BATRACHIANS.

 (Plate 5. fi-s. 3-6.) 



1. Oreophhynella Quelchii, Blgr. (Plate 5. fig. 3.) 



This tiny toad was described by me as the tyi)e ol' a new genus in 189") (Ann. & Mag. 

 N. H. [6] xvi. pp. 125 & 522) from specimens collected on the; suiimiit of Mt. 

 Roraima by Messrs. Quelch and McCoimell. Numerous specimens liave since been 

 obtained at the same altitude (8500-8000 feet). 



I have now the pleasiu-e of describing a second species of the same genus, from the 

 base of the mountain. 



2. Oreophrynella Macconnelli, sp. n. (Plate 5. fig. 4.) 



Closely allied to 0. Qaelchii, but distinguished by the more prominent snout, projecting 

 much beyond the mouth, and by the greater distal expansion of the digits, which end 

 in distinct truncated disks. Interoi-lntal space broader than the upper eyelid. First 

 toe mucli longer than second, as long as fourth ; no distinct subarticular or metatarsal 

 tubercles ; the first and second toes appear to be opposable to the I'ourth and fifth, both 

 fascicles being bound by the thick integument, and the third toe, which is the shortest, 

 being free between them. The tarso- metatarsal articulation reaches the; eye. Upper 

 parts covered with small, smooth, feebly pronainent warts ; lower parts with flat 

 granules. Olive-brown above, with lighter marblings, and a series of small yellowisli 

 spots, forming a line on each side of the back from the eye to the groin, continued 

 obliquely across the upper surface of the femur ; upper lip yellowish, with two dark 

 brown bars below the eye ; lower parts whitish. 



From snout to vent 22 millim. 



A single specimen from the base of ^It. iloraima, 3500 feet. 



Otophryne, g. n. Eii(jy,sto7uutidarum. 

 Pupil round. Tongue large, oval, truncate and free behind ; no teeth on the palate ; 

 two denticulated dermal ridges in front of the pharynx. Tympanum very distinct. 

 Fingers free, toes webbed at the base, the tips merely swollen. Outer metatarsals 

 united by the integument. Precoracoid jjresent, weak ; sternum cartilaginous. Sacral 

 diapopliyses rather strongly dilated *. 



3. Otophryne robusta, sp. n. (Plate 5. figs. 5, 5 a.) 



Habit stout; head rather small. Snout short, pointed, obliquely tnmcated at the end 

 and projecting beyond the mouth, which is inferior, well within the lines of tiie canthi 

 rostrales ; nostril equally distant from the eye and the end of the snout ; eye rather 

 small, little prominent ; interorbital space nearly twice as broad as the upper eyeUd ; 

 tympanum very large, close to the eye and once and a half its diameter. Fingers short, 



• Osteological characters ascertained by means of a sciagraph kindly prepared by Messrs. Gardiner and Green.
