120 EMYS CONCINNA. 



palmated toes, of which only the four internal are furnished with nails. The tail 

 is moderately long, and broad at the root, but soon becomes slender. 



Colour. The shell is dusky, varied with differently formed and differently 

 disposed lines of yellow; those on the lateral plates are somewhat reticulate, and 

 the spaces formed by them are frequently filled with short lines of yellow, all more 

 or less confluent. The marginal plates are all marked either with a straight line 

 or a sub-quadrangle of yellow. The sternum is yellow, as well as the marginal 

 plates below, each having a large black spot at the jimction; the Avings have a 

 dark longitudinal line. 



The head and neck are black, striped with red or orange; the stripe on the neck 

 bifurcates on the fore part, one branch rumiing to the eye, the other to the chin, 

 so that the jaw is embraced between tliem; the stripe on the chin bifurcates 

 posteriorly a short distance from its origin, and running along the throat, includes 

 a shorter stripe between its branches. The jaws are striped with yellow. The 

 eyes are yellow, with a broad black stripe through the middle. The anterior 

 extremities arc dusky, striped with red or orange above, and below Avith tlu'ee 

 transverse and two horizontal lines of the same colour. The posterior are dusky, 

 obscurely striped with red above, and irregularly marked with orange and yellow 

 beneath. The tail is striped with red above and yellow below. 



Dimensions. Length, 85 inches; elevation, 31 inches. 



Geographical Distribution. This species is found in the Savannah and 

 Congaree rivers, where their beds are rocky, and arc not seen below Augusta on 

 the one, nor Columbia on the other river. 



General Remarks. This is another fine species of Emys, first observed and 

 described by Leconte, and as I have never yet had an opportunity of examining 

 the entire animal, I have in this place done no more than reproduce his observa- 

 tions, and to him I am indebted for the beautiful plate that accompanies this
