Rana martensi, sp. n. 



Allied to B. temporaria. Vomerine teeth in two rather oblique 

 oval groups, extending posteiiurly beyond the line of the choanae. 

 Head about as long as broad, very similar to that of R. agilis ; 

 nostril equally distant from the eye and the end of the snout ; 

 iuterorbital space narrower than the upper eyelids ; tympanum 

 rather large, its diameter equalling about two thirds that of the eye, 

 from which it is separated by a space equal to about half its 

 diameter. The first finger extends beyond the second. The tibio- 

 tarsal articulation reaches the eye or the nostril ; tibia shorter than 

 the fore limb. Inner metatarsal tubercle rather strong, blunt, oval ; 

 outer tubercle absent, or scarcely marked ; subarticular tubercles of 

 fingers and toes moderate ; toes t«o-thirds webbed. Skin smooth ; 

 lateral fold rather narrow, moderately prominent. Coloration very 

 similar to that of R. agilis, save that the whitish streak bordering 

 the temporal spot inferiorly does not extend forwards beyond the 

 eye. Male with internal vocal sacs. 



Yedo ; several specimens (4410, 4411) in the Berlin Museum, 

 one of which was obtained for the British Museum. Collected by 

 Dr. E. von Martens {cf. Preuss. Exped. n. Ost-Asien, Zool. i. 

 p. 111). 



Rana macropus. 



Ixalus jcqwnicus, Hallow. Proc. Ac. Philad. 1860, p. 501. 



Vomerine teeth in two rather indistinct oblique series between the 

 choanae, widely separated in the middle. Snout obtuse, as long as 

 the diameter of the orbit ; nostril nearer the end of the snout than 

 the eye; canthus rostralis well maiked, curved; loreal region con- 

 cave ; eye large ; iuterorbital space narrower than the upper ej elid ; 

 tympanum very distinct, measuring not quite half the diameter of 

 the eye. Fingers moderate, slightly depressed, first shorter than 

 second ; toes moderate, three-fourths webbed ; tips of fingers and 

 toes dilated into well-developed disks, which are much smaller than 

 the tympanum j subarticular tubercles moderate ; a single, oval, inner 

 metatarsal tubercle ; no tarsal fold. When the fore limb is stretched
