Hyliedactylus bivittatus, Cantor; Vatal. Malay Rept. p. 143. 



Snout very blunt and short ; a rudiment of a membrane between 

 the toes hardly conspicuous. Light brown, with a large triangular 

 dark bro\vn spot, covering nearly the whole of the back, beginning 

 wth a tiimcatcd tip between the eyes and becoming broader poste- 

 riorly ; whitish spots on the joints only visible in younger indi- 

 viduals.

3. Kaloula picta. 



Plectropus pictus, (Bibron) Et/doiuc et Souleyet, Voy. de la Bonite, Beat. 

 pi. 9. f. 2 ; Dam. ^ Bibr. p. 737. 



Muzzle rather blunt, not very short, angular; toes one-third 

 webbed. Olive or brownish, the darker coloration of back sometimes 

 forming a large triangular spot, with a tapering end on the occiput, 

 sometimes separated in more or less confluent spots ; no white spots 

 on the joints. 



A. Male = Ph'ctropits pivtus, Bihr. Tips of fingers and toes very 

 shghtly enlarged, cylindrical, scarcely dilated; inner tubercle of 

 metatarsus large, flat, round, not shaq). 



a. Advilt. Philippine Islands. 



B. Female. Tips of flngers and toes much dilated, ends of fingers 

 broader than tliat of toes ; inner tubercle of metatarsus oval, rounded, 

 moderate. 



h-d. Adult. Philippine Islands. 

 e. Adult. Pliihppine Islands. 



The male indi\'idual in the British Museum Collection belongs 

 undoubtedly to that form of Batrachians called by Bibron Plectropus 

 pictus. On the other hand, another Batracliian from the Philippine 

 Islands, with all the characters of Kaloula, agrees so perfectly with 

 Plectropus, except in the diaracter of the toes, as to lead me to 

 believe that both forms arc identical, one being the male, and the 

 other the female. A comparison of more specimens vdW. no doubt 

 show till- tnith of my belief that there exist sexual difterences in 

 the third species of Kaloula, and that hitherto only the male was 

 known, and described by Bibron as Plectropits pictus.
