Seven specimens, all females, were found in plankton collected with the HENsEN vertical 
net at the following stations. 
Stat. 118 (900 metres to surface), I specimen. — Stat. 128 (700 metres to surface), I specimen. — 
Stat. 141 (1500 metres to surface), 2 specimens. — Stat. 185 (1536 metres to surface), I 
specimen. — Stat. 230 (2000 metres to surface), 1 specimen. — Stat. 276 (750 metres to 
surface), I specimen. 
Euchirella curticauda is easily distinguished from the other species of Euchzrela, 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 from the deep water of the Pacific Ocean to the North 
Atlantic. I have seen a number of specimens from the deep water of the Faroée Channel, and 
they do not differ in any way from those collected by the ‘Siboga’ in the Malay Archipelago.

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), I 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. 148 
(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
