THE CRUSTACEA OF NEW JERSEY. 119 



inner. Second maxillipeds swollen, fleshy, terminal joints en- 

 larged as hnge, kidney-shaped adhesion pad, without pinchers, 

 knobs or claws. Swimming-legs biramose, each ramus of first 

 two pairs distinctly two-jointed, of third pair partially, and of 

 fourth pair almost entirely fused into single joint. Exopods 

 each armed with stout spines, of similar number and arrange- 

 ment, one at outer distal corner of proximal joint and four as 

 row across end of distal joint. Endopods partly covered with 

 minute papillae or spines. Outside each exopod in three pos- 

 terior pairs small rounded knob, like rudimentary third ramus, 

 bearing on its summit long flexible spine. Basal, joints of each 

 pair of legs subrectangular, increasing greatly in size backward, 

 and those of fourth pair about eight times larger than first. In 

 first two pairs basal joints attached by anterior margins, in third 

 pair by front interior corners, and in fourth pair by centers of 

 interior margins, rami in each case borne on hind margins. In 

 all exopods basal joint much larger than terminal. In endopods 

 of first and second pairs terminal joint larger, and in third and 

 fourth pairs reduced to mere knob on side of basal joint. Fifth 

 legs formed of long papilla, broadly triangular at base and 

 strongly flattened, attached to ventral surface of genital segment 

 half way between lateral margin and median line, with three 

 slender spines. External egg-sacs slender, of even calibre, and 

 reaching length twice rest of body. Color when fresh in alcohol 

 sandy-gray or whitish, without any pigment spots. In life said 

 to be light yellowish-white. Length of body without egg-strings 

 6 mm., and total length sometimes 18 mm. 



Remarks. — This species is known to me from New Jersey by 

 the variety stiiiipso)ii described by R. Rathbun, and Leidy's 

 record of an example taken from the fin of a shark captured at 

 Beesley's Point. I have every reason to believe that the shark 

 in cjuestion is possibly an example in the collection of the Acad- 

 emy, and which I have identified as Eulamia milbcrti, though 

 Leidy mentions that the host was not determined. Leidv says 

 the cephalothorax is a little smaller than the abdominal segment, 

 and between them are three pairs of dorsal lobes which com- 

 pletely cover the space. The egg-pouches are linear and 0.21^
