 appendages is spinose. The general color in life is red. In the alcoholic 

 specimens the color is retained in the chelae and particularly in the .strum.

In M. iris A. M. Edw., the setse are iridescent, as in this species, but the 

 rostrum lacks the lateral spines and the supra-ocular spines are much longer, 

 reaching beyond the eyes ; from M. irrasa A. M. Edw., our species differs in 

 the shape of the hand, in the relatively shorter median rostral spine provided 

 with lateral spines, etc. 



Munida propinqua, sp. nov. 



The carapace of this species is rather fiat ; the rostral spines are scabrous, 

 the lateral reaching to a point beyond the eyes ; there is a prominent spine on 

 the gastric area behind each lateral rostral spine, another on each side behind 

 and external to these, and a pair of very small ones on the median line at the 

 base of the rostrum; besides these there are about four small spines on the 

 anterior half of the carapace. The anterior lateral angle of the carapace is 

 truncated, the lateral border seven-spined. The pleuree of the abdomen are 

 rounded, short, and broad ; the second abdominal segment is furnished with a 

 transverse row of about eight spines, the rest of the segments being destitute of 

 spines ; the terga of the second to the fourth segments are very smooth behind 

 the central transverse fossse. The first joint of the antenna is armed with a 

 long spine, the second joint with one on each side. There is a minute spine at 

 the anteroinferior angle of the carapace. The chelipeds are robust, setose, 

 and spiny ; merus spiny on upper and inner parts ; carpus spiny on all sides ; 

 The hand is furnished with two rows of spines on the lower side, another along 

 the middle of the outer face, and three irregular series along the upper side ; 

 both the fingers are spinulose. Ambulatory limbs setose, spinose along the 

 superior and inferior edges. In small specimens the lateral spines of the 

 rostrum may be shorter than the eyestalks. 



Length, 84 mm.; carapace (including the rostrum), 45.5 mm. ; breadth, 

 26 mm. ; length of cheliped, 96 mm.

This species resembles M. miles A. M. Edw., bvit the carapace of M. pro- 

 pinqua is flatter, the cardiac area is more distinctly circumscribed by a furrow,
