ROTALIINAE 42S 



Anomalvia vermiculata bears much more resemblance to A. coroiiata, Parker and 

 Jones, than it does to A. polymorpha, Costa, to which species Brady doubtfully attri- 

 buted his Bermuda specimen. In fact large specimens of A. vermiculata can best be 

 separated from A. coronata by the narrow width of their peripheral edge when looking 

 at the apertural face, compared with the broad edge of ^. coronata. Young individuals, 

 on the contrary, are quite distinctive in appearance as compared with A. coronata, but 

 bear some resemblance to A. grossenigosa, GiJmbel,so far as the dorsal surface is con- 

 cerned, though differing in the ventral aspect. 



It is possible that A. vermiculata has a more southerly distribution than A. coronata. 

 Brady's figure 7 on Plate 97, Anomalina polymorpha (?), was drawn from a specimen 

 dredged off Bermuda at 435 fms. His figured specimens of A. coronata are from 

 Prince Edward's Island and the Canary Islands. The majority of the records of A. 

 coronata are from northern seas, and although Brady gives some southern records for 

 that species, including the Falkland Islands, it is impossible to say, without examination 

 of his specimens, to what extent A. vermiculata figures among them. If, as seems pos- 

 sible, the specimens figured by Cushman and Wickenden (C. & W. 1929, FJF, p. 14, 

 pi. vi, figs. 6 a, b, c) from Juan Fernandez Island under the name " Anot?ialina {}) 

 species" are A. vermiculata, the range of the species extends into the Pacific also. 



At WS 246, close to the Falkland Islands, but outside the Continental Shelf, a very 

 interesting specimen was found, in which the final chamber terminated in a cyst formed 

 of very fine mud, which cyst was tightly packed with a young brood of individuals, each 

 apparently consisting of a proloculum and one or two subsequent chambers (fig. 15). It 

 is presumably a case of the formation of a young brood by the Anomalina, but, in the 

 present state of our knowledge, one cannot be certain that the cyst and its contents do 

 not represent a separate organism, which had become attached to the Anomalina.

Three stations: WS 88, 90, 93. 



Represented by single typical specimens only at each station. The original figure of 

 Parker and Jones represents a form in which, even at its narrowest point, the peripheral 

 edge is flat and broad throughout, and coarsely perforated. The two surfaces of the shell 

 are comparatively devoid of perforations. Since the original publication, figures of the 

 species have often shown a narrowing of the edge of the earlier chambers of the last 

 convolution. This may be due to confusion of a northern species A. coronata with the 

 distinctive southern form described under the name of ^. vermiculata.
