BIOLOGICAL SURVEY OF 



Order CUMACEA 



In view of the uncertainty as to the division of this order 

 into families, I give below a revision of Stebbing's (1913) 

 scheme. It is based primarily on the presence or absence of 

 the telson, the number of pleopods in the male, and the number 

 of pereiopods furnished with exopods. 



Ceratocumatidae 

 Hemilampropidae 



Diastylidae 



Pseudocumatidae 



Lampropidae 



Dicidae 



Vaunthompsoniidae

 Nannastacidae

To determine our species one must refer especially to Cai- 

 man (1912) and Stebbing (1913) for literature, and to Sars 

 (1871,1900) for figures.
