distance between vent and heel. Disks of the fingers large, truncated, much larger 
than those of the toes; first finger rather longer than second; fingers free; toes one- 
fourth or nearly one-third webbed. Metatarsals without pads; a single metatarsal 
tubercle ; a tarsal fold. Brown above, the upper part of the snout of a lighter colour ; 
sides of the body, anterior portion of the hind limbs and the posterior portion of the 
calves marbled with black and yellow; hinder part of the thighs with small yellow

I hesitate to identify this frog with Z. ragulosa, as the form of its snout and the 
extent of the web are differently described and represented by Keferstein. Hylodes 
raniformis from Colombia (Bouleng, Ann. & Mag. N. H. 1896, xvii. p. 19) is much 
more nearly allied to, and perhaps identical with, it. The extent of the web between 
the toes is about the same in both H. guentheri and H. raniformis. 
The specimen from the Rio Ceibo agrees singularly well with the figure given by 
Keferstein, only the tuberosities on the back are much smaller and indistinct; it is 
quite intermediate between Keferstein’s example and the types.of H. raniformis.

Habit not slender. Snout rather obtuse, with the canthus rostralis-not very sharp, 
and with sloping sides. Eye equal to its distance from the nostril.. Tympanum round, 
two-fifths or three-fifths the size of the eye in females. Upper parts, and still more 
the sides, with small tubercles or short folds of the skin:. an adult female has the sides 
of the abdomen extensively granular. Length of the body (distance of vent from snout) 
equal to the distance between vent and heel. Disks of fingers and toes small. The 
two inner fingers equal in length. Toes barely one-fourth webbed. Two metatarsal 
tubercles, of which the outer is very small and may be entirely absent; a tarsal fold. 
Brownish-olive or dark brown, marbled with darker colour, generally a lighter 
interorbital cross-band ; hinder part of the thighs spotted with white. Lower parts 
white, throat often marbled with brown.
