FOEAMINi:^RA OF THE ATLANTIC OCEAN. 



41 



Length slightly exceeding 1 mm. 



Distribntion. — Type-specimen (U.S.N.M. Cat. No. 19107) from 

 Albatross station D2355, in 399 fathoms (730 meters), in the Carib- 

 bean, off Yucatan, This variety is somewhat similar to var. lacunata 

 (Burrows and Holland), but differs in the distribution of the pits 

 and in the more elaborate ornamentation. Its very thick walls, large 

 size, together with the peculiar ornamentation, will distinguish it 

 from other varieties of the species. It seems to be limited to the 

 western tropical Atlantic. 



Lagena orhignyana, var. antiUea — material examined. 



LAGENA ORBIGNYANA (Seguenza), var. CARIBAEA, new variety. 



Plate 7, figs. 6-9. 



Lagena orhignyana H. B. Brady (part) (not Seguenza), Rep. Voy. Chal- 

 lenger, Zoology, vol. 9, 1884, pi. 59, fig. 24. 



Description. — Variety differing from the typical in the much 

 larger size, thicker-walled test, and the surface which is granular. 



Length up to 1 mm. 



Distrihution. — Type-specimen (U.S.N.M. Cat. No. 19098) from 

 Albatross station D2144, in 896 fathoms (1,639 meters), in the Carib- 

 bean. It has also occurred at a few other stations in this general 

 region. This is evidently the same as the specimen figured b}'^ Brady, 

 and it would be very interesting to know from what locality his 

 figured specimen came. It is much larger thtin the typical form, and 

 is evidently a tropical variety. 



Lagena orhignyana, var. carihaea — nvatcrial examined.
