145. Ammochilostoma ringens (Brady). 



Trochammina ringens, Brady, 1879, etc., RRC, 1879, p. 57, pi. v, figs. 12 a, b; 1884, FC, p. 343, 



pi. xl, figs. 17, 18. 



Trochammina ringens, Flint, 1899, RFA, p. 281, pi. xxvii, fig. i. 



AmmoiJiilostoma ringens, Eimer and Fickert, 1899, AVF, p. 692. 



Haplophragmoides ringens, Cushman, 1910, etc., FNP, p. 107, fig. 166; 1918, etc., FAO, 1920, 



p. 49, pi. ix, fig. 2. 



One station: WS 351. 



Only a single specimen, quite typical except as regards the aperture, which is on the 

 inner edge of the final chamber, but not above the edge and separated from the previous 

 convolution. This abnormality gives the shell a pseudo-isomorphism with Pidlenia 

 subcarinata. 



Genus Nouria, Heron-Allen and Earland, 19 14 



146. Nouria harrisii, Heron-Allen and Earland (F 113 a) (Plate HI, figs. 14-16). 

 One station: WS 33. 



Quite a number of excellent specimens were found at this station. They vary greatly 

 in size, ranging between 0-3 and o-8 mm. in length, and are rather less broad than the 

 type. Otherwise they agree very well, though there is a greater tendency to use broken 

 spicules and more cement, and to employ mineral grains for filling in odd crannies, 

 especially at the base of the test. The projecting basal spicules are very pronounced in 

 some of the specimens. 



Sub-family LOFTUSINAE 

 Genus Cyclammina, Brady, 1876 



147. Cyclammina cancellata, Brady (F 114). 



Nine stations: 151 ; WS 63, 334, 336, 351, 418, 426, 429, 521. 



Very rare, but good specimens of both megalospheric and microspheric forms, the 

 best at WS 334 and 336. With the exception of WS 418, where a single microspheric 

 individual was found at a depth of 227 m., all the records are from deep water between 

 1 170 and 3780 m. 



148. Cyclammina orbicularis, Brady. 



Cyclammina orbicularis, Brady, 1879, etc., RRC, 1881, p. 53; 1884, FC, p. 353, pi. xxxvii, figs. 



17-19. 



Cyclammina orbicularis, Cushman, 1910, etc., FNP, 1910, p. 113, fig. 173; 1918, etc., FAO, 



1920, p. 57, pi. xi, figs. 7-9. 

 One station : WS 334. 

 Two rather small specimens from 3705 m. at this station.
