Show 232 MR. G. A" B O U L E N G E R O N T H E [Feb. 2, in Luzon, in Batjan, and in Celebes. The specimens (12) collected by the Drs. Sarasin are from the following localities :--Masarang, Tomohon, Burukan, Buol, Wangkahulu Valley, and Lake Posso. 10. BANA EVERETTI, Blgr. Nine specimens : Masarang Chain, Tomohon, Bone Valley (named R. chalconota by Midler), 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. R. 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 Rhacophorus. 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 between 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 ; upper caudal crest dark brown, lower greyish. Total length 45 millim.; body 14; tail 3 1 ; depth of tail 8. This tadpole is essentially that of a typical Rana. 11. BANA CELEBENSIS, Ptrs. Vomerine teeth in two small oblique series between the choana?. Head moderate, depressed, as long as broad; snout subacuminate, 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 very distinct, three-fourths the diameter of the eye and close to it. Fingers moderate, first extending as far as |
