XXXVI. — Descriptions of new Reptiles and Batrachians from 

 the Loo Choo Islands. By G. A. BoULENGER. 



A COLLECTION of Reptiles and Batrachians recently made by 

 Mr. Hoist on Okinawa, or Great Loo Choo, contains, in addi- 

 tion to most of those previously reported by me (Proc. Zool. 

 Soc. 1887, p. 146) as obtained by the late Mr. H. Pryer, 

 examples of the following known species and of three which 

 T regard as undescribed : — 



Nicoria Spengleri, Gm. ; Eumeces marginatus^ Hallow. ; 

 Dinodon semicarinatus {^Euniesodon semicarinatus^ Cope, 

 = Lepidocephalus fasciatusj Hallow.); Callophis japonicus, 

 Gthr. ; Rana macropus, Blgr. 



Trimeresurus okinavensis, sp. n. 



Snout short, obliquely truncate, prominent, with sharp 

 raised angle all round ; eye rather small. Rostral deeper 

 than broad^ not visible from above; upper head-scales small, 

 juxtaposed or subimbricate and smooth on the snout and 

 vertex, imbricate and obtusely keeled on the occiput ; 6 to 9 

 scales in a transverse series between the supraoculars, which 

 are large, larger than the eye ; a pair of scales behind the 

 rostral, separating the internasals in front ; three series of 

 scales between the eye and the upper labials ; 7 or 8 upper 

 labials, second entering the loreal pit, third largest ; temporal 

 scales obtusely keeled. Scales strongly keeled, in 21 or 23 

 rows. Ventrals 129-130 ; anal entire ; subcaudals 43-47 

 pairs. Brown above, with darker cross bands or alternating 

 large quadrangular blotches; upper surface of head dark 

 brown, sides blackish, with a lighter streak along the temple ; 

 lower parts brown, with a series of blackish blotches on each 

 side, partly on the ventrals, partly on the two lower rows of 

 scales. 



Total length 350 millim. ; tail 60. 



Closely allied to T. monticola, Gthr. Distinguished by 

 the somewhat larger eye, the raised canthus rostralis, and the 

 strongly keeled scales. 



Rana Holsti, sp. n. 



Near R. temporaria. Vomerine teeth in two well-developed 

 oblique groups behind the level of the choanaj. Head 

 broader than long ; snout rounded, slightly prominent, as 

 long as the diameter of the orbit ; loreal region nearly 

 vertical, slightly concave ; nostrils a little nearer the end of the
