OF 
CROTALOPHORUS —Gray. 
Genus CroratopHorus.—Cuaracters. Head large, triangular, rounded in 
front, covered with plates above; a deep pit between the eye and nostril; rattles 
few in number, and not well developed; plates on the abdomen; plates mostly 
single, few, bifid under the tail. 
Remarks. This genus was first established by Mr. Gray, and makes a very 
natural transition from Crotalus to Trigonocephalus, having the rattles of one at 
the tail, and the plates on the head of the other genus. Fitzinger calls it Caudi- 
sona, a name more applicable to Crotalus, as it makes but a feeble noise at best 
with its rattle, and often none at all. 
CROTALOPHORUS MILIARIUS.—Linnzus. 
Plate IV. 
Cuaracters. Head large, triangular, rounded in front; covered anteriorly and 
on the vertex with plates, posteriorly with scales; a pit between the eye and 
nostril; upper jaw with poisonous fangs; body above dark grey, with a vertebral 
brownish-red line, interrupted by a row of sub-quadrate black spots, margined 
with yellow, and a double series of black spots on each side, the upper larger, but 
less distinct. Caud. Pl. 30.
