Description. — This species closely resembles the preceding. 

 Its carapace, however, is never tri-carinated, but exhibits 

 along its centre a single raised line, much more elevated 

 in its hinder than in its anterior portion ; this gradually 

 disappears with advancing age : the surface, moreover, 

 above the eyes, instead of being flat or slightly hollowed, 

 is somewhat convex. The markings of the carapace differ 

 considerably in the two species. In the present one, the 

 yellow network is altogether wanting, while in the centre 

 of each plate of the disk is an orange spot surrounded with 

 black, and on its other parts two or three of a less regular 

 form ; the plates of the margin are also spotted with 

 yellow, varying in extent and brightness of hue in dif- 

 ferent individuals. The head is uniform olive-green, with- 

 out a trace of yellow lines. The longitudinal lines on the 

 neck, instead of being yellow, edged with black, as in the 

 E. Caspica, are orange, and without a black border. The 

 sternum is brown, with a broad, waved, pale yellow line 

 along the margin, extending sometimes over the centre, 

 and following the sutures of the plates. In animals of 

 every age, a deep black, longitudinal band is observed on 

 each lateral prolongation of the plastron. 



Its size is less than that of the foregoing species ; the 

 total length of a small specimen given in the ' Erpetologie 

 Generale,' being 16 centimetres, about 6J inches. 



It is found in Europe, in Spain only, but is common on 

 the opposite coast of Africa, and has been obtained at 

 Algiers.
