the first under the nostril, the second below the anterior third 

 of the eye ; limbs with rather indistinct dark cross-bars ; lower 

 surface of crus and tarsus dark brown. 



From snout to vent 70 millim. 



A single specimen from the Benito River (G. L. Bates). 



Tbichobatrachus, g. n. 



Pupil vertical. Tongue subcordiform, free and notched behind. 

 Vomerine teeth. Tympanum distinct. Fingers free ; toes webbed. 

 Outer metatarsals bound together. Omosternum with a bony style; 

 sternum a cartilaginous plate, without style. Terminal phalanges 

 simple, obtuse. 



To these characters might be added the villose dermal papillae 

 which cover some parts of the body, whence the name proposed 

 for this new genus, were it not that I suspect it to be a mere 

 seasonal peculiarity ; far from being a nuptial attribute of the males, 

 as one might have been inclined to suppose from analogy with 

 various Fishes, the character is more strongly developed in the 

 female than in the male. 



25. Tbichobatbachus bobtjstus, sp. n. (Plate XXX.) 



General appearance suggestive of Sana liebigi Gf-thr. Vomerine 

 teeth in two short transverse series between the rather large 

 choanse. Head larger, broader than long, much depressed ; snout 

 very short, rounded, with distinct canthi and very oblique, slightly 

 concave lores ; nostril slightly nearer the eye than the end of the 

 snout ; interorbital space a little broader than the upper eyelid ; 

 tympanum moderately distinct, half the diameter of the eye. 

 Limbs robust ; tips of digits slightly swollen ; first finger much 

 longer than second, as long as third ; toes half-webbed : sub- 

 articular tubercles large ; a feebly prominent, elongate, inner 

 metatarsal tubercle. The tibio-tarsal articulation reaches the eye. 

 Skin smooth; sides of body, back of thighs, and a stripe along the 

 upper surface of the latter with hair-like papillae, more developed 

 in the female thau in the male. Olive-brown above ; a darker, 

 black-edged broad band along the back, fading away behind and 

 sharply defined in front by a black cross-bar between the eyes ; 

 a black canthal and temporal streak ; sides of body and limbs 

 blackish ; lower parts white, female with brown dots on the throat. 

 Male with a pair of internal vocal sacs, and with three short ridges 

 (two longitudinal and one transverse) of small horny black spines 

 on the inner side of the first finger. 



From snout to vent 110 millim. 



Two specimens ( d $ ) from the Benito River ( G. L. Bates). 



Dilobates, g. n. 



Pupil vertical. Tongue subcordiform, free and notched behind. 

 Vomerine teeth. Tympanum distinct. Fingers free ; toes nearly 

 free, with a slight rudiment of web. Outer metatarsals bound
