Dentalium entalis (L.) Mighels (1843). 

 Entalis striolata, Stimpson (1851). 

 Dentalium entalis (L.) Pilsbry (1897). 



Grand Manan, " very common on muddy bottoms in the coralline zone " 

 (Stimpson). Passamaquoddy Bay and abundant almost everywhere on 

 muddy bottoms on the southern coast of New Brunswick (Ganong) ; 

 Annapolis Basin, two examples ( Verkruzen). Le Have Bank, Nova Scotia, 

 45 fiithoms ;gravelly and stony bottom, — and 60 fathoms, coarse gravel, 

 stones and sponges, abundant, — U. S. Fish Commission, 1872 (Smith and 

 Harger). 



" D. entalis is an abundant species on the coast of Maine ; and William 

 Stimpson, comparing with the European D. vulgare and finding differences, 

 distinguished the American shells as D. striolatum, under which name the 

 species is generally known in American collections. Had he compared with 

 D. entalis, the identity of the two would no doubt have been recognized. 

 There is no difference, not even varietal, between English and Maine 

 specimens. D. striolatum, or Entalis striolata of Jeffreys, Sars and Watson, 

 is D. occidentale, Stimpson " (Pilsbry).* 



Dentalium agile, M. Sars.

Dentalium occidentale, Stimpson. 



Dentalium dentalis, Gould (1841). 

 Dentalium occidentale, Stimpson (1851). 

 Dentalium abyssorum, M. Sars (1858) 

 Dentalium dentalc, Gould (1870). 



Living specimens of this shell were dredged by the writer in 1871, 1872 

 and 1873 in the deep-sea mud (150-313 fathoms) at several localities in the 

 Gulf of St. Lawrence, to the north and more especially to the south and 

 south-east of the Island of Anticosti. Writing in 1881, Prof. Verrill says 

 that it is "abundant on muddy bottoms, in 50 to 300 fathoms, all along the 

 coast of New England and Nova Scotia."
