shield broad, short, 
five-sided, three-toothed below: labial shields large, occupying 
more than half the front of the lips; the first upper square, mode- 
rate ; the second, third and fourth large, the fourth under the eye (or 
sometimes divided into two shields under the eye): the four or five 
lower labial shields large, band-like; the rest small, triangular ; 
there are sometimes some small triangular scales on the edge of the 
lower lips above the other shields: lower rostral shield triangular: 
temple shielded: scales of the body with a central keel (less distinct 
in the young specimens); of the belly broader; of the neck longer,
