2 THE VOYAGE OF H.M.S. CHALLENGER. 



The eight genera represented in the collection may be referred to seven different 

 families, viz., Cumidse, Vaunthonipsoniidae, Larnpropidae, Leuconidae, Diastylidee, Cumel- 

 lidas and Campylaspidae, all of which are also represented in the Northern Ocean. Of 

 the fifteen species contained in the collection, one only, Diastylis stygia, has been 

 previously described ; all the others I regard as new, although some of them seem to be 

 very nearly related to earlier known species.
