The spines of the merus of the inaxillipods iiro larg'e and situated at 

 the extremes of the segment. 



The chelipeds are short, stout, and prismatic; the spines of the distal 

 portion of the merus are very large, becoming smaller proximally. 



There are four rows of spin(\s on the carpus. The largest occupy 

 the crest, the smallest the row on the outer surface near the lower 

 margin. Medium-sized spines occupy the rows that arm the inner and 

 outer surfaces. The outer margins of thetingei-s are each ai-med with 

 four i-ather large spines. 



The second segmiMit of the abdomen is armed with nine spines, which 

 are short and blunt. 



The length of the carapace from the end of the rostrum is 16 nun. ; 

 length of chelipeds, 26 mm. 



One specimen, female, from Alhatrofts^ station 3708, in 60 to 70 

 fathoms, off Honshu Island, Japan. 

 Type.—Gixt. No. 25472, U.S.N.M. 



This species is an addition to the group of which 



\ Munida onilitaris Henderson is the typical example.

ft^^p^a the carapace and in its shorter and less divergent 



p.*''*':^*.'"-^/.*.-^ supraoculars.

fathoms, which dmer from the specmien taken as the 

 tj^pe in that the chelipeds are elongated, and are without any promi- 

 nent spines, there are numerous small spines on the merus and carpus, 

 a few on the pahn, and one or two on the margins of the tingers. 

 There is a hiatus between the tingers, the prehensile edges of which 

 are set with small teeth even in size and with roun:^ed ends; the hiatus 

 which extends the length of the tingers is tilled with bristles which 

 arise from the lower surface of both tingers. 



MUNIDA MEDIA, new species. 



The carapace is widest in the middle; the sides are arcuate, the 

 anterior portion is armed with six or seven spinuies. 



The transverse stria^ are not crowded; are both granulated and cili- 

 ated; the cilia are iridescent. The postocular or gastric spines are 

 small; a nuu'h smaller paired spine stands at the side in line with them; 

 another paired spine is placed farther down near the hepatic region. 

 The cervical groove is deep; where it meets the side there is a notch; 

 the cilia in ])oth branches are longer than elsewhere. The triangular
