FAMILY GOBIDiE GOBIUS. . 161 



Color. " Surface greenish brown, with seven or eight paler transverse bars over the body 

 " and tail ; fins dark brown, with a bluish shade" (Mitchill). Caudal fin with two or three 

 curved bars. 



Length, 2-0. Depth, 0"3. Breadth of the head, 0'3. 

 Fin rays, D. 6.14; P. 17; V. 12 or 13 ; A. 11 ; C. 19. 



This species must, from the absence of scales, and its indistinctly connected dorsals, form 

 the type of a new genus. It is with some hesitation that I have annexed the synonimes of 

 Bosc and Lacepede, but they evidently point to this or a very closely allied species. It is 

 found rarely in the harbor of New-York. I have seen some specimens an inch long, with the 

 vertical bars quite indistinct. Its known geographical range is at present included between 

 New-York and Charleston.
