Mr. G. A. Boulenger on a new Batrachian. 185 



'to 



Mr. R. R. Mole submitted to me three specimens obtained 

 from Bromelias in Trinidad by his friend Capt, F. W. Urich, 

 I at once tiiouglit of Amphodus, and this guess at the genus 

 was confirmed on opening the mouth of the frog, whicli 

 showed large widely spaced teeth in the lower jaw, decreasing 

 in size from the sympliysis, and small teeth on the para- 

 sphenoid bone. Tliis little frog, measuring only 32 mm. from 

 snout to vent, is specifically ditferent from A. ivucheren\ 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 H. 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, 

 liowever, Hyla aurata, Wied, prove to be a Hyla, the name 

 AmpJwdus 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 raucb 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 tiian 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.
