12 Records of the Indian Museum. [Vol. VIII, 



Ten specimens of M, horealis were taken under stones in a 

 stream at Rotung and one a few miles vS. of Yembung. 



10. Rhacophorus maximus, Giinth. 



Boulenger, Fauna, p. 472. 



A common species on the lower slopes of the Darjiling Hima- 

 layas and the Khasi Hills. Colonel Godwin-Austen obtained speci- 

 mens in the Dafla country. 



Mr. Kemp obtained a half-grown specimen at Upper Rotung 

 at an altitude of about 2,000 ft. 



II. Rhacophorus bimaculatus, Boulgr. 



Boulenger, Fauna, p. 472. 



Not uncommon in the Khasi Hills. Mr. Kemp's only speci- 

 men, which was taken at Rotung (alt. 1,300 ft.) in January, has 

 the web of the feet of a bright scarlet colour and lacks the dark 

 spots on the sides usually so characteristic of the species. In the 

 former particular it agrees with other specimens in our collection. 



12. Rhacophorus naso, sp. nov. 

 (Plate ii, fig. 3.) 



This peculiar species can be distinguished from any other of 

 the genus that occurs in Assam or Burma by the dermal appendage 

 on its snout. 



Habit moderately stout. I^ength from snout to vent 43 mm. 



Head rather broad, triangular, with convex sides; snout much 

 longer than orbit, pointed, convex aboi^e, nostril much nearer tip 

 of snout than eye ; canthus rostral is indistinct ; loreal region con- 

 cave almost horizontal. Diameter of tympanum, which is dis- 

 tinct, about I that of eye. 



Mouth. — No prominent tooth at apex of lower jaw ; no papilla 

 on the tongue; vomerine teeth forming two small, almost circular 

 patches, one close to the inner margin of each choana ; choanae 



small. 



Skin of dorsal surface rugose with many prominent and 

 irregular tubercles ; a small subquadrangular dermal projection on 

 the snout ; rounded tubercles scattered on the basal part of the 

 thighs; ventral surface coarsely granular, more so on the chest 

 and throat than on the belly. A fairly distinct dorso-lateral fold 

 and a more prominent one running from the eye above the tympa- 

 num to the shoulder ; serrated cutaneous fringes on the outer edges 

 of the forearm and the shin. 



Limbs stout, not very long. Fingers with a rudimentary web; 

 their disks well developed, transversely oval; that on the third 

 finger almost as large as the tympanum; subarticular tubercles 

 well developed. The tibio-tarsal articulation reaches the eye ; toes 

 almost completely webbed ; their disks like those of the fingers ;
