 angle of the mouth. Teeth of the upper jaw oblique, scarcely con- 

 stricted near the base ; lower teeth slender, triangular in young ex- 

 amples, lanceolate, with, a broad base in old ones*. Pectoral fin

 p. 32, pi. 1. fig. 2 (head). 



Snout moderately produced, the distance betweeft the mouth and 

 extremity of the snout being nearly equal to the width of the mouth. 

 No labial fold, except a groove at the angle of the mouth. Teeth of 

 the upper jaw scarcely oblique, triangular, serrated; lower teeth 

 slender, lanceolate, not serrated, with a broad base. Pectoral fins 

 shorter than the head, longer than broad, scarcely emarginate. Dorsal 

 fin nearer to the ventrals than to the root of the pectorals. {Blkr.)

* In very young examples the dentition is that of Scoliodon ; then a few den- 

 tieulations appear at the base. The serrature is most perfect in the upper and 

 lower teeth in examples of a length of about 4 feet, in which the lower teeth 

 form a nearly regular narrow triangle. In old examples the serrature is lost 

 again, especially in the lower jaw, in which the teeth are very naiTow, erect, or 

 slightly oblique, standin upon a broad base.
