 minences; it is not depressed, or emarginate or seiTated; the notch in the caudal shield 

 small, shallow. Sternum rounded on the sides, not keeled, ' nearly as broad between the 

 front as between the hind incisions, the breadth between them being one-half of its length ; 

 it is truncated anteriorly, and its posterior notch is obtusangular. 



Plates. — The areolae are finely granular, situated on, or very near to, the posterior margins 

 of the plates; those of the vertebral and costal plates are divided into two by the ridges. 

 The costal ridges are very narrow, almost linear, but very distinct ; they run at an equal 

 distance from the vertebral ridge and from the lateral edge of the shell. The areolae of the 

 sternal plates are scarcely perceptible. Nuchal plate very short, broader than long ; verte- 

 brals broader than long, the last broader than the caudal, which is divided into two. All 

 the marginal plates very narrow. Gulars longer than broad, the suture between the post- 

 gulars being very short. Pectoral, abdominal, and prseanal of nearly equal length, or the 

 pectoral a Httle shorter than the others ; sternal portion of the abdominal square. Suture 

 between the anals longer than their posterior margin. 



Head covered with undivided skin ; upper jaw not denticulated. Tail longer than the head. 

 Toes moderately webbed. 



Colour. — The upper shell and the soft parts are brownish ; each sternal plate with a large 

 dai'k-brown blotch in the centre ; two oblique yellow lines behind the eye, on the temple ; 

 neck with two longitudinal yellow lines on each side, and with one along the middle. 



This small Emys (from 3 to 4 inches long) is a native of Southern China and Cochinchina.

 is said to come from India.
