Show 482 DR. A. G U N T H E R O N N E W BATRACHIANS. [June 25, the nostril to the sacrum. Limbs with brownish-black cross bands the interspaces tinged with pink. Lower parts greyish, with numerous small white specks. Mr. E. Bartlett found a single specimen of this species at Chyavetas, Eastern Peru. It is 40 millims. long, hind limb 58, fourth toe 19 millims. NANNOPHRYS, g. n. ASTEROPHRYD. Fingers and toes tapering, free to the base ; lower jaw with a pair of very slightly prominent apophyses in front and with a pointed symphysial tubercle; the internal openings of the nostrils and eustachian tubes small; tympanum of moderate size, distinct. No parotoids. The transverse processes of the sacral vertebra dilated into a flat triangle. Vomer with two very inconspicuous prominences on which no teeth can be distinguished. Tongue deeply forked behind. Upper eyelid flaccid, without prominent edge. NANNOPHRYS CEYLONENSIS. Similar in habit to a young Rana kuhlii. Head broad, depressed, short, the snout being as long as the diameter of the eye : canthus rostralis distinct; loreal region sloping ; nostril close to the end of the snout. Eye of moderate size, prominent. Tympanum half as large as the eye. A lineal fold runs from the hinder edge of the orbit, over the tympanum, towards the arm-pit. Cleft of the mouth broader than long; tongue rather narrow. The vomerine prominences are situated on a level with the hinder edge of the choanae. Skin slightly tubercular; an indistinct fold across the crown of the head from one hinder angle of the orbit to the other. Limbs of moderate length, the length of the body being rather more than the distance of the vent from the heel. The third finger rather longer than the fourth, which is scarcely longer than the second. Metatarsus with one inconspicuous tubercle. The fourth toe is not quite half as long as the body ; the third is a little longer than the fifth. Upper parts brown, marbled with darker; limbs with dark cross bands. Upper lip with some small white spots ; a pair of white spots below the vent. Lower parts whitish. I have examined four examples from Ceylon, probably from the southern parts. They are 25 millims. long, the hind limb being 37 millims. ; but I have reason to believe that the species grows to a larger size. CACOTUS, g. n. BOMBINATORIN. Fingers and toes tapering. Maxillary and vomerine teeth distinct. Tongue broad, slightly notched behind. Toes quite free ; metatarsus with two tubercles. Tympanum absent; eustachian tubes reduced to a minute foramen. Transverse processes of sacral vertebra not dilated. CACOTUS MACULATUS. (Plate XXXVIII. fig. 5.) Similar in habit to Pleurodema bibronii. Head of moderate width. |
