36 CHELONIA. 



gulars and pectorals are much directed backwards, forming together an angle of about 1 30°. 

 Pectorals shorter than postgulars, abdominals, and prteanals : the suture between the anals is 

 longer than their hind margins, which are separated by a semicii'cular notch. 



The soft parts are similar to those of P. tentoria. 



The shell is uniform homy brown above, the ridge lighter, the nodose prominences darker. 

 Lower parts uniform yellowish, with the exception of the marginal plates, each of which has 

 a brown blotch on its lower side. No markings are visible on the soft parts in the single 

 stuffed example known. 



I am indebted for the knowledge of this species to Mr. F. Moore, Custos of the East India 

 Collection, who kindly allowed me to examine the Reptiles under his charge. It is founded 

 on a well-preserved, stuffed example, the shell of which is 8 inches long. No other record 

 has been kept of this specimen, except that it had been sent by Mr. M'Clelland; several 

 other Tortoises sent by the same gentleman, at the same time, are Bengal species. 



Pangshura smithii. (Figure, see p. 2.) 



Batagur smithii, Gray, MS. 



Form. — Shell ovate, slightly depressed, with a very distinct vertebral ridge, which extends 

 from the nuchal to the caudal plate, and terminates in an elongate prominence on the 

 third plate. The sternum is flat, its width between the inguinal incisions being rather more 

 than that between the axillary, and rather less than one-half of its length ; it is rounded in 

 front. Upper shell slightly serrated posteriorly. 



Plates. — Nuchal plate small, rather longer than broad, broader behind than in front. The 

 first vertebral shield is bell-shaped, scarcely longer than broad, and broadest behind ; the 

 second is subquadrangular, much broader than long; the third is rectangular, oblong, two- 

 thirds as broad as long; the fourth is much elongate, pear-shaped, tapering anteriorly. 

 Gulars considerably longer than broad, the suture between them being two-thirds of that 

 between the postgulars. The posterior margms of the postgulars are strongly convex, forming 

 a deep curve. The abdominals are nearly as large as the postgulars and pectorals together, 

 the latter being scarcely longer than the anals. 



The soft parts do not show any peculiarity. The upper shell is yellowish, with a part of 

 the vertebral keel blackish. The lower parts are blackish, each plate with yellowish margin. 



The typical specimen of this species is stuffed ; shell 7 inches long, and perfectly ossified ; 

 it is not known from what country it came, but it probably occurs in continental India, like 

 its congeners. A smaller example, from the Eiver Chenab (Punjab), has been referred to 

 this species by Dr. Gray, but it differs in several important points ; and the plates being 

 deformed in many places, I hesitate to give a description of it.
