legs, and front of tail, brick-colored patches. Lines fade out on tail 

 which is almost entirely gray a short distance from its base. A brown- 

 ish-gray line on posterior side of hind leg, leaving a white one between 

 it and color above. It extends along lower side of tail w^here it is blue- 

 green, and though continued a good distance back is not well defined. 

 Toes and soles of feet pale brownish flesh-color. 



Key West, Boca Chica, Big Pine, Knight, Vaca and Grassy Keys. 

 The above notes are from an example from the former locality. They 

 were abundant on most Keys, where they were seen running swiftly 

 through the grass. They soon hide in holes or among rocks. About 

 the lagoon on Key West I found them most common under low grassy 

 vegetation where numerous insects, such as small grasshoppers, were 

 seen. 



IGUANIDiE. 



96. Anolis principalis (Linnaus). Lion. 



Key West, Boca Chica, Marquesas, Big Pine, No Name, Vaca, 

 Grassy and Summerland Keys. Many bright green examples were 

 seen on Key West among grasses and other green vegetation, from 

 which they are distinguished with difficulty. Those on the ground, 

 or on brown sticks, etc., were brown in color. I never saw the animal

 more easily captured than the other species. 



CROCODILID^. 



97. Alligator mississippiensis (Daudin). Alligator. 



Reported from several pools we saw on Little Pine Key, thougli I 

 did not see any example during our stay. They were also reportefl 

 from pools on Summerland Key, and were said to occasionally reach 

 six feet in length. 



DERMOOHELYDID^ . 



98. Dermoclielys coriaoea (Vaiuk-lli). Trunk Back. 



Frequently taken about the Keys. Several shells were seen about 

 Key West. 



CHELONIID^. 



99. Thalassochelys caretta (Linnaeus). Logger Head Turtle. Logger Head. 



Reported as al^undant in the past and still frequently taken. It, 

 like both of the following species, is much sought after, and bids fair 

 to become exterminated in a short time if the ruthless depredations of 

 the turtle-fisher are not speedily checked. These animals, all of which
