Variety, tiareUa Venill. 



A variety occurred in company with the typical form, at station 1020, 

 182 fathoms, in which the subsutural carina is well developed antl 

 crowned by its row of long hairs, but the other carinine are nearly obso- 

 lete, and only bear rows of short, inconspicnous hairs; the epidermis is 

 elsewhere thick and lamellose, not hairy. The spire is a little more ele- 

 vated. 



Off Martha's Vineyard, stations 869, 878, 939, 1025, 1026, 1033, 1038, 

 in 142 to 258 fathoms, 1880 and 1881,— U. S. Fish Commission. A small 

 specimen was taken in 1873, at station 21 b, 52 to 90 fathoms, near 

 Cashe's Ledge, off the coast of Maine, by the party on the Bache. 



Fossarus elegans Venill and Smith. 



Verrill, Trans. Conn. Acad., v, p. 522, pi. 57, fig. 2S, June, 1882. 



Shell small, ovate, with a short, acute, turreted spire, and five angu- 

 lated and sharply carinated whorls, elegantly latticed between the cari- 

 naj. The whorls increase rapidly, the last being relatively large. On 

 the last whorl there is a sharp angular carina at the shoulder, often with 

 a smaller one just below it, a larger and more prominent one around the 

 periphery, and three or four smaller ones on the anterior slope, besides 

 a spiral fold around the umbilical region; on the larger specimens there 

 are, sometimes, two or three strong, raised varices on the last whorl, and 

 the edge of the lip is thickened. The intervals between the carinas are 

 concave. On the preceding whorls the two larger carinne are visible, 

 often with a small intermediate one. The nucleus is minute, regular, 

 smooth, a little prominent. The rest of the shell is covered, between the 

 carinoe, with numerous, close, thin, obli(pie, raised lamellje, or lines of 

 growth; those on the subsutural band are flexuous. Aperture nearly 

 round; lip continuous; outer lip thickened, and with denticles exter- 

 nally, where the carinse terminate. Umbilicus spiral, very narrow, 

 sometimes closed. Color white. 



Length, 5.3™™; breadth, 4™™; length of aperture, 2™™.
