This species figured and described by d'Orbigny from off the Cana- 

 ries is recorded by Siddall and by Heron- Allen and Earland from about 

 the British Isles. They do not, however, figure any specimens of the 

 species, and this seems to be the only region from which it has been 

 recorded. It has not occurred in the western Atlantic.

All of the records for this species are from the Pacific. There are, 

 however, single specimens from two Albatross stations D2679, off 

 the Carolina coast, in 782 fathoms (1,430 meters), and another of! 

 Ragged Key, Florida, in 75 fathoms (137 meters), which are smooth 

 at the apertural end and more or less costate at the apical end, in gen- 

 eral resembling this species.

Description.— Test ovate in front view, circular or nearly so in end 

 view, the apex broadly rounded; visible chambers several, little 

 inflated; sutures but slightly compressed; wall smooth; aperture 

 rather narrow with a plate-like tooth; color white. 



Length 0.75-1.20 mm. 



Distribution. — Specimens referred to this species are common, 

 especially along the eastern coast of the United States, as well as 

 in the Gulf of Mexico, and a few in the Caribbean. The specimens 

 either vary considerably, or what is more likely from a study of a 

 considerable series, there are two or more distinct forms in the area. 

 One of these is short and broad, the other longer and more like the 

 original figure given by d'Orbigny for this species.
