IL Order EUPHAUSIAGEA. 



Ail gênera hitherto established, excepting Rhoda (Boreo- 

 phausia), are représentée! in the collection. In order to facilitate 

 comparison the gênera are dealt with in the same consécutive 

 order as in the principal work on the order, viz. the Challenger- 

 Report by Prof. G. O. Sars. 



Genus EUPHAUSIA," Dana 



Of this rich genus only three species have been captured ; in 

 ail probability the majority of its forms live generally or at least 

 frequently not far from the surface.

Remarks. — That this species not mentioned in the Chal- 

 lenger-Report has been secured in 1904 on 12 out of 17 stations 

 proves that it must be extremely common in that part of the 

 Atlantic Océan.
