COPEPODA 121 



features different from those of the adults; the Re III has no secretory pore at the base of Se I; the 

 outer tooth of Ri I pes II is bhuit, and the corresponding accessory tooth of pes III is just indicated 

 (text-fig. 30 c). The inner margin of the second basipodite is smooth in the male, but has in the female 

 about 10 short delicate but rather stiff bristles. The pes V is similar to that of E. rostrata, but there 

 is no indication of subdivision of Re; the terminal spine of Re dext. is longer and less sharply set 

 off, and that of left Re is much shorter (text-fig. 30 e). 



Variation. In a single male the exopodite of the second foot was curiously transformed, as seen 

 in fig. 2 b (PI. VIII). 



Occurrence. The Ingolf Expedition has not taken any specimen of this species, but the Thor 

 has gathered it at the following stations.

Distribution. "This species" is according to Far ran "of frequent occurrence, and often moder- 

 ately common" on the west coast of Ireland "at depths of from 200 to 1000 fathoms". It has been taken 

 by the Monaco Exp. and by the Gauss' Exp. as far south as c. 10° Lat. S. It has been recorded from 

 the Bay of California and from the Malay Archipelago. 



Remarks. This species is certainly identical with that described by Giesbrecht and Esterly, 

 though it is somewhat bigger, and in spite of some features, e. g. shape of fifth thoracic tergite, which
