134 SOME CHINESE VERTEBRATES. 
on the extremities of the ventrals; between these two series of spots runs a 
zigzag black continuous band. On top of the head there is a dark blotch running 
‘from the edge of the frontal to a band from eye along neck. A rough horseshoe- 
shaped mark on the nape of the neck with the bow directed forward. The 
figures of this example compared with one of A. b. brevicaudus Stejneger show 
how radical is the difference in type of marking between the two forms, as well 
as the other divergences. 
When showing the type of this species to Dr. Stejneger, he at once confirmed 
my decision to describe it as new, and remarked that he did not believe it to be 
very nearly related to any of the described forms, but to represent a species by 
far the most primitive of any in the genus. This is, of course, exactly what one 
might suppose would be the case with a form coming from the habitat of A. 
tibetanus.

Five specimens taken among Cacti on the sandy shores of the Tung River 
in western Szechwan. These show no essential differences from Anderson’s 
figure except that in none of these examples, and one is an adult male, do the 
spines of the weak nuchal crest reach the length which his figure shows. For 
in that three or four spines on the nape have a length almost equalling the 
diameter of the orbit, in none of these is the length one third as great. The 
types came from Momein or Tengyuehchow in western Yiinnan. Swinhoe 
has collected the species in Szechwan.

A single specimen from Ichang, the type locality and the only one from 
whence the species has been reported, differs somewhat from the original descrip- 
tion. There is only one loreal, which, however, forms a suture with the fronto- 
nasals. There is also only one pair of nuchals. The second azygos postmental 
is separated from the first by the meeting on the median line of a pair of large ~_
