Uvigerina aculeata, d'Orbigiiy. 

 Obtained at Stations 342 and 459 (not abundant). 



Uvigerina pygmsea, d'Orbiguy. 



This is the most common species of the genus ; it has been collected in all seas, 

 and at all depths from 2 to 2600 fathoms. I have obtained it in fair numbers from 

 Stations 451 (1741 fathoms) and 346 (56 fathoms). 



Uvigerina asperula, Czjzek. 



A few specimens of this species were taken at Station 459, 1998 fathoms. 

 U. asperula is a comparatively common species, and has been found from as far north 

 as lat. 56 and as far south as lat. 52. It was obtained by the Challenger Expedition 

 in the Antarctic at 2600 fathoms. 



Uvigerina angulosa, Williamson. 



This characteristic form was obtained in fair abundance at Station 346, 56 fathoms. 

 It is a widely distributed form, and has been found as far north as lat. 70, and as 

 far south as the Antarctic Continent, in depths ranging from 8 to 1375 fathoms. 



Family GLOBIGEKINIDyE, Ehrenberg. 



Genus GLOBIGERINA, d'Orbiguy. 



Globigerina dutertrei, d'Orbigny. 



This robust dwarfed variety apparently takes the place of Globigerina bulloides in 

 the Antarctic Seas. I have found this species in smaller or greater numbers in most 

 of the deposits obtained by the Scotia Expedition, at no less than fifteen of the twenty- 

 four stations from which I have samples of the deposits, viz. Stations 286, 300, 313, 

 338, 342, 346, 387, 417, 418, 420, 421, 447, 451, 459, and 467. 



Globigerina packyderma (Ehrenberg). 



Dr H. B. BRADY, in describing this species, states that it has not been taken 

 south of the Faroe Channel. I have examined a great number of specimens from the 

 Faroe Channel, Arctic and Antarctic Seas, and Southern Ocean, and can find no specific 

 characters differentiating those taken by the Scotia from those found in the Faroe 

 Channel and Arctic Sea. I have obtained Globigerina pachyderma more or less 

 abundantly from nine stations, viz. 300, 313, 338, 342, 346, 387, 417, 420, and 451. 



Globigerina bulloides, d'Orbigny. 



Obtained at eight stations, viz. 338, 342, 346, 417, 421, 451, 459, and 467. 

 Globigerina bulloides is the most common species of the genus. It has been taken in
