sutures distinct, depressed only in the last two or three chambers of 

 the adult; wall ornamented by numerous fine distinct longitudinal 

 costae, running the entire length of the test, usually somewhat 

 oblique; aperture at the dorsal side, somewhat projecting, radiate. 



Length of adult specimen up to 2 mm. 



Dwtribution. — Type-specimen (U.S.N.M. Cat. No. 17434) from 

 Albatross station D2641, in 60 fathoms (110 meters), off the coast of 

 southern Florida. It has occurred at a number of stations as indi- 

 cated in the table, from Florida northward along the eastern coast 

 of the United States, some of the stations in comparatively shallow 

 water. 



This species in some ways resembles the three preceding. It does 

 not have the spinose initial end nor the ornamentation of typical 

 VaginuUna linearis^ and is much smaller and very much more com- 

 pressed than either V. americana or V. hermude7ms. 



VaginuUna advena — material examined.
