(Published by permission of the Trustees of the British Museum.) 
Tue family Dyscophide, with Madagascar as its head- 
quarters, was known to be scantily represented in Burma 
and Siam (Cadlluella, 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 project- 
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 feebly overlapping when the limbs are folded at right 
angles to the body; tibia shorter than the foot, 24 to 
24 times in length from snout to vent; toes moderately 
long, with slightly swollen tips, the web reaching the tips, 
but deeply emarginate ; subarticular tubercles moderately 
large, feebly prominent ; two metatarsal tubercles, inner 
oval, somewhat compressed and very prominent, ? 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. 
Two specimens from Yunnan Fou, from the collection of
