FORAMINIFERA OF THE ATLANTIC OCEAN, 



43 



Distrihufion. — Wright described this variet}- from off the south- 

 west of Irehind in 750 fathoms (1,370 meters). I have a specimen 

 from Albatross station D2097, off the northeastern coast of the 

 United States, which is simihir to that described by Wright, but it 

 is evidentl}^ very rare, as it has not occurred at any of the other 

 Albatross stations, so far as I have seen. 



Lagcna or'bignyana, var. variabilis — material examined. 



LAGENA ORBIGNYANA (Seguenza), var. WALLERIANA Wright. 



Lagena orbignyana (Seguenza), var. walleriana Wright, Proc. Roy. Irish 

 Acad., ser. 3, vol. 1, 1891, p. 481, pi. 20, figs. 8, 8?^.— Heron-Aixen and 

 Earland, Trans. Linn. Soc. London, ser. 2, vol. 11, 1916, p. 253. 



Description. — Variety differing from the typical in having the 

 center of the convex face ornamented with a rounded boss-like pro- 

 tuberance. 



Distribution. — This was described by Wright from specimens from 

 off the southwest of Ireland in 53 and 145 fathoms (97 and 265 

 meters) . Heron-Allen and Earland record a single typical specimen 

 from the west of Scotland, and there are a few records for it outside 

 the Atlantic. I have failed to find any specimens in the western 

 Atlantic referable to this variety. 



LAGENA ORBIGNYANA (Seguenza), variety. 



Plate 8, fig. 3. 



There are a very few specimens, similar to that figured, which 

 seem to belong to L. orbignyana., but which need further specimens to 

 give them specific character.
