 Abdominal scuta 152, subcaudal scales 135. 



A RATHER small species : length about a foot 

 and half or two feet: colour bright blue, paler 

 beneath: scales, according to LinnjEus, edged with 

 white, and the tail, which is slender and sharp- 

 pointed, marked beneath by a blueish suture : 

 the head rather large, somewhat angulated, ovate- 

 oblong, and obtuse: colour sometimes blueish 

 green : native of Surinam, and said to be a poi- 

 sonous species. This snake, being avowedly a 

 native of America, is not very happily named by 

 Linnaeus ; the Dipsas of the ancients being an 

 African Serpent.
