232 MR. G. a" boulenger on the [Feb. 2, 



in Luzon, in Batjan, and in Celebes. The specimens (12) collected 

 by the Drs. Sarasin are from the following localities : — Masarang, 

 Tomohon, Eurukan, Buol, Wangkahulu Valley, and Lake Posso. 



10. Eaxa eveeetti, BIgr. 



Nine specimens : Masarang Chain, Tomohon, Bone Valley (named 

 B. chalconota by Miiller), Wangkahulu Valley ; Luhu, lowland. 

 S. Celebes, 2000 feet (Everett). 



The specimens referred to R. chalconota by Peters probably 

 belong to this species, first described from the Philippines and 

 since found in Borneo. B. everetti is easily distinguished from 

 R. varians by having the first finger shorter, not extending quite 

 so far as the second, and larger disks to the fingers, their diameter 

 equalling one-half to two-thirds that of the tympanum. The 

 tibio-tarsal articulation reaches the tip of the snout or a little 

 beyond. Males with internal vocal sacs and no humeral gland. 

 A white streak usually borders the upper lip. 



The Drs. Sarasin have observed this Frog to lay its eggs in a 

 frothy mass out of the water, forming a sort of nest as in Rhaco- 

 jjhonts. A series of specimens at various larval stages, collected 

 by Mr. Everett at Indrulaman, S. Celebes, enable me to give a 

 description of the tadpole : — 



Length of body once and a half to once and two-thirds its width, 

 about half as long as the tail. Nostrils nearly equally distant 

 from the eyes and the tip of the snout. Eyes on the upper 

 surface, equally distant from the tip of the snout and the 

 spiraculum, the distance bet^^■een them a little greater than the 

 distance between the nostrils. Spiraculum on the left side, 

 directed upwards and backwards, nearer the posterior extremity of 

 the body than the end of the snout. Anal opening on the right 

 side close to the lower edge of the caudal crest. Tail about thrice 

 and a half as long as deep, acutely pointed ; crests lower than the 

 muscular portion, the dorsal not extending on the body. Mouth 

 as broad as the interocular space ; series of labial teeth -*-, the 

 outer upper and the three lower continuous, the others restricted 

 to the sides ; lower lip bordered by a double series of papillae ; 

 beak broadly edged with black. Dark brown or blackish above, 

 greyish below ; upj^er caudal crest dark brown, lower greyish. 



total length 45 millim. ; body 14 ; tail 31 ; depth of tail 8. 



This tadpole is essentially that of a typical Rana. 



11. Eana celebbnsis, Ptrs. 



Vomerine teeth in two small oblique series between the choanae. 

 Head moderate, depressed, as long as broad ; snout subaeuminate, 

 prominent, as long as the diameter of the orbit ; canthus rostralis 

 strong ; loreal region concave ; nostril a little nearer the tip of the 

 snout than the eye ; interorbital space as broad as the upper 

 eyelid ; tympanum mqtj distinct, three-fourths the diameter of the 

 eye and close to it. Fingers moderate, first extending as far as
