mthitat. Station 23 (Lat. 4° 26' 7" S., long. 10° 1' 8" E.), in a gathering from 85 fathoms. 

 Collected about midday, Eebruaiy 5th. 



One or two specimens only of this species were obtained. The armature of the anterior 

 and posterior foot-jaws, the long and finely serrate terminal spines of the swimming-feet, 

 and the form and armatiu-e of the fifth pair are characters by which this may be dis- 

 tinguished from other allied species.

Euchceta, inarina was one of the commoner species observed in the collection. It 

 occurred in lOG tow-nettings, 47 of which were surface-gatherings and 59 uuder-surface, 

 ranging from 2 to 460 fathoms. 16 of the surface and 41 of the u.nder-surface tow-nettings 

 Avere collected during the day, and 31 of the surface and 18 of the uuder-surface during

A greater number of Euchceta marina carried ova than any other species of
