Snout obtusely rounded. Teeth of moderate size, |^, triangular, 

 scarcely oblique, serrated, subeqzial in aize and form in both jaws. 

 The first dorsal commences immediately behind the base of the

The specimens described by Blocker (Verh. Bat. Gen. xxiv. Flag, 

 p. 41, and Nat. Tyds. Ned. Ind. vi. p. 507) and by Dumeril (Elas- 

 mobr. p. 361, from a drawing !) cannot belong to the species described 

 by Miiller and Henle. We have received one of them from Dr. 

 Blocker ; it is a new-born individual, in which the teeth of the 

 lower jaw have the narrow lanceolate shape, as found in C. lamia, 

 being very different from those of C. amboinensis. I cannot refer 

 this example with certainty to any of the species named by Miiller 

 and Henle.

Snout of moderate length, rounded, the distance between the 

 mouth and the extremity of the snout being equal to the distance 

 between the inner angles of the nostrils. No labial fold, beside a 

 groove at the angle of the mouth. Teeth of moderate size, p^ ; the 

 upper regularly triangular, without notch on the posterior margin, 

 both margins being distinctly serrated. Lower teeth narrowed, with 

 a broad, two-rooted base, very finely serrated on both margins. 

 Pectoral fin very large and long, extending in young examples beyond 

 the dorsal, and in adult nearly to its end. The first dorsal large 

 and high, its depth being equal to the depth of the body. The second
