I have not seen Central-American examples of this species, and therefore have 
taken the above notes from the Venezuelan types in the British Museum. I doubt 
whether the Central-American toads named B. sternosignatus by Keferstein and Cope 
were in reality this species. 
Boulenger was right in referring to B. valliceps the young specimens which I had 
regarded as belonging to B. sternosignatus.

A raised ridge above and behind the eye, without parietal branch; interorbital 
space concave, as wide as the supraocular cover. Snout rather contracted and pointed, 
with angular curved canthus rostralis. Tympanum distinct, about half the area of the 
eye. Parotoid elongate, much longer than, but scarcely as wide as, the supraocular 
cover. Upper parts covered with warts and glands of unequal size; a fold or series 
of tubercles from the parotoid to the groin. Lower parts finely granular. First toe a 
little longer than the second. Toes half-webbed ; two small metatarsal tubercles, the 
outer one very small. A tarsal fold is replaced by a series of tubercles. Light greyish 
or brownish, with a pale vertebral line, dividing two rows of large blackish-brown, 
more or less ocellated, symmetrical markings: the foremost is the interocular band, 
the two sides of which form an open, obtuse-angular VY.
