 One sp. S. America, ? 



210. ?S. poecilonotus Othr. 



One sp. Caraccas, Mr. W. G. Boulton. 



Our specimen differs from Gunther's type, in having the carination of the 

 dorsal scales quite weak, the lateral borders of the vertical plate but little 

 concave, the last two upper labials confluent on both sides, and nearly all the 

 scales on the anterior half of the body with yellow centres. 



211. S. melanurus Dum. Bibr. 



One sp. Panama, Drs. Gallaer & Le Conte. 



One sp. Caraccas, Mr. Ashmead. 



This species is certainly very nearly allied to the S. corais, but we cannot 

 at present agree with Giinther in regarding it as the young of that species. 

 The corals is stouter in form, and does not probably exhibit a black tail, 

 and black lines upon the neck, at any age. 



212. S. corais Dum. # Bibr. Coluber coral's Cuvier. 



One sp. (very large) Surinam, Dr. Hering. 



One sp. (half grown) " " 



One sp. (very young) " Dr. Colhoun. 



In the young specimen there are forty-one pairs of oblique dark grey cross- 

 bands on the body above. 



213. S. erebennus nobis. Coluber obsoletus Holbrook, not Say. Georgia 

 obsoleta Bd. & Grd. 



Independently of color, this species differs from the corais in the shorter 

 loreal, longer inferior postocular, and longer external longitudinal border of 

 occipital plate. The fifth and seventh superior labials are entirely separated 

 by the sixth. 

 One sp. Eagle Pass, Texas, Smithsonian Inst. 



214. S. Couperi nobis. Coluber Couperi Holbrook. Georgia CouperiBA.k Gird. 

 In this noble species there is one superior labial less than in S. corais : 



the fifth and seventh labial plates form a suture above the sixth, as in that serpent. 

 One sp. Georgia, Dr. Holbrook.
