RANDOM NOTES ON NATURAL HISTORY. 



was named for Prof. E. Linton, a member 

 of the Fish Commission parties of 1882 and 

 1883. A description of this shell will be 

 found in Am. Jour. Sci., Vol.xxiv, p. 365, 

 1882. No other specimen has ever been 

 discovered, to my knowledge, at least. Is 

 it entitled to a place among the shell-bear- 

 ing mollusca of R. I. ? 



Family 4. Buccinid^. 



See Random Notes, No. 6, p. 8. 



Sub-family 2. Neptuninse. 



Genus Neptunea, Bolten. 



Sub-genus Volutopsis, Morch. 



Yolutopsis Norvegicus, Chem. 



Dist., Newfoundland, Greenland, Ice- 

 land, Norway, Alaska, etc., etc. 

 Genus Sipho, Klein. 



Sipho pubescens, Verrill, sp. nov. Cat. 

 Mar. Moll., 1882, p. 501. Described by 

 Verrill as Neptunea propinqua. Am. Jour. 

 Sci., xvi, 210, 1878. Also, ib. xx., 391, 

 1880. Proc. U. S. Mus., iii., 370, 1880. 

 Inhabits deep water off Cape Sable to 

 Chesapeake Bay. A number of specimens 

 were dredged off Martha's Vineyard in 86 

 to 410 fathoms. 



Sipho Sabinii, Gray, 1824. 



Two specimens from Cashe's Ledge, 

 Maine. 



Sipho parvus, Verrill & Smith, sp. nov. 

 Cat. Mar. Moll., 1882, p. 504. Fourteen 

 specimens dredged off Martha's Vineyard 

 in 312 to 506 fathoms. 



Sipho glyptus, Verrill, sp. nov. Cat. Mar. 

 Moll., 1882, p. 505. Off Martha's Vineyard 

 in 219 to 458 fathoms. 



Sipho caelatus, Verrill & Smith, Proc. U. 

 S. Mus., iii., 369, 1880. Off Martha's Vine- 

 yard and Newport, R. I., in 238 to 500 

 fathoms. 



Still other species of Sipho are described 

 in the second Cat. of Moll., 1884, from 

 deep-sea dredging as deep as 2000 fathoms, 

 viz. : obesus, profundicola and var. dispar, 

 caelatus, var. hebes, caelatulus, simplex 

 and leptalaeus, the latter off Martha's Vine- 

 3'ard. One specimen only was found in 

 soft mud in 452 fathoms. Do these shells 

 belong to our fauna? 



Sub-Family 4. Buccinin.e. 



Genus Buccinum, Linn. 

 Buccinum Sandersonii, Verrill, sp. nov. 

 Cat. Mar. Moll., 1882, p. 490. Named for 



Mr. Sanderson Smith, of the U. S. Fish 

 Commission. Three specimens were dredged 

 off Martha's Vineyard in 258 fathoms. The 

 other species described are Buccinum cyan- 

 eum, var. perdix.. Cape Sable, Halifax, 

 Gulf of St. Lawrence. Buccinum tenue. 

 Gray, same localities. Tottenii, Stimp- 

 son, Newfoundland, Spitzbergen ; and a 

 few others from similar localities. 



Family 5. Nassid^. 



See Random Notes, No. 7, p. 8. 



Genus Nassa, Lamarck. 



Nassa nigrolabra, Verrill. Proc. U. S. 

 Mus., iii., p. 371, 1880. 



One specimen dredged off Martha's Vine- 

 yard in 155 fathoms, and referred to Nassa 

 provisionally. The animal is not known. 



Family 9. Marginellid^. 



See Random Notes, No. 8, p. 8. 



Genus Marginella, Lam. 



Marginella borealis, Verrill, sp. nov. 

 Second Cat. Moll., 165, 1884. 



A few dead specimens were dredged off 

 Martha's Vineyard in 65 to 100 fathoms. 

 It inhabits the warm waters of the Gulf 

 Stream, and is a strictly tropical or sub- 

 tropical genus. AVhy should we call these 

 Rhode Island shells 't 



Family 11. Columbellid.e. 



Genus Columbella, Lam. 



Sub-genus Anachis, H. and A. Adams. 



Anachis costulata, Cantraine. 



Dist., Norwa\', England, Nova Scotia, 

 Chesapeake Bay, etc. Dredged off New- 

 port in 1880 and 1881 in 146 to 506 fathoms, 

 (3,000 feet deep). 



. Anachis similis, Verrill. Rep. Invert 

 An., 1874. 



Syns.\ 



Columbella similis, Ravenel. Proc. Ac. 

 Nat. Sci., Phila. 41, 1861. 



Columbella avara (in part) Gould. Invert. 

 Mass. 



This species (avara) is described in 

 Random Notes, No. 9, p. 7. It Viiries very 

 much in form, sculpture, and color. Verrill 

 called the long and narrow varieties, 

 similis, and the others, avara. Other 

 authorities, having largequantities of speci- 

 mens from Massachusetts to Florida, have 

 decided that they are all one species, and 

 that one avara. I leave the subject here 

 without further remarks.
