Harlan, the latter gentleman appears to pay particular attention 

 to this class of animals, and has given some interesting remarks 

 on their internal organization, which will be inserted amongst 

 the Zoological Notices in our next number. 



1. On the Fresh Water and Land Tortoises of the United 

 States. By Thomas Say, .p. 203. 



In this paper Mr. Say enumerates 15 species, one of which is 

 new; and he has named, but not characterized two new genera^ 

 one for the Box Tortoise, under the name of Cistula, but this 

 has been long established in the works of Merrem (which the 

 American naturalists do not appear to know) under the name of 

 Terrapena, and the other Chelonura, for the Testudo Serpentina 

 of Shmv. 



To the description of the species he has added some inter- 

 esting remarks, relative to the habits of the animals, and the use 

 made of them by the Americans. 



The new species is Emys biguttata, Say. Shell oblong, oval, 

 slightly contracted in the middle of each side, anterior marginal 

 scuta, very narrow, linear, occiput with two very large fulvous 

 spots ; upper jaw naked ; lower acute; tail rather long, simple. 

 Length 4, breadth 3 inches. 



2. Description of Three New Species of Coluber, inhabiting 

 the United States. By T. Say, p. 237. • 



Coluber (Bm(enus. Above brownish or blackish, beneath bright 

 red, tail short, with an abrupt solid conic tip. Pensylvania. 

 Plates 124—134, scales 24—38. Length 10 inches, tail 1-^ 

 inch. Var. a dark slate colour above. 



C. rigidus. Dark fuscous or blackish ; beneath the yellow, 

 with two black hues. Southern States. Plates HI, scales 51.

 neath yellow, with four blackish lines. Pensylvania. Plates 

 142, 143, scales 70—73. Length 10, tail2x inches. 



The rest of the papers are by Dr. Harlan, the first of which is 

 a " Notice of the Plesiosaurus, and other Fossil Reliquia, from 

 the State of New Jersey, p. 232, where the author points out a 

 new species of this interesting genns, and the three remainder 

 are descriptions of the following new species of reptiles, two of 

 which belong to a new genus, under the name of Cyclura, which 

 was noticed in the last number, where it should have been 

 placed directly after Uromastrix, 



Cyclura carinata, n. s, t. 15. Crown of the teeth dentated, 

 infra orbitar ridge with a row of horny scales ; dorsal crest ; 

 warty between the scapula and over the sternum ; scales of the . 

 body uniform, square, small, slightly imbricate, unarmed; scales 

 of the legs and feet ending in minute spines ; tail above keeled, 

 middle slightly compressed, spiny bands ending four inches .
