Cope.} 98 [July 20, 1877. 
below 43; forty-five transverse rows between nape and origin of tail, and 
thirty-six rows between front of humerus and vent. 
The interfrontonasal is transversely diamond-shaped, and has no exter- 
nal plates at its lateral margins. The frontonasals have considerable 
mutual contact. There are two postnasals; the anterior (and only) 
canthal descends to the labials, taking the place of the loreal, and there is 
one large preocular. A postmental follows the symphyseal, and then one 
pair of infralabials in contact. Two pairs follow, the anterior interrupted 
by one, the second by two, scales. The auricular opening is nearly as 
Jong as the fissure of the eye. The appressed limbs are svparated by the 
space of four ventral cross-rows, or the length of the longest digit of the 
manus. The tail is of moderate length. 
Color of upper surface and sides, brown, the latter a little darker, and 
bounded above by a narrow black line. A somewhat irregular row of 
small black spots down the median dorsal line. Below yellowish olive, 
the scales of the abdomen with black borders, those of the gular and 
thoracic regions with black centres. 
Total length, M. .148; length to auricular meatus, .012; to axilla, .028 ; 
to vent, .061.

ern Cordillera of Costa Rica ; W. M. Gabb. 
This species I provisionally identified with the G. fuluus of Bocourt, 
which has been found in Guatemala. The two species are probably nearly 
allied, but present a difference in the cephalic scutellation, which is of 
generic value.
