NOTES on MOLLUSCA. 



Helcion pellucidum in Cumberland. — As very few records exist of 

 Cumberland marine mollusca, it may be of interest to record two examples 

 of this shell found among - seaweed between Parton and Harrington. — Jas. 

 Murray, ii, Close Street, Carlisle, 23rd February 1901. 



Trochus zizyphinus var. lyonsii on the Yorkshire Coast.— This 

 Trochus is not common on the Yorkshire coast even in the type form, and 

 the albino variety [lyonsii) appears to be exceedingly rare. I found a fine 

 live specimen in the South Bay at Scarborough last Monday, 4th February, 

 the first I have ever come across on this coast.— W. C. Hey, West Ayton, 

 Yorkshire, loth February 1901. 



Albinism in Mollusca at Hubbard's Hill, Louth. -The following 

 examples of albinism (species and varieties) were collected at Hubbard's 

 Hill during the season 1900 : — 



Hyalinia pura var. margaritacea. Fairly common. 



Hyalinia crystallina. Common. 



Helix pulchella. Common. 



Helix arbustorum var. albino,. One specimen. 

 Helix rnfescens var. alba. Two specimens. 



Helix ericetorum var. alba. Fairly common on the slope at the S.W. end. 



Bulimus obscurus var. albina. Fairly common. I have seen these some 

 15 to 20 feet from the ground on the trunks of the ash trees. They 

 are generally coated with mud, resembling the bark of the trees, 

 therefore requiring careful search. 



Achatina acicula. Three specimens. 



Carychium minimum. Common. 

 — C. S. Carter, 172, Eastgate, Louth, 9th April 1901. 



North Lincolnshire Slugs.— Arion ater and one or two of its varieties 

 are still very common at Bottesford, while at Cadney I can only find the 

 type. Limax maximus was fairly common 35 years ago under water tubs 

 and stone troughs, but my brother Max could not obtain a single specimen 

 last season where we had the type and at least one variety in confinement 

 years ago. When I was about 14 years old, in moving an old tree that had 

 blown. down and been left for many years, we found an albino specimen of 

 this species. It was of full size and milk white, without any darker lines 

 at all. Limax flavus was rare but seen by us most seasons as children. 

 I cannot remember ever having seen a variety of this species. We tried to 

 keep the type in wooden boxes, but if I remember rightly did not succeed 

 with it. We used to find Agriolimax Icevis Miiller under the Pink [Dianthus] 

 roots in the garden. A. agrestis was everywhere. There were other 

 species, Arion minimus I am sure from the description in Adams' Collector's 

 Manual, but at this distance of time though we kept them in boxes to 

 breed them I cannot be sure. Bottesford is the best neighbourhood for 

 slugs — or shall I say the worst? — I have ever known. — E. Adrian 

 Woodruffe-Peacock, Cadney, Brigg, 22nd April 1901. 



NOTES AND NEWS. 



We learn from the publishers that a work on 'Our Country's Shells : 

 a Guide to the British Mollusca ' is in the press. This is a new volume in 

 'Our Country's' series of which flowers, birds, butterflies, and moths have 

 already become recognised handbooks. It is an entirely new work on 

 a scientific basis, but of quite a popular nature. There are to be 33 full- 

 page coloured plates of over 600 examples, illustrating every native species, 

 and the text is further illustrated with many original diagrams of the 

 structure of the shells and their inhabitants. It will be issued shortly by 

 Simpkin, Marshall & Co., and the price will be (>s. The author's name, 

 a matter of importance, is not stated, and we venture to hope thai the 

 volume will be by a really competent hand, and not merely by a book-maker.
