Holotype. — U.S.N.M. no. 26187: from station 104, latitude i8°3o' 

 40" N., longitude 66°i3'2o"W. to latitude i8°30'io" N., longitude 

 66°i3'5o" W., 80 to 120 fathoms. 



This species somewhat resembles Gaudryina ( Siphogaudryina) si-, 

 phonifera (H. B. Brady), which is characteristic of the Indo-Pacific. 

 In the Atlantic species, however, the test is smaller, more complex, 

 and the tubular projections more numerous but less elongate.

Genotype. — ■Bigenerina robusfa H. B. Brady. 



Test elongate, subcylindrical, the early portion tapering, later por- 

 tion with the sides nearly parallel, rounded in transverse section, 

 earliest whorl with four or iive chambers, rapidly reducing to three, 

 and then to a biserial stage which continues for a considerable period, 

 followed in the adult by uniserial chambers, interior undivided ; wall 

 arenaceous ; aperture in the biserial portion at the inner margin of the 

 last-formed chamber, in the uniserial portion becoming terminal, cen- 

 tral, and gradually increasing from one opening in the early stage to 

 many in the adult, occupying the central portion of the terminal face. 

 Miocene to Recent. 



This genus apparently is derived from Gocsella by the addition of 

 the apertural characters, having a cribrate terminal face with the aper- 

 tures represented by numerous, small, rounded openings in the middle 

 portion. 



Apparently this genus developed in the West Indian region directly 

 from Goesclla in the Miocene, as it is found in the Miocene of Trini- 

 dad, and continues in the same general region to the present oceans, 

 the type species having been described from Challenger material from 

 off the West Indies.

Textularia agglutinans (part) H. B. Brady (not d'Orbigny), Rep. Voy. 

 Challenger, vol. 9, pi. 43, fig. 12 (not figs. 1-3), 1884. 



Test large, much elongate, gradually tapering from the subacute 

 initial end, greatest breadth toward the apertural end, early stages with 

 as many as five chambers, reducing to three, and soon becoming 

 biserial, the megalospheric form becoming uniserial in the adult : cham-
