men with 21 rows, as he did also one with 25. These came from 
Altai, Siberia. Stejneger’s subspecies has been found in inland 
mountain ranges, further south, about Ichang, Ningpo, Chekiang, 
and Kiu Kiang; while this race has been known from an enormous 
belt to the northward.

Stejneger (Herp. of Japan, 1907, p. 480) wrote at the end of his 
remarks on 7’. okinavensis that no near ally of this species was known 
from Formosa. He notes its relationship to T. monticola, and says, 
“the latter or a related form may be expected to occur in that island 
[Formosa].’”’ It is interesting to record now how correct Stejneger’s 
surmise was. A fine specimen from Tapposha, Mt. Arizan, central 
Formosa, was acquired with the Owston material. It is colored as 
Indian specimens are, but differs very slightly in having 10 scales 
separating the supraoculars and 10 supralabials. ‘The scale rows 
are 27 in number, which Boulenger states is a rare condition. V.

It is interesting to record a specimen of this species from Amami 
Oshima, Riu Kiu Islands. Dr. Stejneger (J. c.) wrote, “The few 
specimens known of this species have nearly all come from Okinawa 
shima. According to a recent paper by Dr. Wall, the collector of
