head proceeds a very strong horn-shaped process of 

 the length of several inches, gradually tapering into 

 a slender extremity: the length of this specimen is 

 about four feet and a half, and the breadth about 

 live inches, exclusive of the back fin.

THIS, which is a native of the Indian seas, and 

 which appears also to be occasionally seen in those 

 of Europe, is described by Dr. Bloch from a draw- 

 ing communicated by J. Hawkins, esq. In its 

 general appearance it is much allied to the pre- 

 ceding kinds, but appears to be furnished with two 

 pair of ventral processes, which are of considerable 

 length, and terminate in large, dilated, finny ex- 

 tremities of an oval form ; the back-fin is continued 

 as far as the tail, which, in the figure given by 

 Dr. Bloch, is represented as of the usual form in 

 the generality of fishes, (a circumstance probably 

 owing to a mistake of the draughtsman*.) The 

 colour of this species is silvery, with a blueish cast* 



* I am assured by Mr. Hawkins that this is really the case, 

 the specimen from which the drawing was taken having been 

 defective in that part.
