THE CRUSTACEA OF NEW JERSEY. 287 



twelve joints, extends one or two joints beyond first antennae, 

 last four joints very slender and gradually diminishing- in size 

 and length. Maxilliped with palp of two joints. Mandible with 

 palp of three joints. Thorax widest at fifth and sixth segments, 

 which also longer than others. Hind lateral angles of three 

 last segments acutely produced, and extend beyond epimera. 

 Latter distinct on all segments, except first. First three small, 

 first two with hind edges rounded. Last four acutely produced, 

 epimera extending to hind edges of segments, but not to end of 

 hind lateral angles in last three segments. All segments of ab- 

 domen distinct, sixth or terminal rounded behind. Inner 

 branch of uropoda broad, end obliquely truncate and extends 

 little beyond tip of terminal abdominal segment. Outer branch 

 of uropod one-fourth longer than inner branch, slightly nar- 

 rower, and produced to narrow rounded end. Legs all pre- 

 hensile, with long curved dactyls. Color brownish or olivaceous, 

 with two narrow lengthwise bands of paler tint, separated by 

 median dark line, and both usually more distinct on head and 

 telson. Reaches 25 mm. in length. 



Remarks. — ^This species was previously only known from 

 Wood's Holl and Vineyard Sound, if Nerocila lanceolata (Say) 

 is really distinct, as contended. If the latter proves identical, 

 however, the southern range would extend to Georgia. At present 

 Nerocila nuinda Harger is now known for the first time south 

 of New England, as well as an addition to the fauna of New 

 Jersey. Previously it appears to only have been found on the 

 dorsal fin of the file fish {Alutera schoepHi). 



I have a single example from New Jersey, taken from the dor- 

 sal fin of a rock fish {Roccus lineatus), on September 12th, 1910, 

 by my friend, Dr. R. J. Phillips.
