bears numerous hairs, which become more evident as the acute apex is approached." 

 In the present species it will be seen that this appendix is not nearly a third longer 

 than the ramus, and that its terminal part is free from hairs. 



In all the above remarks the comparison is instituted between male specimens. 



Length of specimen figured 1 1 mm. C. pilosa described by Milne-Edwards was about 

 6 lines long, C. aculeata, Haswell, 9/l6ths of an inch, C longistylis, Miers, 9 mm. 



Localities. Taken by Mr Crossland at Zanzibar in 1901 and at Wasin in 1902.

This genus and this species have been so fully discussed recently by H. J. Hansen 

 and contemporaneously by myself that I refrain from adding further comment, except 

 to note that in minute points of detail specimens show some variation, which may or 

 may not be due to the age or local circumstances or personality of the individual. 



Locality. At Wasin Mr Crossland in 1902 obtained specimens of both sexes from 

 a depth of 10 fathoms and between 6 and 9 fathoms, and one male between 7 and 

 10 fathoms. 



PARAGILICMA, n. gen. 



This genus belongs by its pleopods to Hansen's Spha^rominse hemibranchiatae, 

 even the narrowly triangular endopod of the first pleopods by their breadth at the base 

 conforming to his measurement, "Endopod of pip. 1 at least rather broad, scarcely ever 

 half again as long as broad." It agrees also with his section Cymodicini, but cannot be 

 assigned to any of the genera (or in his view sub-genera) which he distinguishes in that 

 section. The uropods in agreement with Ciliccea exclude it from Cymodoce. The want 

 of any medio-dorsal process on the anterior part of the pleon excludes it from Ciliccea. 

 The presence of a median lobe in the terminal notch of the pleon excludes it from
