distal margin of the merus are large; those of the carpus are smaller. 

 There are four rows of spines on the palm— one on each margin 

 and two on the surface behind the gape of the fingers; there are 

 also two spines on the crest of the palm, in a parallel line with the 

 maroinal row; a single spine is placed near the middle of the in- 

 side of the palm; the inside surface is roughened b}^ numerous spiny 

 granules. 



The ambulatory feet are compressed and moderately spinose. The 

 abdomen has a line of spines on the second segment. 



The specimen described is a female measuring 33 mm. from the front 

 to the end of the telson; length of larger cheliped, 39 mm.; length of 

 palm, 7 mm. ; length of fingers, 7 mm.

 and seven small.

One of the largest of the small specimens measures 17 mm. in 

 length. The}^ difi^er from the large one taken for the tA'pe in having 

 but one row of spines on the outside of the palm and several in having 

 the third segment of the abdomen armed with only two spines. The 

 supraocular spines are shorter. 



MUNIDA FLINTT, new species. 



The rostrum usually extends l)eyond the eyes about one-half of its 

 length. The supraocular spines are shorter than the eyes, both the 

 rostrum and the supraoculars are smoother than in 3f. affinis. As in 

 that species the normal number of spines on the gastric area is seven, 

 the middle spine, however, is often wanting, the other spines of the 

 carapace are the same as in affinis. The tranverse lines and the gran- 

 ules are not crowded as in affi7iis, and the cilia do not reach from line 

 to line. 



The armature of the abdomen is the same as in affinis except in the 

 lateral spines, which number two on each side of the central pair on 

 the second segment and but one on the third segment, while the fourth 

 segment has only the central pair and a single posterior spine on the 

 median line. The chelipeds are scabrous and spiny; the merus has 

 about fourteen spines on or near the crest, and here and there a single 

 spine on other parts of the surface. The palm of the hand is densely 

 scabrous, the spinules are few and scattered. The dactyl has a row of 

 widely separated spinules on its margin. The prehensile edges of the 

 fingers are set with hair and armed with well separated teeth; between 

 the teeth the edge is crowded with denticles. 



This species is nmch like affiiii.s and sf!mj)sonl in general appear- 

 ance, but very different from either in detail. Named for Dr. J. M.
