The Louisianian district possesses the peculiarities of the austroripa- 

 rian fauna already pointed out, minus those of Florida and Texas. Of 

 Mammalia, the genera J. Zees, j\IustelajJaciilus,Arctomys,Fiber,Sin{i Condy- 

 lura are wanting, as well as the red-squirrel, Canada lynx, gray-rabbit, 

 etc. Its most remarkable birds are the nonpareil finch, ivory -billed wood- 

 pecker, parrckeet, etc., while its Flaps falvius, or corr.l-snake, is one of the 

 most beautiful of the order. A large and dangerous rattlesnake is also 

 confined to it, viz, Caudisona adamantea, and the well-known moccasin 

 Ancistrodon piscivorus does not range outside of its boundaries. A 

 species of the West Indian Dromicus (serpents) has been found on the 

 Atlantic coast.
