IKEDALE : ON INVALID GENERIC NAMES. 171 



every page, wherever many names occur, I note unrecorded examples. 

 As above stated, through the general usage of malacologists of 

 Fischer's Manuel, we have not felt this omission deepl}-, but it is 

 probable that other branches will have suffered, and I note Agnesia 

 included in the Index Zoologicus as having been introduced by 

 Michaelsen in 1898 for a Tunicate. The reverse case of course affects 

 us, i.e. that names proposed in other classes of zoology have likewise 

 been omitted from the Index Zoologicus, and that such may invalidate 

 apparently unassailable names given by malacologists. I cannot 

 suggest any remedy to provide for the protection of malacologists in 



such instances. 



Adeoebis, Searles "Wood. 



In these Proceedings (vol. ix, p. 259, 1911) I published a note 

 drawing attention to Sacco's usage of '■'• Tornus, Turtoii, 1829", in 

 place oi Adeorhis, Searles Wood, 1842, and asked for confirmation or 

 otherwise. An immediate result was the receipt from Dr. W. H. 

 Dall of a reference to British Conchology, vol. iv, p. 231, 1867, 

 where Jeffreys wrote: "Searles Wood was anticipated in giving 

 a name to the present genus. In an ' Enumeration of Marine Shells ' 

 found on the South Devon coast, published in 1829 (a copy of w^hich 

 was presented to me by Dr. Turton ' froiu the author'), the genus 

 Tornus, signifying a turner's wheel or lathe, was characterized as 

 follows: — 'Shell orbicular, depressed, aperture oval or roundish; 

 pilhxr none. Operculum horny. Includes Helix suhcarinata.^ This 

 publication was anonymous, a circumstance which may deprive the 

 author of the right of precedence according to the laws of scientiiic 

 nomenclature. I therefore retain Adeorbis, although the other name 

 is preferable." 



At that time 1 could not trace the publication Jeffreys mentions, 

 so the matter had to be shelved. Consequently Hedlej', introducing 

 the new genus Naricava (Proc. Linn. Soc. N.S.AV., vol. xxxviii, 

 p. 294, 1913), commented: "It has been indicated by Iredale that 

 Adeorbis may be replaced by Tornus, but this is not established." 

 It is with very great pleasure that I now complete my tale, and 

 eliminate all doubt concerning the genus-name Tormis. 



As long ago as 1903 Mr. B. B. Woodward had seen this name, but, 

 comparatively uninterested in marine shells, had failed to note its 

 significance. I obtained my clue from a footnote published by him 

 in the Journ. Conch., vol. x, p. 359, 1903, with regard to the 

 genus-name Odontostoma. There will be found details practically as 

 here given. 



A book entitled The Teignmouth, iJawlish, and Torquay Guide, by 

 N. T. Carrington and others, was published at Teignmoutli, and also 

 sold at Exeter, London, etc. Part ii bears on the title-page "The | 

 Natural History | of | the District ; | or, | Lists | of | the different 

 species | of | animals, vegetables, and | minerals, | and their respective 

 localities, | scientifically arranged ; | with References to the best 

 Standard Works in which | they are figured and described: | together 

 wdth I a Geological Account | of | the rock strata, and the fossils | 

 contained in them. | By | AV. Turton, M.D., and J. F. Kingston."
