The iiiFerior border of the inerus of the inaxillipeds is armed with 

 three or more .spin(\s o»i the ])roxinial and one on the distal (Mid. 



The ehelipeds are shorter than those of J/, /irasa. The nierus has 

 three ro\Ys of ten or more spines in »>()od alignment; the surfaces on 

 each side of the middle row are tlat and diverge at an angle of 90 

 deo-rees. There are seven or eight spines on the carpus and two rows 

 on the inside of the palm; all of the articles are scabrous throughout. 



The abdomen is unarmed. 



The type specimen is an ovigerous female, and is more nearly perfect 

 than the others. Unfortunately, the exact locality is unknown; it is 

 labeled ''Caribbean Sea, 1S84.'' All of the other specimens come from 

 the north of Cul>a. These specimens differ from the type in having 

 the supraocular spines less divergent and in having three spines on 

 the m(n-us of the maxillipeds where the type has four; the distal 

 terminal spine is also wanting in these specimens. The type measures 

 from the front to the end of the telson 82 nmi.; width. 12 mm. ; length 

 of ehelipeds, 38 mm.; length of palm, !> mm.; length of fingers, 1» mm. 



Locality. — Albatross station 2159; 98 fathoms; one male and one 

 female.

MUNIDA SIMPLEX, new species. 



The carapace is l)roadest behind; the transverse ciliated lines are 

 well separated; the cilia are iridescent and extend forward one-fourth 

 of the distance to the next line. There are six spines in line near the 

 front of the gastric area and a single spine at the extremes of the first 

 ciliated line. Two paired spines are situated in the fork of the cervi- 

 cal suture, making twelve spines in all on the surface of the carapace. 



The eyes are large; the supraocular spines extend to the cornea. In 

 the type specimen the lower border of the merus of the maxillipeds is 

 armed with a long spine and three rudimentary ones in the other speci- 

 mens; the merus has but one or two rudimentary ones. 



The ehelipeds are long and cylindrical, and under a lense they are 

 lightly scabrous; the scale-like areas are bordered with iridescent cilia. 



The merus has about twenty-five spines, large and small, in a dorsal 

 view. The spines of the carpus are small; there is a row of small spines 

 near the crest of the palm. The hands are long and a little curved 

 inward, and l)ent slightly downAvard from the base of the fingers, 

 which are a little longer than the palm. In the speciuien selected for 

 the type the ehelipeds are unequal; the left one is the smaller, and 

 has the most marked bend at the base of the fingers, making a large 

 shallow sinus in the lower outline; the outline of the dactyl is eon- 

 cave; the curves in the right hand are not so strong as in the left, and
