the eyes; frontal broader than the rostral, but little longer than the diameter of the 

 eye, in contact with the prefrontal and the ocular; prefrontal in contact with 

 frontal, ocular, and subocular; no preoculars; a subocular; eye under the posterior 

 and lower part of the ocular; four upper labials, the first the largest, second and 

 third in contact with the subocular, the second also in contact with the upper 

 nasal, which reaches the subocular. Twenty-two scale-rows around the body; 

 diameter of body contained forty-five times in the length. Tail shorter than 

 broad, ending in a point, but without spine. 



Brown, each scale darker in the center; a little lighter beneath. Tip of head 

 lighter with fine brown markings. 



This species resembles H. albirostris Peters more closely than any other. It 

 is distinguished by having one, instead of two suboculars, by the position of the 

 eye under the ocular shield, and by the second upper abial being separated from 

 the prefrontal by the nasal.
