NOTES— CONCHOLOG Y. 



Planorbis complanatus var. submarginata in Yorkshire.— 



Of this variety of Moquin Tauclon's I collected about one hundred specimens on 

 September 30th, 1886. The shell is large; keel rather sharp, and placed a little 

 apart from the margin. The locality for this — which I suppose is new to York- 

 shire, if not to Britain — is Sharleston, near Pontefract. — Geo. Roberts, Loft- 

 house, Wakefield, October 19th, 1886. 



Addition to Wressle List of Mollusca.— Since the publication of 



my list Mr. Beanland has called my attention to a variety of SpJuvrium comeum 

 which was collected at Fleetdyke, in July 1886. The variety, which has been sub- 

 mitted to Mr. Cockerell, of Chiswick, turns out to be a new one to Britain. 



SpJmrium comeum var. regidaris Pascal. The description is, ' Regularly 

 globose, with yellow margin.' About six specimens were found, along with others 

 of the typical form. — Geo. Roberts, Lofthouse, Wakefield, October 19th, 1886. 



Cyclostoma elegans re-discovered in North Lincolnshire.— 



I have had the pleasure of re-discovering this shell in its old locality in the Louth 

 district, Burwell Wood, for which place the celebrated Dr. Martin Lister (who 

 was doubtless of the family of Lister of Burwell) recorded it in his ' Historiae 

 Animalium Anglire ' so long ago as 1678. The part of Burwell Wood in which 

 the species occurs is a valley with steep chalky sides known locally as ' Grisel 

 Bottom.' — H. Wallis Kew, Louth, nth September, 1886. 



Limax cinereo-niger at Shipley Glen.— Mr. J. A. Hargreaves, of 



Baildon, has sent me a fine specimen of the var. viaura of this species, which he 

 found under a stone in Shipley Glen, on the 30th of September, the same locality 

 in which Mr. West found the first Yorkshire specimen some years ago, the variety 

 on that occasion being hictuosa. — Wm. Denison Roebuck, Sunny Bank, Leeds, 

 October 6th, 1886. 



Estuarine Shells at Tetney, Lincolnshire.— On 12th July I had 



occasion to go to Tetney (near the mouth of the Humber), and was able to spend 

 a short time on the foreshore. Cardiwn edule L. was very plentiful, ' cockle- 

 beds ' extending for miles. Specimens of Mya arenaria L. were obtained from 

 some men who were digging them out of the clay, considerably above low-water 

 mark. The animals of this species are eaten by people living near the sea, under 

 the name of ' clams.' Liitorina rudis Maton, was taken from the muddy pools in 

 the saltmarsh. Littorina littorea (L. ) was extremely abundant all over the sand- 

 and mud-flats, often amongst Salicornia herbacea. Most of the specimens of this 

 shell were referred by Mr. Cockerell to the v. paupercula of Jeffreys. Hydrobia 

 tilvce Penn. was of course abundant. I searched for, but was unable to find, 

 Melampus myosotis (Drap.), which is recorded for Saltfleet on this coast. — 

 H. Wallis Kew, Louth, Lincolnshire, October 6th, 1886. 



NOTE— HYMENOPTERA. 

 Hymenoptera at Louth, Lincolnshire.— As the natural history of 



the county of Lincoln is so little known, it may be well, perhaps, to record the 

 following six species of Hymenoptera, which have been kindly identified by Mr. E. 

 Saunders, viz.: — Chrysis is^nita, Gorytes mystacens, Andrena albicrus, Andrena 

 albicans, Odynerus pictus, and Halictus subfascia/us, all taken in the Louth district, 

 1886. Mr. E. A. Eitch has kindly identified a specimen of Ichneumon trilineatus, 

 of which I found eight examples beneath the loose bark of two dead ash-trees in 

 Grisel Bottom, Burwell Wood, near Louth, in December 1885. — H. Wallis Kew, 

 Louth, Lincolnshire, 6th October, 1886. 



NOTE.— YORKSHIRE TOPOGRAPHY. 



The Rocks at ITlamborough. — Allow me to state — in reference to 

 the two pinnacles in Selwick's Bay, which are mentioned at p. 218 of the July 

 Naturalist as being unnamed, and for which names are there suggested — that ever 

 since I can remember they have been called Adam and Eve. — Matthew Bailey, 

 Flamborough, September 9th, 1886. 



Nov. 1886.
