Euchirella rostrata, Claus.

Two specimens were found at 560 and 1370 fathoms 
respectively. 
Euchirella curticauda, Giesbrecht.

Comparatively common throughout the collection, occur- 
ring at nine stations at varymg depths from 810 to 1710 
fathoms. 
The crested head without rostrum, coupled with the 
dwarfed abdomen and caudal segments, easily distinguish 
this species.

1833. Cyclops marinus, Prestandrea, Effemeridi scientifiche e Jetterarie 
per la Sicilia, Palermo, vol. vi. p. 12.

ranean and the Atlantic and Pacific Oceans, and occurring 
in the present collection at eighteen stations and at varying 
depths from 270 to 1770 fathoms. 
Eucheta acuta, Giesbrecht. 
1892. Eucheta acuta, Giesbrecht, F. Fl, Neapel, vol. xix. p. 246.

Mediterranean. 
Eucheta Hessei, Brady. 
1883. Eucheta Hesset, Brady, Rep. Voy. ‘ Challenger,’ vol. viii. p. 63. 
One specimen only apparently of this species was taken at 
1370 fathoms. It had the strong prominent rostrum as 
described and figured by Brady, but being an immature 
specimen, a male, the fifth feet were not so complete as those 
he figures.
