BULLETIN 71, UNITED STATES NATIONAL MUSEUM. 



Distribution. — The species seems to have a wide range both in 

 depth and latitude. Brady records it from Challenger station 253, in 

 3,125 fathoms, in the North Pacific. It is more often found in rather 

 shallow water. Bagg records it from four Albatross stations near the 

 Hawaiian Islands, in from 104-1,342 fathoms. The most typical 

 specimens are from Nero station 2071, in 271 fathoms, off the Hawaiian 

 Islands. 



The various figures of specimens assigned to this species show the 

 great variety of forms which have been grouped under this specific 

 name. 



TEXTULARIA AGGLUTINANS d'Orbigny, var. FISTULA, new variety. 



Description . — In general similar to the typical form, but with lateral 



fistulose projections on the early chambers, 

 these in the later chambers becoming ex- 

 tended into a projecting peripheral border; 

 the early chambers are somewhat com- 

 pressed, the later rotund as in typical T. 

 agglutinans. 



Length 1-2 mm. 



Distribution.— Numerous specimens of 

 this variety were found in material from 

 Albatross station H3007, in 323 fathoms, 

 and Nero station 2071 (type), in 271 

 fathoms, both near the Hawaiian Islands; 

 also from Blake Reef, Vincennes Strait, off 

 southern Japan, in 248 fathoms. (Type, 

 Cat. No. 8330, U.S.N.M.) 



The specimens occur with the typical 

 form, and are apparently a fistulose variety 

 of it. In the form and appearance of the 

 extended rim on the later chamber it is 

 very different from T. sagittula, var. fistulosa H. B. Brady, which it 

 otherwise in some ways resembles. 



TEXTULARIA HORRIDA Egger. 



Textularia horrida Egger, Abh. kon. bay. Akad. Wiss. Miinchen, CI. n, vol. 18, 

 1893, p. 270, pi. 6, figs. 11, 12 [T. horroida on explanation of plate]. 



Description. — Test broad, short, compressed, composed of a few 

 low chambers directed backward, each extending outward into an 

 elongated process ; walls rough, made up of cemented particles of cal- 

 careous sand; aperture a curved slit in an indentation of the inner 

 margin of the chamber. 



Length 0.37-0.80 mm.
