12. I have seen two new species of the Rattle- Snake, 

 of a tremendous size : one 6 feet long, IIttt inches in 

 circumference, ^ith a row of A\'hite lined rhombi along 

 the back. I have ventured to name this Crotalus 

 rhombiferus. Its skin is black---151 scuta on the belly, 

 25 on the tail. The other has a yellowish skin, with 

 dark zig-zag belts — 170 scuta on the belly, 25 caudal. 



1 was puzzled for a name, but called it Crotalus zetazo- 

 nae, until Dr. B***** names it. The length is 6 feet 



2 inches : ambit 5\ inches, I think. 



We have two dwarf kinds of Crotalus, whose bite, 

 as that of the others, is mortal. I think them non-de- 

 scripts. One is yellow, with dark narrow zoni, and has 

 a dark fillet round the head, above the eyes. The other 

 is blackish, with rhomboid, dark lined transverse figures 

 on the back.
