178 PROCEEDINGS OF THE MALACOLOGICAL :>OCIKTY. 



her name and date, the said date being "May, 1840 ". This date 

 gives us the information that the book was published in or before 

 that month, which is exceedingly valuable, as previously no exact date 

 had been traced by me. Studying this work, I noted that on p. 74, 

 when Tritonidea was first mentioned, Swuiuson added a footnote : 

 "I have since learned that this genus is the same as Pollia, Gray, 

 a name I should gladly have adopted, had it not previously been 

 given to a genus of European Lepidoidera.^'' On p. 302, where the 

 genus is elaborated, a fuller explanatory footnote also appears to the 

 same effect, Hiibner and Treitseh being quoted as the authors of 

 tlie Lepidopteran genus. No such genus occurs in tScudder's 

 Komenclator, though tliere is a "• Folia,'' Ochsenh. Lep., 1816 A" 

 given on p. 257. This genus-name would appear to have been 

 proposed as a dedication of Poli, and would not seem to chish with 

 Gray's Follia, which I would guess to have been suggested by the 

 feminine name Polly. Gray also proposed Fannya and Emma, but 

 note my remarks re Gray under Modiolarca. 



Veloeita, Gray. 



Tliis name, generally quoted as Gray, 1840, is another of the 

 " Synopses B.M." names, where it is a nomen nudum. It apparently 

 dates from the Proc. Zool. Soc. 1847 article. Full details of these 

 papers have been given by me in these Proceedings (vol. x, pp. 294- 

 309, 1913). 



As a matter of fact, the name must be replaced by 



ViLLOEITA, 



as Griffith and Pidgeon, who contributed the molluscan portion of 



Griffith's edition of Cuvier's Animal Kingdom, vol. xii, had figured, 



on pi. xxxi, fig. 5, a shell under the. name Villorita cyprinoides, and 



on p. 601, in an Alphabetical List of the Figures, gave the further 



information 



"pi. 31, fig. 5, TiUorita cyprinoides, Gray. 



{^Cyrena cyprinoides, Wood) Olive Green." 

 A note is given, which reads : " Most of the inedited shells figured 

 in this work are from the collection in the British Museum." The 

 plate is dated 1833, whilst, as the title-page indicates, the volume 

 was completed in 1834. We can thus assume that as early as 1833, 

 Gray, after the custom of his time, had labelled the shell in the 

 l^ritish Museum with the name of Villorita cyprinoides, and that 

 Griffith and Pidgeon introduced this into literature. Seven years 

 later Gray apparently altered the spelling to Velorita, by which 

 name it has since been known. The spelling Villorita does not occur 

 in Scudder's Nomenclator, nor has it otherwise been recorded, though 

 Littoraria, introduced in the same manner and place, is duly 

 recorded. A peculiar circumstance has been noted, viz. that Fischer 

 in his Manuel (p. 1092, 1887) dates Velorita of Gray back to 1834, 

 which suggests that he had an inkling of Griffith and Pidgeon's usage. 



^ Huebner introduced it in 1806 as a nomen nudum, which was taken up by 

 Ochsenheimer in 1816 and Treitschka in 182.3. Polia was also proposed 

 by Cbiaje in 1827 for a member of the Order Vermes.
