Teztularia conica Goes (not d'Orbigny), Bull. Mus. Comp. Zool., vol. 29, 1896, 

 p. 43. 



Description. — Test tapering, about twice as long as broad, very 

 slightly compressed, broadest near the apertural end, the apical end 

 bluntly pointed, later portion of the test often with nearly straight 

 sides; chambers distinct, numerous, labyrinthic; sutures very clearly 

 marked, not depressed, wall finely arenaceous with an abundance of 

 cement, very smoothly finished; aperture a narrow slit at the base 

 of the inner margin of the last-formed chamber, the sides of the 

 chamber slightly projecting beyond it on each side, sometimes sub- 

 divided into one or more openings. 



Length up to 4.5 mm. 



Distrihution.—Br&dj gives the following Atlantic records: OfiF 

 Bermuda, 435 fathoms (796 meters) ; off Culebra Island, West Indies, 

 390 fathoms (713 meters); off Jamaica, 100 to 250 fathoms (183 to 

 457 meters), and southeast of Pernambuco, Brazil, 350 fathoms (640 

 meters). Flint's specimens were from off Little Bahama Bank, 

 Albatross station D2655, in 338 fathoms (619 meters). I have found 

 the species to be very abundant at numerous stations in less than 

 100 fathoms (183 meters) off the southern coast of Florida, and it 

 has also occurred in the Gulf of Mexico and off the southeastern 

 coast of the United States. This is a very striking species in its 

 labyrinthic chambers and the neatly finished exterior with its clear- 

 cut finely drawn sutural lines. Some of the specimens off Key West 

 in 78 fathoms (143 meters), and off the Barbados in 100 fathoms 

 (183 meters), are very large and broad. They represent the micro- 

 spheric form of the species. Elsewhere the length is usually not 

 over 2-3 mm. 



An examination of the Goes collection shov/s this species under 

 the name of T. conica.
