34 CHELONIA. 



broad orange converging streaks, neck with numerous yellowish longitudinal lines ; legs with 

 yellowish dots. The lower parts of the shell yellow, with large blackish-brown spots. 



The shell of the largest specimen I have seen is 5 inches long ; specimens 6 inches long 

 are on record.

The Dui'a is very similar to the Pangshure, from which it may be readily distinguished by 

 its shell, which is somewhat more depressed, its greatest depth being less than one-half of 

 its length. 



Plates. — Nuchal plate short, broadish, subquadrangular, broadest behind. The vertebral 

 plates are raised along their median line into a ridge, which is most distinct on the middle 

 of the back, terminating in a nodose prominence on the third, and sometimes on the second 

 vertebral. The first vertebral is subquadrangular, as broad posteriorly as anteriorly ; the 

 second and third are rounded behind and narrowed; the fourth is cuneiform, tapering 

 anteriorly ; the fifth more than twice as broad as the caudals. Caudals much longer than 

 broad, separated by a groove and by a very small notch. Hind margin of the upper shell 

 distinctly serrated. Sternum flat, keeled on the sides, rather elongate, its width between the 

 inguinal incisions being less than one-half of its length. Gulars longer than broad, the 

 suture between them being shorter than that between the postgulars. Pectorals shorter 

 than postgulars, abdominals, or praeanals; the suture between the anals is longer than 

 their posterior margins, which meet at an obtuse angle. 



Head covered with undivided skin ; jaws finely denticulated, the upper jaw not emarginate 

 anteriorly. Tail rather shorter than the head. Feet broadly webbed ; front part of the fore 

 leg and base of the fifth toe with large imbricate scales ; claws of moderate size. 



Colour. — The upper shell is uniform brovra ; the sternal plates blackish broion with yellow 

 margins. 



The only specimen known in European collections* was brought from the Deccan by 

 Colonel Sykes, and is 6^ inches long ; it does not appear to be adult, as the shell is not 

 entirely ossified. A second specimen, of nearly the same size, was obtained at the Indus by 

 Sir A. Bumes, and is now in the Museum of the Asiatic Society at Calcutta. Mr. Blyth 

 (Journ. As. Soc. Beng. xxii. 1854, p. 643) mentions that he has met with one young specimen 



* The two half-grown specimens mentioned by Dr. Gray in the ' Catalogue of Shield Reptiles ' are 

 probably the young of Batagur dhonyoka.
