130 SOME CHINESE VERTEBRATES. 



extent of its vertical distribution in China. The scale formula of 23 rows, 230 

 ventrals, and 104 subcaudals is typical. Two other specimens without data 

 are from either Hupeh or Szechwan. 



Stejneger says, "Ranging from Darjeeling in the west to Formosa and the 

 Amur Province in the east, this species has the regular Himalayo-Chinese 

 distribution."

A specimen in every respect typical, from Ichang, Hupeh. This species 

 is a common one ranging throughout China and Korea.

A single typical specimen increases considerably the known range of this 

 species. Stejneger speaks of it as "apparently restricted to the lower Yangtse 

 Valley and coasts of eastern China, between Hongkong and Shanghai, as well 

 as to Formosa." The example in hand, however, comes from "eight days' 

 journey northwest of Ichang, Hupeh." It has been compared with a specimen 

 from Formosa, in this Museum (T. Barbour coll.), and found to be almost iden- 

 tical. In both specimens the rostral shield is divided.

A single specimen from Ichang whence the species does not appear to have 

 been previously recorded. A. E. Pratt reported the species common about 

 Kiukiang much lower down the Yangtze. The species ranges over middle 

 China and Formosa. The specimen shows only 139 ventrals, while Boulenger 

 notes a range of from 145 to 161. Another difference is the three postoculars 

 in addition to the subocular on one side; on the other side the normal condi- 

 tion of 2 + 1 obtains. Again on one side the loreal is deeper than broad, while 

 the normal opposite is found on the other side. The outer row of scales is 

 without keel, as are also a considerable number in the second row. The tern-
