 limbs are hairy and minutely granulated. The abdominal 

 carinse are more strongly marked than in G. Icevigata.

 11 millim.

Galacantha bellis, n. sp. 



Allied to G. rosfrafa, A. M.-E. * ; the granulations of 

 that species are, however, superseded by small spiniform 

 tubercles ; the central gastric spine is broader and flatter, 

 the lateral spines are narrower and separated by a wider 

 interval, while the spines on the under surface of the base of 

 the rostrum are smaller, and the latter is more elevated. 



Length of body (of a $ with ova) 65 millim. ; length of 

 chelipedes 38 millim.

Ptychogaster Milne-Edwardsi, n. sp. f 



Rostrum more than twice the length of the ocular peduncles, 

 spiniform and upturned. Carapace covered with spines 

 arranged in longitudinal rows. Chelipedes and ambulatory 

 limbs very long and slender, covered with rows of spines j 

 the digits of the chelse smooth and their apposed edges fur- 

 nished with short hairs and a few minute teeth. All the 

 abdominal segments thickly beset with small spines. 



Length of body (of a ^) 55 millim. ; length of chelipedes 

 118 millim. 



Loc. Station 310 [Straits of Magellan], 400 fathoms. 



Ptychogaster Icevis^ n. sp.
