and generally the third also pointed at their junction. Pectorals sub- 

 quadrangular. Caudal divided into two; claws 5 before, 4 behind, feet

Nuchal plate short, broadish, sub-quadrangular, broadest behind. 

 Vertebrals raised along their raedian line in a ridge, which is most 

 distinct on the middle of the back, terminating in a nodose promi- 

 nence on the third and sometimes on the second vertebral. The first 

 vertebral is sub-quadrangular; the second and third are rounded 

 behind and narrowed, longer by half than broad ; the fourth cuneiform, 

 tapering anteriorly ; the fifth more than twice as broad as the 

 caudals, Caudals much longer than broad, separated by a groove 

 and a very small notch. Hind margin of the upper shell distinctly 

 serrated. Gulars longer than broad, the suture between them being 

 shorter than that between the post-gulars. Pectorals shorter than 

 post-gulars, abdominals or pra3-anals. Head covered with undivided 

 skin. Jaws finely denticulated. Upper jaw not emarginate anteriorly. 

 Tail rather shorter than the head. Feet broadly webbed. Front part 

 of the fore los: and base of the fifth toe with larsfe imbricate scales. 

 Colour above, brown with a black vertebral line. Sternal plates 

 blackish brown, margined with yellow. Grows to 8j inches.

Shell ovate, slightly depressed, wdth a distinct vertebral ridge from 

 the nuchal to the caudal plate, rising into an elongate prominence on 

 the back of the third plate. Sternum flat, its width between the 

 inguinal incisions being rather more than that between the axillary, and 

 rather less than one-half its length. Upper shell slightly serrated 

 posteriorly ; nuchal plate small, triangular. The first vertebral is bell- 

 shaped, scarcely longer than broad, and broadest behind ; the second 

 sub-quadrangular; the third rectangular, oblong, two-thirds as broad 

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

 Gulars considerably longer than broad. The posterior margins of the 

 post-gulars are strongly convex, forming a deep curve. Abdominals 

 nearly as large as post-gulars and pectorals together. Colour above 

 pale yellowish olive; vertebral keel blackish, lower parts black, each 

 plate with yellow margins. Fore legs covered in front with large im- 

 bricate scales rather obliquely arranged and with roundish smaller 

 ones between. Hind legs on the outer side with smaller scales, but 

 apparently more horny. Grows to 9 inches. 



Hah. — Common in the Indus, extending to the Punjab, where it is 

 found in the Sutlej and Chenab Rivers. Affects the Ganges also.
