From the collections of 1872. 



I have long been familiar with this small and brightly-colored species, 

 and have generally supposed it to be the young of the B. microscapkus, Cope. 

 The reception of larger specimens enables me to learn that it differs from 

 that species in many respects, among which may be mentioned the general 

 reduction of the auditory apparatus. The species in this point and in style 

 of coloration resembles the Ollotis coerulescens, Cope, from Costa Eica. 



The plate exhibits a view of the dorsum and abdomen of the species.
