GENERA OF EMYDOID.E.

gia.^ I have received specimens from Wilmington, North Carolina, throngh Mr. 

 S. T. Abert ; and from Savannah, Georgia, through Dr. W. B. Daniell. I am, how- 

 ever, indebted for the largest numbers to Dr. Ilolbrook. Professor Baird has also 

 sent me many young from Savannah. The young are represented PI. 2, fig. IS- 

 IS. I have never been able to obtain its eggs. It is easily distinguished by its 

 broad outline and great height ; keeled along the back, coarsely tuberculated and 

 rugose all over the shield, and deeply notched behind. Thei'e is a broad, trans- 

 verse, light-yellow band across the neck, behind the eye. 



Traciiemys TiioosTri, Ag? In the Western States, from Missouri and Illinois to 

 Tennessee and Louisiana. All the specimens I have seen were sent to me by 

 Mr. G. Stolley, from the Osage River, Missouri ; by Dr. Watson, from Quincy, Illi- 

 nois ; and by Professor Wailes, from Wasliington, Mississippi. Dr. Holbrook men- 

 tions it from Tennessee. It represents, in the valley of the Mississippi, the 

 Trachemys scabra of the southern Atlantic States, and differs from it h\ its 

 more elongated and flattened form, the absence of a median keel, the less coarse 

 tubercles and rugosities of the shield, the less marked notches of the hind mar- 

 gin, the dark, mottled neck, and the total absence of longitudinal and transverse 

 bands upon the neck. I have seen neither the young nor the eggs. 



Traciiemys elegans, Ag? This species is easily recognized by its smoothness 

 and flatness, and the bright blood-red longitudinal band which extends on each 

 side of the neck. It is not as broad as Trachemys scabra. Its geogi'aphical 

 distribution is very remarkable. It is found from the Upper Missouri to Texas ; 

 Init it does not extend to the eastward beyond the lower course of the Ohio. 

 I have received specimens from the Osage River and from Texas, through Mr. G. 

 Stolley ; from Burlington, Iowa, through Dr. J. Ranch ; from Quincy, Illinois, through 

 Dr. Watson ; fi'om Mississippi and Louisiana, through Mr. W. Sargent, Professor Wailes, 

 and Dr. Benedict; and from the Yellow Stone, one of the head waters of the Mis- 

 souri, from the neighborhood of San Antonio, from Matamoras, from the Brazos, 



name. Tliis ciroumstancc removes a part of the con- 

 fusion introiliiccil in the synonymy of our Turtles, in 

 the application of the name of serrata to different 

 species. Testudo serrata, Pen., is Chelydra serpenti- 

 na; Testudo (Emys) serrata, SaijAwiS. Gniij. is Ptyeh- 

 emys rugosa ; Testudo serrata, Baud., is Trachemys 

 scabra ; Testudo scabra, Shaw, is Emys trijuga, Seine. 



' Dnnieril erroneously ([uotes New York among 

 the localities where it occurs. Emys vittala, Gr., does 

 not differ si)eeilically. 



- The first and only complete description is that 



of Dr. Ilolbrook, N. Am. Ilcrp., vol. 1. p. 1 2.'?. pi. 20. 

 'J'emminck and Sehlegel have confounded it with the 

 preceding species. 



* First described by Prince Max. von Neu-Wied 

 as Emys elep;ans (Keise Xord-Anier., vol. 1. p. 213). 

 Dr. Ilolbrook has described and figured it under the 

 name of Emys cumberlandensis, N. Am. Ilerp., p. 

 115, pi. IS. Gray gives it the name of Emys Hol- 

 brookii. in the Cat. Brit. JIus., 1844, p 23. Pro- 

 fessor Wailes mentions it, in his Geol. Kep.. under 

 the name of Emys Terrapin.
