the Azores, and the West Indies (Brady) . Heron- Allen and Earland 

 record the species from two stations in the Clare Island region, off 

 South Cornwall and at 11 stations off the west of Scotland. They 

 note that it is most common in moderately deep water, and in their 

 experience that it is rare in shallow dredgings off the British coast. 

 I have had it at but two Albatross stations, one off the northeastern 

 coast of the United States, and the other south of Cuba.

Description. — Test tetrahedral, triserial, flattened on three sides, 

 apical end bluntly rounded, apertural end broadly rounded; cham- 

 bers distinct, somewhat inflated, generally triangular, the ventral 

 border broadly rounded; sutures distinct, somewhat depressed, wall 

 coarsely arenaceous, somewhat roughened; aperture in a depressed 

 area on the ventral side of the last-formed chamber with a large 

 broad overhanging tooth; color white. 



Length 1.0-1.5 mm. 



Distribution. — D'Orbigny originally described this species from 

 shore sands of Cuba. His name was not even used by Brady as a 

 synonjrm in the Challenger Report, and the species has been entirely 

 neglected since its first description, except that I have shown in a 

 recent paper that it should be used for this common West Indies 

 species of shallow water. I have had specimens from stations on 

 the north coast of Jamaica at Montego Bay, and at Runaway Bay. 

 As Vemeuilina affixa I have recorded it from numerous stations off 

 the coast of Florida and the Bahamas. In the Albatross material 

 it has occurred in the Bahamas, off Yucatan, and at one station in 

 the northern part of the Gulf of Mexico. It is a common and very 

 well characterized species of this region. Its nearest ally seems to 

 be Valvulina davidiana Chapman described by him from Funafuti.
