Specimens of this species have been noted in material from the 

 following Albatross stations in the area: D5201, Sogod Bay, southern 

 Leyte, 554 fathoms (1,012 meters), bottom temperature 52.8° F. 

 (11.5° C); D5242, in 191 fathoms (350 meters), off Pujada Bay, 

 bottom temperature 64.1° F. (17.8° C); D5300, China Sea, off south- 

 ern Luzon, 265 fathoms (485 meters); D5301, in 208 fathoms (381 

 meters), China Sea off Hongkong, bottom temperature 50.5° F. 

 (10.2° C); D5420, in 127 fathoms (233 meters), between Cebu and 

 Bohol, bottom temperature 59° F. (15° C); D5445, east coast of 

 Luzon, 383 fathoms (699 meters), bottom temperature 44.3° F. (6.8° 

 C); D5601 in 765 fathoms (1,399 meters), also in the Gulf of Tomini, 

 Celebes; and D5613 in 752 fathoms (1,375 meters) also in the Gulf of 

 Tomini. 



This is a rather distinctive species, easily distinguished by its 

 few chambers in each volution and the peculiar fimbriate appearance 

 of the area about the aperture, especially in well-developed speci- 

 mens.
