THE ROSY BOA 



Lichanura rosea fusca, (Cope) 



Body stout, tail short, blunt and slightly prehensile. Head 

 rather long and but slightly distinct from the neck. Eye large, 

 with elliptical (cat-like) pupil and surrounded with a ring of 

 7to lo scales. Several pairs of shields near the snout; remainder

THE THREE-LINED BOA 

 Lichanura trivirgata, (Cope) 



Eye larger than that of the preceding. 



Colouration. — Pale yellow or brownish, with three vividly 

 defined dark brown stripes or bands, extending from the snout 

 to the end of the tail; the central of these bands is four scales 

 wide and those on each side of it are five scales wide; the bands 

 are separated by spaces three and a half scales in width. 



Distribution. — The original specimens were found in swamps 

 among the mountains near Cape St. Lucas, Lower California. 



THE RUBBER BOA — SILVER SNAKE— TWO-HEADED 



SNAKE — WORM SNAKE 



Charina bottce* (Blainville) 



Size moderate. Form very stout. The tail is almost as 



blunt as the head, hence one of the popular names — two-headed 



* A single specimen was described by Prof. Cope as C. brachyops; it 

 differs from bottcB in the absence of a loreal plate, bringing the postnasal 

 in contact with the preocidar and in the rear prefrontal forming a part of 

 the orbit.
