The family Dyscophidae, with Madagascar as its head- 

 quarters, was known to be scantily represented in Burma 

 and Siam [Calhiell'i, Stol.). and Borneo (^Colpoglossus, Blgr,, 

 Calliglutus, Barbour & Noble). Yunnan may now be added 

 to the range of its distribution in Asia. 



Calluella yunnanensis , sp. n. * 



Habit rather stout, similar to Microhyla rubra, Jerd. 

 Head much broader than long ; snout rounded, not [)roject- 

 ing beyond the mouth, as long as the eye ; canthus rostralis 

 feeble ; loreal region very oblique ; nostril equally distant 

 from the eye and from the tip of the snout ; interorbital 

 space as broad as the upper eyelid. Pupil round. Fingers 

 with obtuse tips, first shorter than second, half as long as 

 third ; subarticular tubercles moderately large, feebly pro- 

 minent ; three carpal tubercles, median smallest. The 

 tibio-tarsal articulation reaches the shoulder or the temple ; 

 heels feel)ly overlapping when the limbs are folded at right 

 angles to the body ; tibia shorter than the foot, 2^ to 

 "Z^ times in length from snout to vent; toes moderately 

 long, with slightly swollen tips, the w^eb reaching the tips, 

 but deeply emarginate ; subarticular tubercles moderately 

 large, feebly prominent ; two metatarsal tubercles, inner 

 oval, somewhat compressed and very prominejit, | the length 

 of the inner toe, outer smaller, round and flat. Skin smooth, 

 except for some feebly raised glandular ridges which corre- 

 spond with the outlines of the markings. Pale greyish or 

 pinkish brown above, with a symmetrical vase-shaped brown 

 marking, edged with darker and lighter, from between the 

 eyes to the sacral region ; a dark lateral band from the eye 

 to the groin, bordered above by a series of more or less con- 

 fluent black spots, which extends forwards to the canthus 

 rostralis ; limbs with dark cross-bars, one or two on the 

 tibia ; lower parts white, mottled with brown, especially on 

 the throat. 



From snout to vent 29 mm.
