Mr. G. A. Boulenger on a new Batrachian. 185 
Mr. R. R. Mole submitted to me three specimens obtained 
from Bromelias in Trinidad by his friend Capt. F. W. Urich, 
I at once thought of Amphodus, and this guess at the genus 
was confirmed on opening the mouth of the frog, which 
showed large widely spaced teeth in the lower jaw, decreasing 
in size from the symphysis, and small teeth on the para- 
sphenoid bone. This little frog, measuring only 32 mm. from 
snout to vent, is specifically different from 4. wucherert, the 
tympanum being completely hidden ; but as it agrees tolerably 
well with the rather unsatisfactory description and figure of 
Hyla aurata, Wied *, from Bahia, stated to live in the same 
surroundings as /. luteola, I am disposed to refer it, provi- 
sionally at least, to the species so named, on account of the 
golden-yellow colour of the three stripes on the back. Should, 
however, Hyla aurata, Wied, prove to be a Hyla, the name 
Amphodus auratus, Blgr., would nevertheless stand for the 
Trinidad frog. 
Capt. Urich intends to give an account of the habits of this 
frog, as observed by him, and in the meantime he has 
requested me to draw up a definition of the species. 
Amphodus auratus. 
Head much depressed, a little broader than long; snout 
truncate, as long as the orbit, with distinct canthus and 
nearly vertical loreal region; nostril near the tip of the snout ; 
interorbital space broader than the upper eyelid; tympanum 
hidden ; a strong ridge above the temple. Fingers and toes 
moderately long, the tips dilated into well-developed disks, 
the subarticular tubercles very feeble ; fingers free, first 
shorter than second; toes slightly webbed at the base. The 
tibio-tarsal articulation reaches the eye ; tibia half the length 
of head and body, longer than the foot. Skin smooth, coarsely 
granular on the belly and under the thighs. Brown above, 
with three golden-yellow longitudinal streaks on the back, 
the outer bifurcating on the head, the branches ending 
between and behind the upper eyelids ; or head yellow, with 
brown spots and three brown streaks, the outer following the 
-canthus rostralis and the supratemporal ridge. 
The three specimens described were obtained on Mount 
Tucutche, a little above 3000 feet altitude.
