BULLETIN 104, UNITED STATES NATIONAL MUSEUM. 



Description. — Test close-coiled, somewhat longer than broad, 7 or 

 8 chambei"S in the last-formed coil, periphery slightly keeled or at 

 least acute, apertural face broad and truncate, triangular ; chambers 

 not inflated; sutures curved, very slightly if at all depressed; wall 

 smooth; aperture radiate at the periphery. 



Length, up to 1 mm. 



Distribution. — This species was originally described by D'Orbigny 

 from the Antilles. It is a small, not very conspicuous species. 

 There are numerous records for it in the western Atlantic. Brady 

 records it from the Challenger collections from off Sombrero and 

 Culebra Islands, and off Bermuda, and also off the southeastern 

 coast of South America. Flint recorded it from several stations 

 along the eastern coast of the United States, in the Gulf of Mexico, 

 and in the Caribbean, and Goes also records it from the Gulf of 

 Mexico. I have had numerous specimens which can be referred to 

 this species from the Caribbean and the Gulf of Mexico and the 

 eastern coast of the United States. From the eastern side of the 

 Atlantic it is recorded by Pearcey in the warm area of the Faroe 

 Channel, by Earland from off Bognor, Sussex, and by Heron-Allen 

 and Earland from the Clare Island region and from the west of 

 Scotland. Specimens on the coast of England, however, are recorded 

 as very rare. Most of the other records for the species are from 

 moderate depths in the Indo-Pacific. The specimens that I have 

 figured as this species from the Philippines do not belong here.

 There are a few Challenger stations in the Atlantic from which 

 this species is recorded, one in the western Atlantic, off Culebra 

 Island, 390 fathoms (713 meters), one off the coast of Brazil, 675 

 fathoms (1,234 meters), and two others in deep water, one just south 

 of the Equator, and the other southeast of the Azores. Pearcey has 

 recorded it from deep water in the South Atlantic. The only Eu-
