This species resembles M. valkla Smith and M. miles A. M. Edw., but the 

 carapace of 31. propinqita is flatter, the cardiac area is more distinctly circum-

 and the abdominal segments are not so much sculptured.

Carapace rather flat and quadrangular. Supraocular spines less than 

 one half the length of the rostrum, shorter than the ocular peduncle. 

 Four spinules on the gastric area arranged in the form of a square, — two 

 behind each supraocular spine ; a longitudinal row of obsolescent spinules 

 in the median line from base of rostrum to the cardiac area; one spine 

 on the cardiac region, a pair on the intestinal region, and one on each side of 

 the cardiac region just back of the cervical suture. The lateral margins of 

 the carapace are armed with about seven spines, the first of which is the 

 largest. The second abdominal segment is armed with a transverse row of 

 six spines, the third with a row of four, the fourth with a row of four, and 

 one median spine behind the transverse row. This is the normal arrange- 

 ment, but in one specimen out of the four there is an additional pair of 

 spines on the second and third segments back of the transverse row. The 

 pleurfB of the third, fourth, and fifth abdominal segments are acute. Eyes 

 very large, reniform. The chelipeds are very long and slender, the merus 

 spinose (the chief of the spines being on the inner side of the joint), the 

 carpus also is spinose. The hand has about eight spines on the upper mar- 

 gin and one on the lower; there are several acute spines on the outer border 

 of the movable finger, the cutting edges of the fingers are straight, finely 

 denticulated or spinulose.
