W. D. ROEBUCK : LINCOLNSHIRE MOLLUSCA. 247 



In Mr. W. Nelson's collection there are specimens from Haxey, from 

 Ovvston, and from Scotton Common, and in Mr. Taylor's collection 

 are several specimens collected by Mr. T. Beaulah, the able and well- 

 known conchologist of Brigg 



For New Holland there is but a solitary book-record, and the 

 same is to be said of Bottesford. There is a single Scawby shell in 

 Mr. Thomas Rogers' collection, and several Brigg records figure to 

 the credit of Mr. Ball. For Brocklesby there is but one, a book- 

 record. Grimsby, Great Cotes, and Cleethorpes are represented by a 

 very few records set to the credit of Mr. W. Eagle Clarke, Mr. Kew, 

 and the late James Hardy of Manchester. For Caistor I have a single 

 record from Mr. W. Eagle Clarke, and for Gainsborough one from 

 Mr. P. F. Lee. We know nothing for the Market Rasen district 

 beyond a few large Helices brought for me from Glentham by 

 Mr. C. H. Bothamley. For Lincoln city and environs we have a few 

 records from various naturalists, including the Rev. W. W. Fowler. 

 For Skegness there are one or two records from Mr. C. T. Musson, 

 and fromWainfleet a single species was sent by the Rev. A. H. Cooke. 

 All these localities are in the Northern Division of Lincolnshire. 



The Southern Division has scarcely received attention at all. I 

 myself paid a flying visit of a few hours to Ancaster (near Sleaford) 

 on the 17th April, 1886, and there is a single book-record for the 

 neighbouring village of Honington ; and on the 7th March, 1887, 

 Mr. C. T. Musson paid a similar visit to Anwick, a village about as 

 far to the East of Sleaford as Ancaster is to the West; at both 

 places several species were met with. Grantham is represented — 

 in addition to the book-records — by a single record made by Mr. 

 R. Walker, of Leeds. In the extreme southern angle of the 

 county Mr. Edward Collier has collected several species at Uffington 

 (close to Stamford), and in July 1886, Mr. Thomas W. Bell brought 

 various water-shells from Crowland Wash. Between Lincoln City 

 and Bracebridge Mr. C. T. Musson collected a number of fresh-water 

 species from rejectamenta, in December 1884; and on the 8th 

 September of the same year Mr. Geo. Wingate and I spent a day 

 in collecting in the vicinity of Boston and Skirbeck, on both banks 

 of the Witham, and therefore in both divisions of the county. 



The present list is (so far as the small-type portion of it goes) 

 an 'authenticated' list. That is to say, it is an exact and literal 

 transcript from the record-books of the Conchological Society, and 

 all the records with the mark ! affixed have been authenticated or 

 verified as to specific determination by Mr. J. W. Taylor, one of the 

 Referees of the Society. The large-type matter is the genera- 

 lization based upon the small-type records which follow. In the 



Aug. 1887. ' -
