This species (which was omitted from the General Catalogue of 

 S.A. Crustacea, Stebbing, 1910) bears a strong likeness to the 

 species of Arcturopsis as regards the relative size of the 4th peraeon 

 segment. The " marsupial pouch of the fourth segment has a row 

 of tubercles below the hinge-line," but the number of pairs of 

 marsupial pouches is not given. 



The pleon, judging from the figure, consists of one segment with 

 lateral indications of another fused with it. 



The male is unknown, unless it is perhaps the following species, 

 which was taken at same place and time. 



Stebbing (I.e.) remarks that this species should probably be 

 referred to Arcturella, but this was before Koehler instituted 

 Arcturopsis. Its true position can therefore only be ascertained 

 by the discovery of the male and the determination of the absence 

 or presence of the $ appendage on the 3rd (or 5th) peraeon 

 segment.

(This species was also omitted from the Catalogue). 



The sex is not stated. If a female it can hardly belong to the 

 genus Arcturopsis, owing to the absence of lateral protuberances on 

 the 4th peraeon segment.
