ROTALIINAE 427 



glassy white, but the colour is probably due to protoplasmic contents, as it is most 

 marked in the final chamber. 



Breadth of specimen, about 3-6 mm. 



A single almost perfect specimen, and a fragment only were found in spite of exhaus- 

 tive search among the trawl refuse from WS 225, at a depth of 162 m., but the species 

 being sessile on zoophytes may be of more frequent occurrence than our single specimen 

 suggests. Pending the arrival of further material, we have placed the form in the genus 

 Carpenteria. It appears to have some affinities with C. monticularis, Carpenter, in the 

 arrangement of its chambers and its tubular aperture, but differs very widely in its delicate 

 shell- wall and in the lobose subdivision of the separate chambers.

Rare, and never very typical ; all the specimens are small. This station is considerably 

 to the south of 46° 40' 00" S which Brady gives as the southern limit of the species 

 as identified by him. But he appears to have regarded Rotalina hirsuta as identical 

 with R. canariensis, and to have adopted the latter name. D'Orbigny 's figures and de- 

 scription indicate some marked differences, especially as regards size, and Cushman 

 appears to be justified in reviving d'Orbigny's earlier name R. hirsuta, which is un- 

 mistakably the type so abundant all over the Atlantic Ocean. There is unfortunately no 

 Type of R. hirsuta to be found in Paris, and the Type tube marked R. canariensis contains 

 only a dead shell, opaque and obscurely marked, which throws no light upon the identity 

 of d'Orbigny's R. canariensis. A single feeble specimen occurs at WS 92, which might be 

 ascribed to P. canariensis, on the strength of the borders to the chambers on the dorsal 

 side. All the other specimens are clearly R. hirsuta, characterized by the four chambers 

 visible on the ventral side.

Five stations: 235; WS 88, 89, 225, 408. 



Usually a few specimens only, the best at WS 88, The Falkland Islands specimens 

 represent a common and widely distributed type, found in Globigerina oozes and
