154 NEW-YORK FAUNA. 



Color. This is extremely fugacious. I was fortunate in being able to have a drawing made 

 from a living specimen, caught near my house, on the northern coast of Long Island. The 

 general color, as will be seen by reference to the plate, is greyish, with a series of oval ver- 

 tical dusky rings along the sides. Abdomen greyish white, tinged with yellow. Irides 

 white. Dorsal fin grey, with fourteen black vertical distant stripes. Pectorals and caudal 

 yellow. Anal fin greenish grey, with alternate darker stripes. 



Length, 4-5. Depth, 0'5. 



Fin rays, D. 78 ; P. 12 ; V. 1 ; A. 2.36; C. 16 |. 



In another specimen, D. 75 ; P. 11 ; V. 1 . A. 2.40 ; C. 18. 



This pretty little species is frequently found among rocks along the sea-shore, and in the 

 mud. It swims with great rapidity, although its usual habit is that of creeping slowly among 

 rocks, in which it is probably assisted by its spiny ventrals. It abounds in Robyn's reef in 

 the harbor of New- York. The description given by Mitchill, incomplete as it is, I have 

 reason to know, applies to our species. It resembles the G. vulgaris of Yarrel (Vol. 1, p. 

 239) ; but from the above description, is evidently distinct from that species. Its present 

 known limits are from Massachusetts to New- York, but it probably ranges still farther north.
