antiM-oliilcral spino. The posterior spine is situated just l)ehind the 

 l)ran(h of the eervieal suture, as indicated b\' a slight notch; the aute- 

 rioi- bi-anch of the suture ends in a notch just behind the anterohit- 



eral spine; both branches are 

 indistinct, while the groove is 

 well marked liehind the gastric 

 area. 



The carapace is roug-hened 

 l)y short, granulose rugje; 

 there are no spines on any part 

 of the gastric area. The spines 

 of the ambulatory legs are con- 

 fined to the crests of mei'us and 

 carpus. The chelipeds have 

 spines on the crest and on the 

 inner margin of the merus and 

 on the distal margin of the 

 carpus. 



The lower margin of the hand 

 is nearly straight, with a slight 

 swelling at the palm and a slight 

 sinus at the base of the fingers; 

 the fingers are acuminate, the 

 outline of the closed fingers 

 from the Imse to the tip is tri- 

 angular. This feature distin- 

 guishes the species from all related forms of the subgenus Galathodes. 

 The two specimens, one male and one female, were taken l)v the 

 Albatross at station 2663, in 421 fathoms, ofi' South Carolina.

MUNIDOPSIS BAHAMENSIS, new species. 



The rostrum is seven-eighths as long as it is broad at the base, 

 measured from the base to the base of the lateral points; between the 

 points it is three-fourths the length of the base. The lateral teeth are 

 large and stand out well from the margin. The inferior margin of 

 the merus of the maxillipeds is armed with three spines; the proximal 

 spine is broad at the base; the second is as long and is uniform in 

 size; the third is short, sometimes inconspicuous or wanting. The 

 merus of the chelipeds has two rows of spines and two large spines 

 between them; the carpus has a large spine at the inner angle and a 

 smaller one at the condyle; the palm is broad and unarmed; in large 

 specimens there is a hiatus between the fingers. The upper margins 

 of the meral joints of the ambulatory feet bear a row of spines; the
