lEEDALE : ON NAMES OF BRITISH MARINE MOLLUSCA. 335 



described the shell as Turritella? costiilata, it not being Lamarck's 

 nor Risso's so-called species. But the present species is not 

 a Turritella (as, indeed, Miiller suspected) : and the reason assigned 

 by Murch is, therefore, insufficient. I described the fossil shell as 

 Ceritltiopsis nivea^ and S. P. Woodward proposed to name the recent 

 one Cerithiwn Naiadis.^'' This passage might be cited as a perfect 

 example of liow 7iot to make conchological literature. There is not 

 a single reference given, and the attempted recovery of such has 

 entailed so much labour that I here record my results as an aid to 

 future investigators. Morch changed the name in Rink's Grenland, 

 Band ii, Nat. Bidr., p. 82, 1857, because lie transferred the species to 

 Cerithium, according to some writers. I have been unable to find 

 Turritella costulata in Lamarck's.^writings, nor does E-isso give such 

 a species as far as I can discover."^ Xo reason was assigned \>x Miirch, 

 his words being " Cerithium arcticam, noh. Turritella? costulata, 

 M0II. nee. Lam. nee. Risso ". Such an entry suggests what Jeffreys 

 wrote, but it was his duty to verify the facts before endorsing the 

 statement. In the Ann. Mag. Xat. Hist., ser. in, vol. iii, p. 53, 

 pi. iii, figs. 17«, h, January, 1859, Jeffreys described C{erithiopsis) 

 nivea from the Turbot Bank, Belfast Bay, with no intimation that it 

 might be fossil. In the same place he recorded C{erithiopsis) naiadis 

 from Zetland as " Mr. Woodward has undertaken to describe it, with 

 other Norwegian shells, in the ' Annals' ". I have searched this and 

 every other source I can think of, and have been compelled to con- 

 clude that the last-named lias never been described and is still 

 a noriien nudum. In the British Museum there is a shell, presented 

 by R. McAndrew, labelled in his handwriting " C. naiadis^ Wood- 

 ward MSS. Finmark, R. Mc." 



Geaphis, Jeffreys. 



Cioniscus, Jeffreys, must be abandoned in favour of this name. 

 Graphis was proposed (Brit. Conch., vol. iv, p. 102, 1867) for tinica, 

 '^lowt. = alhidus, ' G. Adams.' In the next volume, p. 210, 1869, 

 Jeffreys replaced Graphis by Cioniscus, as he had noted that Graphis 

 was preoccupied in Botany. Botanical names do not now concern us, 

 and I do not find that Graphis was anteriorly used in Zoology, so 

 that we must revert to Jeffreys' first nomination. 



RissoiD Names. 



I am now engaged upon these, and I find that there is jrreat 

 confusion. So far I note the following cannot be maintained : Rissoa 

 albella, Loven, Alvania reticxdata (Montagu), Ilanzonia costata (J. 

 Adams), Onoba striata (J. Adams), Barleeia rubra (Montagu), and 

 probably Galeodina carinata (Costa). 



Family PYRAMIDELLID^. 



In the List twelve generic groups are admitted. Dall & Bartsch 

 issued as U.S. Nat. Mus. Bulletin, No. 68, December 13, 1909, 

 a Monograph of West American Pyramidellid Mollusks, and therein 

 gave a Synopsis of the Genera, Sub-genera, and Sections. Following
