THE recorder's REPORT. 



Mr. Wm. Denison Roebuck presented his report as Recorder 



of the Society of the Yorkshire localities of shells, which is 



appended hereto : — 



" The Recorder of Yorkshire Localities has to report that 

 during the year 1880 specimens have been shown at the meetings 

 in authentication of 204 localities for 58 species and varieties of 

 land and freshwater shells. The numbers at present standing on 

 record in the books, including the entries made not only in 1880 

 but in all preceding years, are: — 1,104 records for 12S species 

 and varieties, giving an average of rather more than eight records 

 for each form. Four species and varieties have been shown 

 during the year for the irrst time. The Recorder would conclude 

 by reminding members and others that the aim of the Record 

 Book system is to afford a well authenticated source of informa- 

 tion on geographical distribution. To this end no record is 

 admitted unless the specimens are shown at the meetings, and 

 the determination verified by competent authority. For the com- 

 plete attainment of this object the co-operation of all collectors 

 is needed. Instead of the localities averaging eight for each 

 form, there should be hundreds ; and shells from every part of 

 Yorkshire, of all species, even the commonest, should be sent 

 for exhibition, and for the furtherance of a scientific object which 

 is so well carried out by the Botanical Record Club." 



LYMN^A PEREGRA var. PICTA, IN DERBYSHIRE. 



By Rev. HERBERT MILNES, M.A. 



In one of my conchological excursions in the North of 

 Derbyshire, I dredged from a small pool in the neighbourhood 

 of Winster several specimens of Lymnaa peregra var. picta. As 

 I am not aware of its being recorded as taken before in Derby- 

 shire, I have thought it might interest some of the readers of the 

 Conchological Journal to hear of its occurrence.
