- Closely allied to the preceding, the only structural difference 
being that the vertebral scales are not so large, mostly longer than 
broad, the largest never broader than long. Ventrals 220-237; 
subcaudals 122-146. Pale brown above, head with dark brown, 
black-edged spots or symmetrical markings; forty to sixty dark 
brown black-edged large transverse spots on the body, the anterior 
extending right across down to the ventrals, the others confined to 
the back and accompanied on each side by a smaller spot; lower 
parts yellowish, dotted or powdered with dark brown. 
- Total length 810 millim.; tail 240.

Agrees in structure, and particularly in the largest vertebral 
scales being broader than’ long, with H. cenchoa, but differs in 
having only 15 rows of scales. Dorsal spots terminating in an 
angle near the ventrals ; no lateral spots. 
Total length 622 millim. ; tail 189.

Rostral small, broader than deep, scarcely visible from above; 
internasals much shorter than the prefrontals; frontal once and
