Lagena orbignyann (?) Sidebottom, Journ. Quekett Micr. Club, vol. 11, 

 1912, p. 418, pi. 21, fig. 15. 



Description. — " Test pyriform or flask-shaped, broad at the base, 

 compressed; ento- or ectosolenian ; furnished with a deep vertical 

 •wing, encircling the oval base; the wing traversed by parallel tiibuli, 

 and sometimes fringed at the free margin." 



Length, 0.42 mm. 



Distribution. — There are numerous records for this species from 

 about the British Isles and elsewhere, but I have seen no specimens 

 referable to it from the western Atlantic Albatross collections. 



LAGENA FLINTIANA, new species.

Lagena orhrgnyana Flint (not Seguenza), Rep. U. S. Nat. Mus., 1897 

 (1899), p. 308, pi. 54, fig. 4. 



Description. — Test somewhat compressed, longer than broad, the 

 basal end broadly rounded, the apertural end much drawn out, body 

 of the test rounded, completely encircled with a thin single keel, 

 inside of which is a slight thickening of the test, but which does not 

 stand up into a prominent ridge of any extent; wall translucent ex- 

 cept for the peculiar thickenings which occur about the border of 

 the body of the test, and especially across the base where the entire 

 wall becomes clouded, as a result apparently of numerous small 

 thickenings which are abundant in that particular portion ; aperture 

 tubular, entosolenian, but with an elongate tube in the body cavity. 



Length up to 0.75 mm. 



Distribution.— ly^Q-s^^oim^n (U.S.N.M. Cat. No. 19064) from 

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

 bean. Flint records this species as Lagena orbignyana Seguenza, but 

 a study of the material from his station shows that he had a very 

 different species. His stations are in the northern part of the Gulf 

 of Mexico, in the Caribbean, between Cuba and Yucatan, off Panama, 

 and west of the Windward Islands. I have had numerous specimens 

 from these same regions. While it is impossible to say without con- 

 sulting Brady's original material, it seems probable that the speci- 

 mens he records as Lagena orbignyana from off the Virgin Islands 

 and off the coast of Brazil are the same species.
