Euphausia diomedese, now spec. 



Frontal part of the carapace produced as a broad triangular-pointed plate, 

 arched over the eyes, and covering their peduncles. Anterior part of carapace 

 with a sharp keel, the lateral margins with two denticles on each side. Seg- 

 ments of the abdomen smooth, without spines. Sixth segment longer than the 

 preceding. Preanal spine tridentate. Eyes of moderate size. Basal joint of 

 antennulse with a projecting leaflet above, divided into two lappets at the top. 

 Outer corner of the antennal scale unarmed. Subapical spines of the telson 

 finely denticulated at inner edge. Inner plate of uropoda a little longer than 

 outer, both shorter than the telson. 



This species agrees with E. pellucida in most respects, but the rostral plate is 

 very different, being in E. pellucida acutely produced and not broadly arched 

 over the peduncles of the eyes. Perhaps E. diomedece might be better re- 

 garded as a variety of E. pellucida. 



Station of the " Albatross " : — 



3409. Surface. (Bindloe I., Galapagos.) Two specimens, associated with 

 E. pellucida.
