The three examples which I have referred to this species are Mexican, and come 
from one of our editor’s collectors; unfortunately, the writing on the label has been 
effaced, so that collector and locality are unknown. It seems to me probable that the 
Central-American specimens named Bufo sternosignatus by Keferstein and Cope were, 
in fact, the present species. 
I had determined our specimens as Bufo marmoreus (Wiegm.) when I received, 
on loan, the types of Bufo lateralis, Werner, and B. argillaceus, Cope, by comparison 
of which the identity of these toads was ascertained. I am greatly indebted to 
Dr. Franz Werner and the authorities of the National Museum at Washington for 
their kindness in communicating these examples. Our figure is taken from the type 
of B. lateralis.
