CARCHARIAS FEROX. 27 



in C. taurus the long teeth are provided with a small cusp at each side of the base. 

 Day's specimen was 12 feet 3 inches in length; he says the species attains a 

 length of 20 feet. 



The localities given are the coasts of Kurrachee and Baluchistan; a speci- 

 men from South Australia is mentioned. 



Giinther mentions others from the Cape seas, and from Tasmania, which are 

 probably of the same species.

Body elongate fusiform; head depressed; snout short, blunted. Nostrils 

 near the mouth; anterior valve, small, triangular. Eye small, above the mid 

 length of the mouth. Mouth large, labial folds on the lower jaw, as in C. taurus. 

 Teeth with a strong lanceolate cusp at the base of which on each side there are 

 two denticles, in ft rows; anterior tooth of each upper jaw small, second and 

 third large, fourth to seventh small, eighth and following large but gradually 

 diminishing in size toward the angles of the mouth; anterior tooth of each 

 lower jaw small, second larger, third largest and followed by similar teeth gradu- 

 ally reduced in size to the small compressed chisel-shaped teeth at the angles. 

 Spiracles small. Gill openings large, width about equal length of snout, hind- 

 most in front of the pectoral. Pectorals moderate, longer than broad, hind 

 margin nearly straight. Dorsal origin above the inner angle of the pectoral 

 about the middle of the trunk, excluding the caudal fin, extremity reaching 

 little behind a vertical from the origin of the ventrals, size greater than that of 

 the second dorsal. Origin of second dorsal behind the ends of the ventrals. 

 Anal smaller than second dorsal and origin nearly below the middle of the latter's 

 base. Caudal less than a third of the total length; subcaudal followed by a 

 shallow notch, lobe somewhat produced. 



Back and sides ashy brown; lower surfaces lighter.
