animals have been seen in its waters and are still occasionally to 

 be encountered, although the evidence offered is very meagre and the 

 descriptions given of the so-called crocodiles are far from satisfactory. 



The natives describe the crocodile as being much darker in color 

 than the alligator and state that in the crocodile the upper jaw is 

 movable instead of the lower. This latter notion, it may be ob- 

 served, is common throughout this part of the country, and is insisted 

 upon by many hunters, although the basis for the idea is n3t evident. 

 On the other hand, the chief points of scientific distinction between 

 the two animals is never touched upon by those who profess to have 

 seen the crocodile, and even such striking differences as the longer 

 snout and the more active movements of the latter animal appear 

 never to have been noticed. 



Bryant Lee states that crocodiles have been taken in the region 

 around Cow House, but that he has never seen one south of Honey 

 Island. Joe Saunders insists that he has seen crocodiles in a creek 

 flowing into the Suwanee River in Clinch County, while Jackson Lee 

 says that he knows of at least two crocodiles being taken in Billy's 

 Lake. These hunters, when pressed for details, state that the chief 

 distinctive character of the crocodile is the color of its eyes, which 

 they describe as red or orange, and the much darker color of the body. 



These men have spent their lives in the swamp and are remarkably 

 close observers, and it is evident that the form which they have in 

 mind is in some way different from the common alligator, but it 

 seems unlikely that it is Crocodilus americanus. 



II. SNAKES. 



BY A. H. WRIGHT AND S. C. BISHOP. 



No State in the United States has furnished more distinctive and 

 peculiar snakes and no area has received more herpetological atten- 

 tion than Florida, yet none of these numerous ophidian collectors 

 and students has ever entered Okefinokee at Florida's northern 

 border. The nearest approach came about twenty-five years ago 

 in the visit of the ornithologist, Mr. C. F. Batchelder, of Cambridge, 

 Mass. He spent a day or two on Mitchell and Black Jack Islands. 

 To the eastward, at St. Mary's, Ga., and at Fernandina, Fla., he 

 took the following si3ecies: 



Cijclophis wstivus, Osceola doliata doliata, 



Osceola elapsoidea, Ophibolus getulus getulus. 



In Florida, at Gainesville, the snakes secured by James Bell in
