as wide as supraoculars, six-sided forming an obtuse angle in front and

 shorter than their distance from tip of snout, rather broad; nostril 

 small, in a very small and narrow triangular nasal between rostral, 

 first supralabial and prefrontal; one preocular; one postocular; no 

 temporals; a large shield bordering posterior half of parietal behind 

 fourth supralabial; four supralabials, first and third sub- 

 equal, small, second twice as large as third, fourth as long 

 as second and third together, second and tliird entering

Habitat. — This species is only known from the two types collected 

 by Mr. Berezowski in the Chinese province of Sze-chuen, and the spec- 

 imen brought home by Mr. T. Tada from Taipa, Formosa, where he 

 obtained it in September, 1897. It is probably also to be found in the 

 intervening territory.
