SOME NEW DEEP SEA CRUSTACEANS— BENEDICT. 



257 



The rostrum i.s long and slender; the lateral margins are denticulated 

 near the apex; the .supraocular spines are united to the rostrum for 

 one half their length. The peduncles of the eyes are short and the 

 cornea very much dilated. The inferior margin of the merus of the 

 maxillipeds is armed with three spines, two on the proximal half and 

 one on the distal angle. The chelipeds are long, slender, cyrmdrical, 

 and scabrous; the inner margin of the merus is armed with about six 

 large spines; there are three on the upper surface; the carpus has a 

 single large spine at the distal inner angle. This species is easily 

 distinguished from an}' other described species from the West Coast 

 by its slender elongated che- 

 liped in connection with the 

 unarmed abdomen.

MUNIDA DECORA, new species. 



The carapace is crossed by 

 six continuous ciliated and 

 granulose lines; between 

 these lines are numerous 

 other lines of the same char- 

 acter, but broken into small 

 arcs, which are arranged in 

 beautiful patterns. The car- 

 apace is nearly devoid of 

 spines; there are two on the 

 gastric area in the usual 

 place, with several spinules 

 in line between and at the 

 sides; posterior to this row 

 there are no spines on the 

 surface. The marginal spines are small. The supraocular spines 

 diverge and reach nearly to the extremities of the eyes. The rostrum 

 is strong — about twice as strong as the supraoculars — and is serrate 

 near the end, above and below, and on the sides. The peduncles of 

 the eyes are very short and much constricted; the cornea is dilated 

 at the sides. The inferior margin of the merus of the maxillipeds is 

 armed with two large and widely separated spines, between which 

 are one or more spinules. 



The chelipeds are broad, flattened, and hairy. The spines of the
