Seven specimens, all females, were found in plankton collected with the Hensen vertical 

 net- at the following stations. 



Stat. 118 (900 metres to surface), 1 specimen. — Stat. 12S (/oometres to surface), 1 specimen. — 

 Stat. 141 (1500 metres to surface), 2 specimens. — ■ Stat. 185 (1536 metres to surface), 1 

 specimen. — Stat. 230 (2000 metres to surface), 1 specimen. — Stat. 276 (750 metres to 

 surface), 1 specimen. 



Euchirella atrlicauda is easily distinguished from the other species of Euchirella, by 

 the high crest on the forehead, by the absence of a rostrum, by the very short abdomen and 

 symmetrical genital segment, and by the row of twelve to thirteen teeth on the inner margin 

 of the first joint of the basiopodite of the fourth pair of feet. 



This species is widely distributed fróm the deep water of the Pacific Ocean to the North 

 Atlantic. I have seen a number of specimens from the deep water of the Faröe Channel, and 

 they do not differ in any way from those collected by the 'Siboga' in the Malay Archipelago. 



4. Eitchirella galeata Giesbrecht.

Euchirella galeata Farran, 1908, p. 37. 



Twenty females and two immature males were found in the plankton collected at the 

 following stations. 



Stat. 71, 3 specimens. — Stat. 118 (HENSEN vertical net 900 metres to surface), 1 specimen. — 

 Stat. 141 (Hensen vertical net 1500 metres to surface), 1 specimen. — Stat. 142, 2 speci- 

 mens. — Stat. 143 (HENSEN vertical net 1000 metres to surface), 1 specimen. — Stat. 14S 

 (HENSEN vertical net 1000 metres to surface), 2 specimens. — Stat. 203 (HENSEN vertical 

 net 1500 metres to surface), 4 specimens. — Stat. 230 (HENSEN vertical net 2000 metres 

 to surface), 4 specimens. — Stat. 243 (HENSEN vertical net 1000 metres to surface), 2 

 specimens. — Stat. 276 (HENSEN vertical net 750 metres to surface), 2 specimens. 



This species can be readily recognised by its high crest, and by the presence of a rostrum. 

 The inner margin of the first joint of the basiopodite of the fourth pair of feet is furnished 

 with one or two moderately long teeth
