HYLORANA. 423 



China and the Philippine Islands ; in the Himalayas it ascends to an altitude of 9000 feet. 

 We have never received it from New Guinea or from any of the Indo-Australian islands. It 

 attains to a length of 5 inches. Cantor says that it utters a chirping, plaintive sound. 



Dumeril and Bibron (Erpet. gen. viii. p. 702) describe a species, Bufo isos, as very similar to B. melano- 

 stidus, but provided with narrow, elongate, tapering parotoids, and with toes entirely webbed. They state 

 that they received two examples fi'om Bengal. It would be very singular that this species should never 

 have been sent to any of the British collections, if it really be a Bengal species. However, we have lately 

 received the typical specimen of Dr. v. Bleeker's Bufo yymnauchen from Bintang (Nat. Tydschr. Nederl. 

 Ind. 1858, xvi. p. 46), a species so similar to Dumeril and Bibron's B. isos that we believe them to be 

 identical. There is only one point in which Dumeril's description does not agree with our specimen, viz. 

 in the length of the first and second fingers, which are said to be equal in B. isos, whilst the first finger is 

 the longer in B. gymnauchen, although Bleeker also describes them as equal. If the toes be laid side by 

 side, they appear to be equal ; but if their actual measurements are taken, the greater length of the first 

 finger is at once conspicuovis. The figure Ulusti-ating the Bufo isos in Belanger, Voyage aux Indes Orien- 

 tales, Kept. pi. 7, is monstrous.

Crovpn of the head concave, the orbital edge being swollen, and continued posteriorly into 

 a short, obtuse protuberance. Parotoids small, sub triangular, separated from the protuber- 

 ance by a fold. Tympanum distinct, but very small ; eyes prominent, with the upper eyelid 

 broad. Canthus rostralis angular. Upper and lateral parts covered with numerous larger 

 and smaller tubercles, each with a small horny point ; the crown of the head and the snout 

 are also tubercular. A very conspicuous groove along the vertebral line. Legs not very 

 short, the length of the body being equal to the distance between the vent and the metatarsal 

 tubercle. Metatarsus with two rather small, subequal, elliptic tubercles ; a cutaneous fold 

 along the inner side of the tarsus. Toes nearly entirely webbed. Uniform brown above, 

 yellowish below. 



This species is found in Java, Borneo, Celebes, Sumatra, and in Mergui ; it attains to a 

 length of 5^ inches. Its physiognomy is very peculiar, in consequence of the prominent eyes 

 and of the short snout, with angular canthus rostralis and perfectly vertical loreal regions. 



HYLORANA, Tschudi. 



Skill smooth, generally a glandular fold along each side of the back. 

 Vomerine teeth present. Tongue elongate and deeply notched behind. 

 Tympanum distinct. Limbs generally slender ; fingers quite free, toes 

 broadly webbed; disks of the fingers and toes not much developed. 



Although the name of this genus is incorrectly formed, we have preserved it, not only
