A stout species, covered above with prominent, rough, wart-like tuber- 
cles, and with a circle of the same around the eyes; four or five of 
those above the eyes are larger and more prominent. Body thick, broad- 
ovate, swollen beneath, moderately convex above, obtusely rounded 
posteriorly. 
Male: Head as broad as the body, whole upper surface of body and 
head to base of arms covered with prominent and persistent, unequal 
warts, which are roughened by sharp conical papille, eight or ten on 
the larger warts, but only two or three on the smaller ones; the warts 
diminish in size anteriorly, and on the sides, before they disappear; 
around the eyes they form irregular circles; just above each of the eyes 
there are two much larger ones, bearing more than twenty conical pa- 
pille; there is one before and one behind these, of somewhat smaller 
size. Hyes large, the lower lid purple and thickened, overlapping the 
upper one, which is thin and whitish. ‘a 
Arms considerably longer than the head and body, not very stout, 
compressed, bearing a single crowded row of large whitish suckers,
