PALE SNAKK. 



cially towards the head, which is of a lengthened 

 form, white on the top, speckled with black, co- 

 vered with large scales, and marked along each 

 cheek by a broad black band united at the begin- 

 ning of the neck by a transverse bar, from the 

 back of which proceed a pair of abrupt streaks down 

 the sides of the neck : tail moderately slender, ta- 

 pering to a line point : abdomen white : native of 

 South America. In the kind called Xaxahlhua 

 by Seba, figured at pi. 63 of vol. 2. the head is 

 yellow with the black cheek stripes, and the body 

 white, with four narrow lines along the upper 

 part, the two middle ones being black, and the 

 two exterior red : perhaps, after all, these snakes 

 may be no other than varieties of some of the 

 Linnaean lineated species, which are known to 

 vary considerably in their colours, and in the dis- 

 position of their marks.
