MEMOIRS OF THE CARNEGIE MUSEUM 



Genus Rhinostoma Dumeril & Bibron. 



72. Rhinostoma guianense (Troschel).

p. 653. 

 Rhinostoma guianense Boulenger, Cat. Snakes, III, 1896, p. 114. 



There are thirteen examples of this species in the Museum of which it may 

 be confidently asserted that they were all secured in Colombia by Mr. and Mrs. 

 H. H. Smith, when engaged in collecting in that part of the world. All the speci- 

 mens which have locality labels attached came from Bonda, and the dates of those 

 upon which there are records of the time of capture show that they were taken from 

 April to the first week in September. 



Nos. 211, 212, 1857, and 1858 are of the light-colored variety with a dark brown 

 collar on the nape.
