angle of the mouth. Nostrils in the front half of the distance 

 between the end of the snout and the mouth. Gill-openings wider 

 than the orbit. Teeth twenty-seven to thirty in each jaw, all 

 serrated; the upper almost triangular, their outer edge with a 

 notch, very distinct in the immature, but becoming almost lost 

 with age ; those in the lower jaw narrow, erect, and having broad 

 bases. Fins pectoral elongated, falciform, and extending to 

 beneath the middle of the first dorsal ; its internal margin % of 

 the length of its outer. Origin of the first dorsal slightly posterior 

 to the hind edge of the base of the pectoral, its base not extending 

 to above the ventral. The second dorsal of about the same size as 

 the anal, the latter nearer to the caudal than to the ventral. Length 

 of the caudal 3| in the total length. Scales small and with rough 

 edges ; they are hardly above half the size of those in C. melanop- 

 terus. Colour grey superiorly, becoming dull white beneath. 

 Fins grey, the pectoral, ventral, and anal with white edges ; pos- 

 terior portion of caudal rather dark. 



Hcib. Seas of India to Japan, ascending rivers to above tidal 

 influence. It is the commonest form along the Burmese coasts and 

 attains at least nine feet in length. 



This is one of the most ferocious among Indian sharks, and 

 frequently attacks bathers even in the Hooghly at Calcutta, where 

 it is so dreaded that a reward is offered for its destruction.

Length of the preoral portion of the snout two thirds the width 

 of the mouth and considerably less than the distance between the 

 eye and the first gill-opening ; a very short groove at the angle of 

 the jaws. Nostrils nearer to the extremity of the snout than to 

 the end of the mouth. Snout rounded and very obtuse. Teeth 

 !^|(|i), the upper broad, flattened, oblique, with a very slight 

 notch or rather concavity on the outer side and serrated ; the 

 lower much narrower, pointed, on a broad base and also serrated, 

 these serrations being generally minute, sometimes only on one 

 side of the tooth, and occasionally wanting, especially in the lower 

 jaw. Fins pectoral falciform, extending to beneath the middle 

 or even hind edge of the base of the dorsal, its outer edge three 

 times as long as its inner one. Base of first dorsal a little nearer 

 the pectoral than its posterior end is to the ventral. Second 

 dorsal opposite and similar to the anal. Length of caudal 3| to 4| 

 in the total length. Scales comparatively large, lineated, but with 

 almost smooth edges. Colour brown or bluish grey superiorly,
