IKEDALE : ON NAMES OF BRITISH MAKINE MOLLCSCA. 341 



AZOR CHAMA-SOLEX (Costa). 



This -would appear to be the coi-rect name for the shell known as 

 Solecurtus (mtiquatus (Pulteney). Piilteney used it as of Solander, 

 and I find that in the Mus. Portl. Solauder's name was published 

 (p. 101, 1786), but ])rior to this date Costa had named the same shell 

 (Brit. Conch., 1778, p. 238: Weymouth), [Solen) chama-solen. This 

 specific name must be preserved, and it is not inappropriate when it 

 is remembered that Chama, Costa, was not Chama, Linne. Costa 

 used it for the Gapers, and if liis claim that the ancients so used it 

 be correct, it does seein inaccurately to have been bestowed by Linne 

 on a genus of shells noted for their tightly closed habit. 



The earliest introduction of Azov seems to be by Brown (Illus. 

 Conch. Gt. Brit., 2nd ed., 1844, p. 113) for this species alone. This 

 relieves the difficulty noted by me in this journal (vol. x, 1913, 

 p. 303). Anatomical examination has proved this species to differ 

 sufficiently for generic recognition from Solecurtus. 



Panomya arctica (Lamarck). 



This name will replace Panopea norvegica, Spengler, of the List. 

 Panomya was proposed by Gray (Fig. Moll. Anim., vol. v, p. 29, 

 1857) for the species Mt/a norvegica, Spengler (Skriv. natiirh. Selsk. 

 Copen., vol. iii, pt. i, p. 46, pi. ii, fig. 18, 1793 ; Norway). There 

 is. however, a prior 2hja norwegica, Gmelin, Syst. Nat., p. 3222, 

 1791, which appears in the List as Lyonsia norvegica, Chemnitz. 

 Gmelin's name depends upon Chemnitz's account given in the 

 Conch. Cab., vol. x, p. 345, pi. 170, figs. 1647-8, and is used as 

 Chemnitz was a non-binomial writer. The next name given to 

 the Panomya appears to be Glycgmeris arctica, Lamarck (Anim. 

 s. Yert., vol. v, p. 458, 1819: White Sea). Ball (Trans. Wagn. 

 Free Inst. Sci. Philad., vol. iii, p. 832, 1898) has shown the 

 necessity of using Panomya generically, but he overlooked the 

 invalidity of the specific name, calling the shell Panomya norvegica 

 (Spengler). 



OxiNA AURICULA (Turton). 



When Turton (Conch. Diet. Brit. Isles, 1819, p. 70) described this 

 species under the name Helix otis, from Devonshire, he added, "We 

 have been informed that it was known to the late Mr. Montagu, 

 who had intended to denominate it H. Auricula ; but as this name 

 approaches too near to auricularia, we have called it Otis.^' 



In making this alteration Turton selected a name used over thirty 

 years previously by Solander (Mus. Portl., 1786, p. 38) for a different 

 shell. We can then fall back upon the alternative name published 

 in the paragraph above noted. I have observed that Locard (Prod. 

 Malac. France, 1886, p. 88) introduced Oti7ia turtoni as a new name 

 for Otina otis (Turton), " Nom a changer par suite de pleonasme." 

 But in addition to the above, Brown had called the species Galericulum 

 ovatum (Illus. Conch. Gt. Brit., 1827, pi. xxxviii, figs. 27, 28), and 

 there is a varietal name Candida, Jeffreys.
