last four supralabials, crossing to the lower jaw; sides of face anterior

Variation. — Supralabials vary between 8 and 7, ventrals between 

 127 and 134, subcaudals between 42 and 51 pairs in the three speci- 

 mens wliich have thus far been recorded. Doctor Wall reports one 

 specimen with 24 scale rows. 



Ilahitat. — The few specimens known of this species have nearly all 

 come from Okinawa shima. According to a recent paper b}^ Doctor 

 Wall the collector of Mr. Owston obtained not only four specimens 

 in Okinawa shima, but also three in Amami-o-shima, and one m Yaku 

 shima. The latter occurrence is so extraordinary, however, that it 

 would be well to await corroborative evidence, as some mistake in 

 the labeling may be possible. 



As I have stated elsewhere, there is no near relative of tliis species 

 known from Formosa, but as it is allied to the Himalayo-Chinese 

 Tririteresurus monticola, the latter or a related form maybe expected 

 to occur in that island.
