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 antennal acicle extends to 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 acicle 

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

 antennal peduncle is bispinose in some specimens 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. Tiie carpus, propodus, and dactylus 

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

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

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

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

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

 three or four more prominent than tlie 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 some 

 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 166, 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." 



The following are the measurements of an adult male :^ 

 Length of body ... ... ... ... 35 mra. 



„ „ carapace ... ... ... ... 17 „ 



„ „ eye-stalk ... ... ... ... 5*5 „ 



,, „ chelipede ... ... ... ... 25 „ 



„ „ first leg ... ... ... ... 40 „ 



„ „ second leg ... ... ... ... 38 „ 



„ „ dactylus of second leg ... ... ... 12'5 „ 



„ „ propodus of same ... ... ... 7*5 „ 



Some of the specimens are infested by two different Bopyrid 

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

 abdomen — but occurring in different hosts.
