Show 1900.] BATRACHIANS AND REPTILES OF THE GABOON. 443 the first under the nostril, the second below the anterior third of the eye; limbs with rather indistinct dark cross-bars; lower surface of cms and tarsus dark brown. From snout to vent 70 millim. A single specimen from the Benito Biver (67. L. Bates). TRICHOBATRACHUS, 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. TRICHOBATRACHUS ROBUSTUS, sp. n. (Plate XXX.) General appearance suggestive of Rana liebigi Gthr. Vomerine teeth in two short transverse series between the rather large choanae. 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; iuterorbital 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; subarticular 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-edo-ed 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 2 ) fr°m t o e Benito Biver (67. 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 |
