Description.—Body rather stout, with short tail. Head 
broad, short, depressed, but little distinct from neck. Snout 
acute and turned upward at tip. Rostral plate acute, 
produced forward and upward, its upper surface concave, 
recurved on top of snout, separating the internasals widely, 
and broadly in contact with prefrontals. Internasals very 
small, Anterior nasal merged with first labial. Posterior 
nasal merged with anterior, or distinct. No loreal, pre- 
frontal in contact with second labial. Frontal, supraocular 
and parietal plates normal. One preocular. Two post- 
oculars. Temporals one followed by two, or 2+3. Supra- 
labials seven, third and fourth reaching eye. Inferior labials 
seven to nine, fourth usually largest, the first pair meeting 
on median line. One or two pairs of genials, posterior very 
small when present. Scales on body smooth, broad, in 17 
or 19 rows. Anal divided. Gastrosteges varying in number 
from 129 to 146. Urosteges in two series of from 28 to 36. 
The color above is light brownish gray crossed by a 
series of transverse brown bands or blotches. These blotches 
may be edged with black. They may extend down to 
the gastrosteges, becoming narrower on the sides, and may 
tend to divide into a dorsal and two lateral series of spots 
anteriorly. On the middle of the body a series of lateral 
bars may alternate with the dorsal ones. The brown dorsal 
blotches between head and anus vary from 31 to 40. There 
are eight or nine similar transverse spots on the tail. The 
first blotch on the neck is large and is extended forward 
medially to the parietals. The head is olive gray with a 
broad brown band across the parietals and including the tip 
of the frontal. A second band extends between the eyes
