BUFO. 259 
to B. simus of Schmidt, as this author describes his species with an abdomen “ fere 
glabrum,” whilst our examples have it distinctly granulated. However, fortunately, 
the Natural History Museum has received, through Dr. Werner, one of the type- 
specimens of Schmidt’s Bufo simus; it is only 17 millim. long, but has a distinctly 
granulated abdomen. 
Bufo simus is closely related to B. intermedius (Giinth.), from which it differs only in 
having the tympanum hidden under a tubercular skin. The specimens from Omilteme 
and Amula have a particularly rough skin on the upper parts of the body, as well as 
on the lower.

The projecting ridges of the head are rather feebly developed; the supraciliary, 
convergent in front, terminate behind in a fork with short prongs. Interorbital space 
concave, and, in the middle of its length, rather broader than the supraocular cover. 
Snout short, with distinct, short, convergent canthi, and with the sides slightly sloping. 
Tympanum not covered by tubercular skin, though rather small, one-third or one-half 
the area of the eye. Parotoids of moderate size, prominent, elongate elliptical, longer 
than, and as wide as, the supraocular cover, immediately behind the hind margin of the 
orbit. Upper parts with small, flat, not densely packed, tubercles, which do not extend 
on to the interorbital space ; a lateral series of somewhat more conical tubercles; lower 
parts finely granulated. First finger longer than second ; toes two-thirds webbed; two 
metatarsal tubercles, of which the inner is somewhat compressed ; a very fine serrature 
takes the place of a tarsal fold. Gyreyish or greenish, marbled with darker ; lower parts 
uniform whitish.

This is the only Central-American specimen which I have found to agree with 
B. intermedius in the distinctness of the tympanum and the comparatively smooth 
texture of the skin. The form B. siémus is much more common and more widely 
spread; and I therefore conclude that the specimens named B. intermedius by Cope 
and Dugés belong to B. stmus rather than to the present form.
