308 NEW-YORK FAUNA. 



Color, of a fresh specimen just from the water. Slate brown above ; lighter beneath. A 

 broad black band extends from the angle of the mouth to the tail. The lateral line is placed 

 on the upper margin of this longitudinal band, where it may be indistinctly traced. Along 

 the back, a series of triangular dark colored marks like an inverted letter \. Beneath, mot- 

 tled slate and whitish. Irides silvery; pupils black. Pectorals and vcntrals edged with 

 white ; dorsal and caudal with a white border on their anterior rays, broad on the first ray, 

 and gradually diminishing and becoming effaced on the posterior rays. Tips of the caudal 

 broadly edged with white.

This interesting species is not uncommon on the coast of Long island, and has been seve- 

 ral times brought to me by those who took it in ordinary seines. This circumstance would 

 seem to indicate that it is not as constantly attached to other species as is commonly supposed. 

 From being often found sticking to the shark, it is called in this vicinity the Shark-sucker. 

 I have seen a specimen which had ascended a considerable distance up the Hudson river. It 

 appears most commonly in July and August. The species of this geftius have furnished ro- 

 mance writers, under the name of naturalists, with an abundance of marvellous anecdotes, 

 which are now generally discredited. All the species are natives of the tropical seas, and 

 they are only to be considered in the light of accidental visitors on our coast.
