Note. — In 1839 d'Orbigny figured this species as a somewhat high, inflated, 

 rotaliforni type, having a single small-looped aperture visible only on the under- 

 side, and confined to the last chamber. His specimen was evidentlv drawm from 

 a thin-walled surface-, or shallow- water, specimen. It represents a very dis- 

 tinctive type, dift'ering considerably from G. bulloides (which it closely resembles 

 as seen from the superior side), in having this single aperture to the final chamber, 

 instead of each chamber opening, as in G. hdlloides, into the umbilical recess. 

 After the Cuba monograph the species seems to have been entirely ignored, and 

 although it occurs commonly in company with G. bulloides, and much wor]<: 

 was done with the Globigerina oozes, it was not separated again until Brady dealt 

 with the " Challenger " Collections, when he re-figured the species, using a thick- 

 walled benthic specimen as his type, his figure thus dift'ering slightly from 

 d'Orbigny's. But he fully recognized the distinctness and importance of the type, 

 though curiously enough it is not represented in his table of Clobigerinae found 

 in the various types of deep-sea deposits, including Globigerina ooze, although 

 it does figure in his table of characteristic Foraminifera from high latitiules north 

 and south. Even there it figures from one Station only in the Antarctic, and 

 from none of the Arctic gatherings. It is probable that these records of material 

 were not worked out by Brady himself, but by assistants, who failed to dis- 

 tinguish the type, with the result that Brady in his Report (p. 601), conunits 

 himself to a statement that " G. dutertrei takes the place of the typical G. 

 bulloides in the Antarctic Seas, just as G. jKichyderma represents the type in 

 Arctic latitudes." 



This is not the case ; our own examination of material from the northern 

 North Sea had long ago proved to us • that G. dutertrei gradually replaces G. bul- 

 loides as we go north, and now our work on the " Terra Nova '' material proves
