middle of the last joint of the antennular peduncle. The ophthalmic 



scales are rather small, and separated by a considerable interval, with 

 their apices acute and entire. The antenna! aciclc extends bo about 

 the middle of the terminal joint of the antennal peduncle ; it is straight 

 and acute, with a few short spines on its inner margin, and sometimes 

 also on its outer margin, concealed by the hairs with which the aciclc 

 is clothed. The external prolongation of the second joint of tlvo 

 antennal peduncle is bispinose in some sjoecimens at least ; the third 

 joint is produced inferiorly into a strong spine. The antennal flagel- 

 lum is of moderate length, extending to the tips of the chelipedes, and 

 is fringed with long hairs. 



The chelipedes as well as the ambulatory legs are clothed with 

 long silky hairs. The chelipedes are subequal in most specimens, but 

 in some males the right is larger. The carpus, propodus, and dactylus 

 are armed with short acute spines, some of which are horny tipped, 

 and the majority give rise to bunches of silky hairs. On the upper 

 surface of the carpus there is a median longitudinal smooth area, with 

 rows of spinules on either side. The spines are arranged irregularly 

 on the upper surface of the hand and fingers, but there are always 

 three or four more prominent than the others on the inner margin of 

 the hand. The apices of the fingers are horny. " 



The ambulatory legs ' are long and slender, especially the second 

 pair; all the joints are provided with long marginal hairs. In - 

 specimens a few spinules are met with on the anterior margin of the 

 carpal and propodal joints, and in older specimens they appear to be 

 represented by slight tubercular elevations. The dactyli are about one 

 and a half times the length of the propodi. 



In a note accompanying the specimen from Station 1 66, the colour 

 during life, according to Surgeon- Captain Anderson, was as follows : — 

 " Legs and anterior part of carapace light pink. Eye-stalks rather 

 darker pink,"

Some of the specimens are infested by two different Bopvrid 

 parasites — one living in the branchial cavity, the other attached to the 

 abdomen — but occurring in different hosts.
