Jeffrey's Biitisli Conch., v, p. 99, pi. 4, fig. 1 ; pi. 97, fig. 5. — Verrill, Amer. 

 Journ. Sci., xx, p. 250, Sept., 1880. 



This was found iu July of this year, by the writer, living among decay- 

 ing sea-weeds, at high-water mark, between the docks at Newport, R. I. 

 It was associated with Alexia myosotis and Truncatella truncatula, and 

 was rather more abundant than either of the latter. Drawings of the 

 animal of this and the two species last named were made by Mr. J. H. 

 Emerton. The animal agrees well with the figures and descriptions of 

 the European examijles. It has not been recognized as American before. 



Eulinia intermedia Cantraine. 



G. O. Sars, op, cit., p. 210, pi. 11, fig. 20; pi. xviii, fig. 41. 



Several living specimens were taken at stations 870, 871, 874, 87G, and 

 877, in 85 to 155 fathoms. It has previously been known from deep 

 water in the Mediterranean, and off the Canary Islands, Lofoden Islands, 

 and Finmark (200 to 300 fathoms). 



This shell is more slender than E. oleacea. The sutures are not at all 

 impressed; the whorls are flattened so that the spire has a regular, 

 long-conical form. Aperture regularly ovate. The surface is smooth, 

 j)olished, and shining. Color of shell pure white, translucent; in life 

 the animal shows through, giving it a pale orange or salmon color. 

 Length, 5.G""^; breadth, 1.6'""'. 



Eulima distorta Deshayes. 



G. O. Sars, op. cit., p. 210, pi. 11, fig. 23. 



A single living specimen of this curious little shell was obtained at 

 station 871, in 115 fathoms. 



Turbonilla nivea Stimiisou, Check List. 



Chemnitzia nivea Stimpsou, Proc. Boston Soc. Nat. Hist., iv, p. 114, 1851 ; In- 

 vert. Grand Manan, p. 23, 1853. 



One perfect specimen of this very rare shell was dredged at station 

 871, in 115 fathoms. 



It is distinguished by its very slender, elongated form, with twelve 

 flattened, closely coiled whorls and slightly marked sutures. The 

 sculpture consists of well-marked, regular, transverse, rounded ribs, 

 with smooth interstices ; no spiral lines. Color white ; surface shining. 

 AjHcal whorl small, inciu'ved, and reversed. Length, 6.5""" j breadth, 

 1.5""". 



Turbonilla Rathbuni Verrill & Smith. 



Amer. Joum. Sci., xx, p. 398, Nov., 1880. 



Several fine living specimens were taken at stations 865 to 867, in 61 

 and 65 fathoms, and at stations 893 to 895, in 238 to 365 fathoms. 



Dedicated to Mr. Eichard Eathbun, of the United States Fish Com- 

 mission.
