Kaloula pulchra, Grai/, Zool. Misc. p. 38. 



Hyleedactylus bivittatus, Cantor ; Catal. 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 brown spot, covering nearly the whole of the back, beginning 

 with a truncated 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, (Bihron) Eydoux et Soideyet, Voy. de la Bonite, Rept. 

 pi. 9. f. 2 ; Dum. Sf Bihr. 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^Plectropiis pictus, ^\\jY. Tij^s of fingers and toes very 

 slightly enlarged, cylindrical, scarcely dilated ; inner tubercle of 

 metatarsus large, flat, round, not sharp. 



a. Adult. Philippine Islands. 



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

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

 moderate. 



h-cl. Adult. Philippine Islands. 

 e. Adult. Phihppine Islands. 



The male individual in the British Museum Collection belongs 

 undoubtedly to that form of Batrachians called by Bibron Plectropus 

 pktux. On the other hand, another Batrachian from the Philippine 

 Islands, rvith all the characters of Kaloula, agrees so j)ei"feetly with 

 Plectropus, except in the character 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 will no doubt 

 show the truth of my belief that there exist sexual differences in 

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

 known, and described by Bibron as Plectropus pictus.
