Hab. Nicaraeua (Cope); Costa Rica (Brit. Mus.) ; Panama, Chagres (B. & G.). 
Abdominal scutes in ten longitudinal series; none of the scales on the throat are 
conspicuous for their size, but they increase somewhat in size in the posterior rows; a 
broad band of granular scales separates them from the scales of the collar-fold, which 
are rather small, in three or more series. Nostril between two scutes; supraorbitals 
four. Humeral scutes in about three longitudinal series. 
The coloration of this species varies greatly, not only according to the locality, but 
also with age and individually. Thus the British Museum possesses specimens from 
Costa Rica 6 inches long (without tail), which agree entirely in coloration with the figure 
given by Girard of a specimen from Chagres (C. presignis). Another specimen, which is 
figured on Pl. XIX., from the same locality, and was obtained with the others, but 
* This synonymy is not intended to include the binomial names of all the varieties (real or supposed) of 
this widely-spread species, which have been introduced chiefly by American authors, but only such as, like 
“presignis,’ have been intended for Central-American specimens. 
t I am indebted to the kindness of Prof. Pagenstecher and Dr. Fischer for the opportunity of comparing one 
of the types with our specimens.
