This is one of the most characteristic forms in the Kerimba dredgings, occurring at 

 practically every Stn. and often in considerable numbers. The specimens exhibit an 

 enormous range of variation, two types being predominant : (i.) a short broad type in 

 which the gaudryina chambers are numerous, the textularian chambers being limited 

 to one or two pairs ; and (ii.) a long narrow type in which the gaudryine chambers are 

 few in number and are followed by from three to six pairs of chambers on the 

 textularian plan. These long specimens are, as a rule, much more neatly constructed 

 than the short broad individuals, but the texture throughout is of a coarse rough type, 

 similar to the specimens originally figured by Brady {ut supra) under the name 

 G. pupoides. None of the neatly constructed tests subsequently figured under the 

 name "■ scah'a " (B. 1884, FC.) were found ; probably this type of shell is confined to 

 deep water. 



There is very little doubt but that this species is closely allied to Vemeuilina poly- 

 stropha Eeuss ; indeed, it is often difficult to distinguish the short broad specimens 

 from that species, except by the characteristic textularian aperture. It is, perhaps, 

 merely a dimorphous variation of that species.

Not uncommon at Stn. 11, and rare at Stn. 13, but not otherwise recorded. The 

 specimens are all remarkable, owing to the fact that the terminal textularian chambers 

 are practically square in section, the outer edges being parallel instead of curved.
