90 PROCEEDINGS OP THE MALACOLOGICAL SOCIETY. 



Arenaria and Marginelligenus, Marginella, Cystigenus, Gystia, 

 Imisigenus, Imisia, Planospirigenus, Planospira, quoting the last 

 as of Fan j . He also included Lamarck's Marginelligenus, Marginella, 

 but bis own name was given to a bivalve placed between Plancuna 

 and Lima and followed by Pedum, Gystia, and Imisia. Renier also 

 includes his Mollusca, previously placed under Vermes, in this class 

 Molluschi. 



The reference of many names to Renier appears to be based on 

 essays by Nardo, but of course the names can only be attributed to 

 the later introduction, and cannot be carried back to the date of 

 Renier, when they are not recognizable by the data given by Renier 

 himself. Thus Tellina serrata Renier appears as a doubtful 

 constituent of the British fauna, but Tellina serrata Renier is a 

 nomen nudum ; a second instance is Solen candidus Renier, often 

 quoted in connection with Solecurtus scopula, Turton, but now 

 rejected, which also proves to be a nomen nudum in Renier. 



Reeve's " Elements op Conchology ". 



In these Proceedings, Vol. XII, 1916, p. 44, Reynell gave some 

 notes concerning the first publication of this worlc. He pointed out 

 that ten parts came out, then ten years elapsed and then six more 

 parts completed the work. He gave the title-page and contents of 

 the parts and dates of publication as then known. I have now 

 procured the original ten parts as issued complete save the 

 front wrapper of part ix. The advertisements on the wrappers prove 

 to contain much information of value. Thus on the wrapper of 

 No. 1 is published : " To be completed in Twelve numbers. No. 1 

 on the 1st of March," and includes the title-page " Initiamenta 

 Conchologica. 1846 " and the preface dated Feb. 20, 1846. 

 The wrapper of part iv bears different advertisements " in twelve 

 monthly parts " " three of which are now published." On 

 the wrapper of part vi the same appears, but an inset states 

 " a moiety is before the public ". Advertisements of the " Con- 

 chologica Iconica " provide better data, as it is stated that this 

 was " Published monthly on 1st day of every month, the first part 

 on Jan. 1, 1843 ", and this appears to be correct. From criticism 

 of these and other announcements, it appears that the " Elements " 

 soon suffered for I reckon out the dates of publication approximately 

 as follows : Pt. i, 1st March, 1846 ; Pt. ii, 1st April, 1846 ; Pt. iii, 

 1st May, 1846 ; Pt. iv, June, 1846 ; Pt. v, July, 1846 ; Pt. vi, 

 December, 1846; Pt. vii, May, 1847; Pt. viii, January, 1848; 

 Pt. ix, August, 1848 ; and Pt. x, January, 1849. 



It is fortunate that the names are practically all nomina nuda, 

 the few requiring attention being those of the figured specimens. 

 No species credited to Reeve himself appears until Part v, when 

 Cyllene grayi, p. 65, pi. iii, f. 12, and Phos cumingii, p. 67, pi. iii, 

 f . 16, are included. In Part vi Oriecia dennisoni, p. 84, pi. vii, f. 35, 

 is figured.
