sub-globular, to long and comparatively narrow individuals. It is probable that the 

 extremes represent the micro- and megalospheric forms, and that the species is poly- 

 morphic. It may be noted that Brady's fig. i on pi. Ivi, from a specimen from the 

 Azores, certainly does not represent d'Orbigny's species. The d'Orbigny Types in Paris 

 represent the long, adult form, the early stages not being represented. 



165. Ehrenbergina hystrix var. glabra, Heron- Allen and Earland. 



Ehrenbergina serrata, Chapman, 1914, FORS, p. 31, pi. ii, fig. 16 (only). 



Ehrenbergina hystrix var. glabra, Heron-Allen and Earland, 1922, TN, p. 140, pi. v, figs. 1-6, 



II. 



Ehrenbergina hystrix var. glabra, Cushman, 1927, E, p. 4, pi. i, figs. 7, 8. 



Two stations: 236; WS 79. 



At these stations a few individuals with feebly spinous marginal edges were found, 

 which we think should be attributed to the above. There is no doubt that they are 

 merely spinous variations of the dominant local species E.piipa, and it would now seem 

 probable to us that our variety is nearly related to that species and would have been 

 more correctly placed as var. spinosa of E. pupa, than as var. glabra of E. hystrix. 



166. Ehrenbergina bradyi, Cushman. 



Ehretibcrgifia scrraia, Brady (pars), 1884, EC, pi. Iv, figs. 2, 3, 5 (?) not 4, 6, 7. 

 Ehretibergina bradyi, Cushman, 1918, etc., EAO, 1922, p. 134, pi. xxvi, fig. 5. 

 Ehrenbergina bradyi, Cushman, 1927, E, p. 5, pi. ii, fig. i. 



One station: WS 88. 



A single good specimen. 



Family CHILOSTOMELLIDAE 

 Genus Chilostomella, Reuss, 1850 



167. Chilostomella oolina, Schwager (Plate IX, figs. 38, 39). 



Chilostomella oolina, Schwager, 1878, TDS, p. 528, pi. i, fig. 16. 

 Chilostoynella ovoidea, Brady, 1884, EC, p. 436, pi. Iv, figs. 14, 17, 18. 

 Chilostomella oolina, Cushman, 1925, LER, i, p. 74, pi. xi, figs. 3-10. 



Eour stations: 228, 230; WS 83, 408. 



Two specimens at 230 and a single one at the remaining stations. It is rather curious 

 that these four stations lie in the same area, and almost in a continuous line between the 

 end of Staten Island and the southern extremity of the Falklands. 



Genus Seabrookia, Brady 1890 



168. Seabrookia earlandi, Wright (Plate X, figs. 1-3). 



Seabrookia earlandi, Wright, 1891, SWI, p. 477, pi. xx, figs. 6, 7. 



Seabrookia earlandi, Heron-Allen and Earland, 1913, CI, p. 72, pi. v, figs. 10-12. 



One station: WS 83. 



Two specimens. This little species has a curiously wide distribution. It is probably 



often overlooked owing to its small size.
