Frogs and Snakes from Yunnan. L31 



about 6000 feet) by Mr. John Graham, of the China Inland 

 Mission. The Natural History Museum has since received 

 from the same gentleman further collections made in the same 

 district, and among them I had the pleasure of finding 

 examples of two new frogs and five new snakes, of which 

 descriptions are here offered. 



Rana pleuraden. 



Vomerine teeth in two small oblique groups between the 

 choana?. Head moderate, as long as broad ; snout obtusely 

 pointed, prominent, as long as the orbit ; canthus rostralis 

 obtuse; loreal region oblique, concave; nostril equally 

 distant from the eye and from the end of the snout ; inter- 

 orbital region narrower than the upper eyelid; tympanum 

 very distinct, two thirds to three fourths the diameter of the 

 eye. Fingers and toes rather slender, obtusely pointed ; 

 first finger extending beyond second ; toes half-webbed ; 

 subarticular tubercles rather feeble ; a small oval inner meta- 

 tarsal tubercle. The tibio-tarsal articulation reaches between 

 the eye and the tip of the snout. Skin smooth or with small 

 warts; a moderately broad, very prominent, dorso-lateral 

 glandular fold; no other folds on the body. Olive-brown or 

 greyish above, spotted with black ; a light vertebral streak 

 usually present ; a dark brown or blackish band on each side 

 of the head, passing through the eye and involving the 

 tympanum ; a whitish streak along the upper lip ; limbs with 

 more or less regular black cross-bars ; sometimes a light line 

 along the inner side of the leg, continued to the outer toe ; 

 hinder side of thighs marbled black and yellow ; lower parts 

 white, throat sometimes brownish. Male with a vocal sac on 

 each side, forming loose folds on the throat, and a very large 

 flat gland on each side of the body, above and behind the 

 shoulder. 



From snout to vent 63 mm. 



Several specimens. 



Callula verrucosa. 



Snout rounded, not prominent, as long as the eye ; inter- 

 orbital space as broad as the upper eyelid. Fingers slender, 

 with slightly swollen tips, first a little shorter than second ; 

 toes moderate, nearly half-webbed, the tips blunt, not swollen, 

 fifth considerably shorter than third ; subarticular tubercles 

 well developed; metatarsal tubercles two, oval, compressed, 

 the inner very large. The tibio-tarsal articulation reaches 

 the shoulder or between the shoulder and the eye. Upper
