be black with very inconspicuous lighter spots on the lateral portions 

 of each scale. One of the two Koh Chang specimens (72149) is un- 

 like all the others in having black spots in the centers of the labial 

 scales. This snake likewise is without loreal plates. 



In all specimens the scale preceding the anal plate was divided like 

 it. The maximum number of subcaudals listed by Boulenger is 138; 

 my series raises the number slightly, as two of the snakes have 140 

 each and one specimen has 141. The specimens from Bandon 

 (67495-7) were collected by Mr. K. HavmoUer. The young speci- 

 men, 70301, was captured in the Hotel Royal at Bangkok.

As the sea snakes have just been monographed by Dr. Malcolm 

 Smith, I make no further notes on the species included in Dr. Hugh 

 M. Smith's collection other than to list them with data. Many of the 

 identifications were made by Dr. Malcolm Smith at the United States 

 National Museum.
