Family TEXTULARIID^E. 



Sub-family SPIROPLEOTIN^E. 

 Genus SPIROPLECTA. 



Spiroplecta americana, Ehrenberg. 



Obtained (rare) at one station by the Scotia, 459, 1995 fathoms; the only other 

 record for this species, so far as I am aware, is by the Challenger Expedition, off Raine 

 Island, North Australia, 155 fathoms. 



Spiroplecta biformis, Parker and Jones. 



This minute species in its typical form was obtained (rare) at Station 337a, 2110 

 fathoms. S. biformis is readily distinguished from its allies by the uniform manner in 

 which its test is built, consisting of very fine arenaceous material and brown cement. 

 It is to be found more frequently in the Arctic Seas, as far north as 80 lat., in depths 

 varying from 27 to 145 fathoms; in the South Atlantic east of Buenos Aires, 1900 

 fathoms ; and in the South Pacific, 2375 fathoms. 



Sub-family TEXTULARIIN.E. 



Genus TEXTULARIA, Defrance. 

 Textularia conica, d'Orbigny. 



Obtained at Station 342 (rare). T. conica is a very generally diffused species, 

 and is found most abundantly in the coral seas of the tropical and subtropical regions. 



Textularia concava (Karrer). 



This species was taken (rare) at Station 342, 1946 fathoms. It is recorded from 

 several stations in the North Atlantic, from 173 to 2750 fathoms; from the South 

 Atlantic, in mid-ocean, 2475 fathoms ; and at a number of stations in the Pacific Ocean, 

 from shallow water to 2600 fathoms. 



Textularia agglutinans, d'Orbigny. 



Found in the material from Station 459, 1998 fathoms. T. agglutinans is perhaps 

 the commonest species of the genus Textularia, and the most typical arenaceous variety ; 

 it has a cosmopolitan distribution, both geographical and bathymetrical, and has been 

 recorded in depths ranging from 5 to 3125 fathoms. 



Textularia aspera, H. B. Brady. 



Obtained (rare) from one station only, 467. 2645 fathoms. This species has a geo- 

 graphical range from the Faroe Channel to the North Pacific, and has been collected in 

 depths from 210 to 2900 fathoms.
