206 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY. 



Apparently Scudder saw a copy and collated the names which he 

 claims and cites " Fortegn, 1822 " ; the other names are included 

 from the Agassiz MS., and in two instances duplications occur as 

 Pugilis for Pugil and Labrata (^ Calyptrcea) for Labiata. 



Neptunea, Bolten. 



I herewith designate as type of Neptunea, Bolten, Mus. Bolten, 

 p. 115 (pref. Sept.) 1798, the first species N. despecta, Bolten based 

 on Martini 4, t. 138, f. 1296. 



In view of Dalls' recent transference of Bolten's name from the 

 shells with which it had been associated for from fifty to seventy 

 years without question, to another well-known series with which it 

 had never been considered until 1902, I have searched through the 

 literature in an efiort to find a legitimate type designation which 

 would enable a definite settlement. I found that all the leading 

 conchologists, whether British, Continental, or American, had 

 continually used Neptunea, when their attention was drawn to it, 

 in the sense above designated, and had cited as exami^les the shell- 

 form I have named. The above definite designation will, I hope, 

 place their action beyond dispute, and is in agreement with the 

 opinions of the International Commission on Zoological Nomen- 

 clature, that a rigid observance of the rules of type-selection is 

 absolutely necessary in doubtful cases. 



SiPIIONAEIA GRISEA vice S. ALGESIR^, Q. & G. 



In 1833 Quoy and Gaimard described a Siphonaria from the 

 Straits of Gibraltar in the "Voy. de I'Astrol", vol. ii, p. 338, as 

 S. algesirce, and it was figured on pi. xxv, figs. 23-5. It is fairly well 

 known under that name, but appears to have been named many 

 times previously, and also since. 



Blainville, in the " Diet. Sci. Nat." (Levrault), vol. xxxii, p. 267, 

 13th November, 1824, admitted Sowerby's genus Siphonaria, and 

 recognized the shell figured by Adanson under the name " Mouret " 

 as a member of the genus. He proposed to name it Siphonaria 

 mouretus. 



In the following volume, published 22nd January, 1825, Blainville, 

 p. 161, introduced the genus Mouretus for the Mouret of Adanson 

 (" Seneg.," p. 34, pi. 2), naming the species Mouretus adansonii. He 

 here stated that his genus was identical with the prior Siphonaria 

 of Sowerby, and in vol. xlix, published on 13th October, 1827, he 

 monographed the genus Sip)honaria, exj^laining : " Adanson . . . 

 designee sous le nom de mouret ; aussi depuis longtemps, dans mon 

 Genera, envoye en Angleterre en 1816, pour le supplement a 

 1 'Encyclopedic d'Ecosse, je I'avois separee pour en constituer un 

 genre distinct, auquel je conservois cette denomination." On p. 295 

 he named the species Siphonaria adansonii. About the same time, 

 in the Tankerville Coll. Catalogue, published in January, 1825, 

 Sowerby introduced (p. 32) Siphonaria mouret for " Mouret 

 Adanson."
