80 GENUS LISSA. 



tured, linear, not elongated- lingers nearly as long as the 

 hand, punctured above, with an imprtbsed punctured 

 line each side, and white tip, may teeth within; terminal 

 joint of the abdomen transversely eliptical. 



Length one inch and three fourths, breadth one inch 

 and one filth. 



This curious, and, as I believe, new species, was 

 found by Mr. C. A. Le Sueur, on the coast of Long 

 Island, and kindly communicated by him to the author. 

 It is a male. Upon the body, rostrum, and feet are a num- 

 ber of hooked, short, stout, yellowish hairs, arising from 

 pores, andcurving in various directions, but generally back- 

 wards? they are not unlike in appearance to a young vege- 

 table production: these arrest and entangle the loose por- 

 tions of fucus, or other marine plants, amongst which ihese 

 animals are found, so as to conceal them from their prey, 

 that they ma/ the more readily surpri;:.e it; so completely 

 are they sometimes covered as to appear like a moving 

 mass of various kinds of marine plants, no portion what- 

 ever of the animal being visible; this habit is not peculiar 

 to the individual here described, but is most probably 

 common to the species of this and the cognate genera, such 

 as the genus Pisa, Mr. Le Sueur informs me, that he 

 has seen Crustacea in New Holland, with the same habit; 

 the fucus, in some instances, was so much entangled with 

 the hooks, feet, &cc., as to be with difficulty removed*
