MUNIDOPSIS SCABRA. 93 



edges of fingers toothed. Ambulatory limbs setose, hind border of dactyli 

 spinulose. 



Length, 19.5 mm.; carapace, 11.5 mm.; rostrum, 2.6 mm.; breadth of 

 carapace, 7.5 mm. 



Station 3384. 458 fathoms. 1 fern. 



This species, which belongs to the genus Galathodes as recently restricted 

 by MM. A. Milne Edwards and Bouvier, resembles M. trideututu (Esmark), 

 M. Mifrons (A. M. Edw.), and M. tndcns (A. M. Edw.). It differs from all 

 these species by its dense pilosity, the shortness of the rostrum, and the 

 great breadth of the hand at the base of the fingers. It further differs from 

 M. tridenlata through the possession of a pair of gastric spines, and through 

 the absence of prominent spines on the meri of the ambulatory appendages; 

 from M. latifrvns through the presence of gastric spines, and the absence of 

 spines on the tergum of the second abdominal somite ; from M. tridcns 

 through the presence of five internal meral spines and one powerful internal 

 carpal spine borne by the cheliped. M. tridentata comes from the eastern 

 Atlantic, M. Mifrons from the Barbadoes, M. tridcns from St. Kitts.

The rostrum is triangular, slightly curved upward, carinated above, the 

 lateral edges and the carina lightly denticulated. The carapace is covered 

 with squamous setiferous tubercles, which end in spiny points. There is 

 a transverse row of six more prominent spiny tubercles on the gastric region. 

 The posterior border of the carapace is ornamented with a denticulated run 

 (about eight denticles). There is a spine between the eye and the antenna 

 below the anterior margin of the carapace. The abdomen is devoid of 

 spines, the pleursB have truncated lateral angles. A very short spine pro- 

 jects over the cornea of the eye. The antenna} are shorter than the body ; 

 a spine on the outer side of the basal joint, one on each side of the .second 

 joint, and one on each side, and one on superior margin of the tlurd joint. 

 The chelipeds are long, spinose, except the fingers; hand long, the basal 

 part longer than the fingers. All the joints of the ambulatory appendages 

 are spiny, except the dactyli.
