HARBOUR: AMPHIBIA AND REPTILIA. 131 



porals are normal 2 + 3 on both sides. There is but one preocular and nine 

 supralabials on each side; of these 4 and 5 enter the orbit. The scales are in 

 19 rows, anal is divided, ventrals, as already mentioned, 139, while part of the 

 tail has been lost, only 54 pairs of subcaudals remaining. 



PSEUDOXENODON siNENSis Boulenger. 



BOULENGER, Ann. mag. nat. hist., 1904, ser. 7, 13, p. 134. 



This form, which Boulenger remarks is so very nearly related to P. macrops 

 (Blyth), is nevertheless a distinct and easily distinguishable one. As it was 

 reported by the describer from both Yunnan and Szechwan, it is not surprising 

 to find a typical example from Laolingkung, western Szechwan at an altitude 

 of 10,300 feet. Not long ago I was fortunate enough to get a specimen taken 

 at Ytinnanfu by Mr. Graham at 6,000 feet altitude. Boulenger's Yunnan 

 records were based on specimens taken by the same collector in the same locality. 

 Both of these examples come within the range of variation which Boulenger 

 cites for the five previously published specimens. 



So far as known the species is confined to Szechwan and Yunnan.

Dr. Stejneger (loc. cit.) has treated this form as one which he must consider 

 nominally of specific value until it can be actually shown to join the Indian Krait 

 B. caeruleus. The differences, however, are of such slight value that they do 

 not warrant more than subspecific rank, even though our present insufficient 

 material does not permit of our showing now the intergrading with not only 

 the typical race, but also with the considerably more distinct Malaysian form, 

 B. candidus. 



This race, which is distributed through southern China from "The moun- 

 tains north of Kiu-kiang" on the Yangtze-kiang to Kwangtung, Kwangsi, and 

 the islands of Hainan and Formosa. Mr. Zappey's example from Ichang, 

 Hupeh seems the first taken in that province and extends considerably the 

 hitherto known range into western China.
