The female (U.S.N.M. No. 34174, same locality and collector) 

 differs in the tail gradually tapering- front the base, and in the shorter 

 hind leg, the tips of the fourtn toe scarcely reaching beyond the elbow. 



The young (U.S.N.M. No. 34178; snout to vent 31 mm.) is essen- 

 tially like the female. In this specimen the interparietal is com- 

 paratively larger, but the occipital is nearly obsolete. In a Chinese 

 specimen of same size (U.S.N.M. No. 35526) both of these shields 

 are uncommonly large, with a small square shield between them. 



Variation. — In the Formosan series of nine specimens there is but 

 little individual variation. All have one inguinal pore; three pairs 

 of chin-shields; six rows of enlarged dorsals; and the nasals broadly 

 in contact or at least totiching behind the rostral. None of the speci- 

 mens, including the Chinese, has any outer accessory dorsal scale row. 

 The color is also essentially alike, except that in several specimens a 

 distinct whitish line on the inner half of the otiter dorsal row of scales 

 forms the upper edge of the lateral dark band, while the dorsal 

 median black lines are often absent or obscure. 



Habitat. — Widely distributed over eastern China in the mountains, 

 on the coast from Fokien to Ningpo, west to the provinces of Kansu, 

 where it was collected by Berezowski in 1892, and Shensi, where 

 Dr. E. Blackwelder obtained it in 1904. 



In Formosa it was taken during March, 1903, by Mr. Owston's 

 collector at Taipe, the specimens being in the Iinited States National 



Museum.
