508 ON REPTILES AND BATRACHIANS FROM BORNEO. [JuQC 14, 



Fingers entirely webbed, the disks smaller than the tympanum ; toes 

 webbed to the disks, which are smaller than those of the fingers ; 

 subarticular tubercles feebly developed. Tibio-tarsal articulation 

 reaching the tip of the snout. Skin smooth, feebly granulate on the 

 belly ; a slight dermal fringe along forearm and tarsus ; a dermal 

 flap above anus and at heel. Yellowish, with a few purplish dots on 

 head and back ; a purplish line round the snout, from eye to eye, 

 passing through the nostrils. 



From snout to vent 43 millim. 



A single specimen.

8. Calopheynus pleurostigma, Tsch. 



9. Callula baleata, S. Miill. 



10. Nectophevne hosii, sp. n. (Plate XXX. fig. 2.) 



Head broader than long ; snout short, obliquely truncate ; cauthus 

 rostralis strong; lorealregion nearly vertical, concave; interorbital space 

 broader than upper eyeUd, slightly concave ; tympanum distinct, 

 vertically oval, half the diameter of the eye. Fore limb long and 

 { strong ; fingers webbed at the base, ending in rather large subtrian- 

 gular expansions, first much shorter than second ; toes short, with 

 small distal expansions, extensively webbed, but the three distal 

 phalanges of the fourth toe free ; subarticular tubercles well de- 

 veloped ; two small, flat metatarsal tubercles ; a tarsal fold. Tarso- 

 metatarsal articulation reaching between eye and end of snout. 

 Above with small scattered warts, beneath finely granulate ; a short 

 and narrow, but very prominent parotoid gland. Browu ; throat 

 blackish. Male with an internal subgular vocal sac. 



From snout to vent 60 millim. 



A single male specimen. 



11. BtJFO aUADEIPOECATUS, Blgr. 



12. BuFO ASPEE, Gravh. 



Besides several small and perfectly typical examples, the collec- 

 tion contains a large female, measuring 215 millim. from snout to 

 vent, which agrees in every respect with B. asper except in the much 

 greater development of the parotoid glands, the length of which 

 equals their distance from the end of the snout and twice and a 

 half their width ; they are disposed very obliquely, diverging behind. 

 I have felt tempted to describe this specimen as a distinct species ; 

 if I abstain from doing so it is because I can detect no other ground 

 for such a separation than the size and form of the parotoids, a 

 character which varies so much in certain other species of this 

 genus — B. marinus, B. regularis, and B. viridis, for instance.
