brachials slightly larger, postbrachials distinctly larger than those 
of this species; the largest of the outer tibials is larger than that of 
A. plew, and also much wider; in A. pileit the width of this scale is 
about twice that of the adjacent scale proximally, while in A. garmani 
the two plates are about equal; upper side of the wrist covered with 
scales rather irregularly arranged; about thirty scales in the fifteenth 
ring from the base. 
Coloration:— Lighter in color than A. plewi, with numerous pale, 
blue-gray or straw-color spots posteriorly, giving the legs the appear- 
ance of being gray reticulated with brown instead of brown with gray 
spots as in A. plew; the heavy blotching extending down the tail, the 
spots being often bordered anteriorly with a zigzag rim of dark brown. 
Remarks:— The relationship of this form to A. plezz is so close that a 
detailed description is not necessary. The description was made of 
an adult male that measured one hundred and twenty-six millimeters 
from snout to vent. Only one example seen.

Rostral forming an acute angle behind; nostril between the two 
nasals; anterior pair of nasals just in contact behind rostral; fronto- 
nasal longer than wide in contact with the loreal; prefrontals broadly 
in contact; frontal in contact with the first supraocular posteriorly, 
with the second supraocular anteriorly, the posterior half separated 
by a single row of granules; a pair of frontoparietals separated from 
the third supraocular by one to four rows of granules, five occipitals, 
the three median in a transverse row and slightly anterior to the outer 
two; nine supraciliaries, the posterior four small; four supraoculars, 
the posterior smallest and followed by a large granule, the first sepa- 
rated from the loreal; three posterior supraoculars separated from the 
supraciliaries by a double row of granules ending anteriorly in a large 
granule; last supraocular separated from the outer occipitals by four 
or five rows of granules; six and seven supralabials; six infralabials; 
between infralabials and chin-shields a wedge of one or two rows of 
granules extending anteriorly to the first chin-shield; chin and throat 
covered with minute granules, a band of slightly larger ones extending 
across the middle, the median ones and two groups slightly anterior
