stations off the coasts of Mexico and Central America in 660-1,879 

 fathoms. Flint records it from a single station, Albatross D3080, 

 in 93 fathoms off the coast of Oregon. Bagg records it from two 

 Albatross stations, H4566 in 572 fathoms and H4696 in 367 fathoms, 

 both stations near the Hawaiian Islands. In the present work I have 

 had specimens from Albatross station D3431 off California, D4965, 



D4993, D5068, 77-191 fathoms off the coast 

 of Japan; Nero stations 1308, 1311, in 

 1,040 and 1,503 fathoms near the Bonin 

 Islands. Specimens were also obtained from 

 the stomachs of Holothurians taken at Alba- 

 tross station D3608 in Bering Sea. 



There is a considerable variation in the 

 texture of the wall, some specimens being 

 smooth and of very fine material, resembling 

 certain species of Trochammina, while others 

 are of much coarser material. In general, 

 however, the exterior of the test is smoothly 

 finished. A considerable variety of forms have been assigned to this 

 species by various authors, but I have placed here only those speci- 

 mens which have the somewhat compressed form with the rounded 

 chambers, which are characteristic of d'Orbigny's type figure.

Description. — Test nautiloid, planospiral, laterally compressed, 

 consisting of two or more coils, chambers slightly involute, seven or 

 eight in the last formed coil, usually rather indistinctly marked on 

 the exterior; wall rather coarsely arenaceous, often with sponge 

 spicules cemented into the test, 

 aperture an elongated slit at the 

 base of the apertural face; color 

 usually brownish or gray. 



Diameter 1-1.5 mm. 



Distribution. — There are appar- 

 ently no published records for this 

 species in the North Pacific. In the 

 Albatross and Nero collections the species occurs at several stations. 

 Single specimens were obtained from three Albatross stations off Japan, 

 D4970 in 500 fathoms, D4979 in 943 fathoms, and D5086 in 292 

 fathoms. Single specimens were obtained from two Nero stations, 12 

 off the Hawaiian Islands, 1,924 fathoms, and 172 in 2,086 fathoms near
