BYNE: PKEVENTION Of CORROSION IN SHELLS. 361 



sublimate (mercuric chloride), but this is cumbersome. I find it a 

 good plan to take the drawers out of my cabinet about once a month 

 and leave them in the air for a day. This does away with chance of 

 mustiness and damp. I have a great objection to the smell of oil 

 of cloves, and should never use it. I shall be pleased to receive 

 criticisms or suggestions.

Acanthinula lamellata (Jeff.) at Grange-over-Sands, Lanes., and Notes 

 on various other Species. — In the middle of October last I paid a visit to Grange- 

 over-Sands, and in company with Mr. J. D. Dean further explored that conchologist's 

 paradise, Eggerslack Wood, in the hope of increasing my set oi Aciciila lineata, of 

 which I took three specimens in 1903. The weather was anything but congenial, 

 heavy showers being the order of the day, and as the few previous days had been 

 very cold, a big " bag " was hardly to be expected. Under these unfavourable 

 conditions I set to work to search the moss and dead leaves, when to my surprise, 

 instead oi Acictda I found a living full-grown Acanthinula lamellata under a dead 

 branch of elm, the nearest holly being ten yards away. This, I find, is a new record 

 for District 69. As I have always associated holly leaves with this species, having 

 taken it amongst them in Ireland, I commenced to hunt amongst the dead leaves 

 strewn about, but failed to discover any more specimens. I also tried other hollies 

 further up the wood, but with no better success. Here, however, Euconulus fulvus 

 and Acanthinula aculeata were common on dead holly leaves. Slugs were com- 

 mon in many parts of the wood, Agriolimax agrestis, Arion ater, A. hortensis, 

 A- minimus, Limax inaximus, and L. arborum being the chief species. At one 

 place I noticed a fine specimen of Arion ater var. alba on the same stone as a 

 typical specimen. Shells on the whole were scarce, the absence of otherwise com- 

 mon species being noticeable. Even Vertigo alpestris — an abundant shell here — 

 only occurred in small numbers on the walls surrounding the wood. V. pusilla 

 occurred sparingly. Clausilia bidentata and CI. laminata were fairly common on 

 dead logs and climbing up trees. Jaminia cylindracea was, as usual, very prolific. 

 So also was Pyj-amidula rnpestris. 



Leaving the wood I went in search of Helicella caperata, which, with its var. 

 ornata, I found common on the cliffs on Lindale Road, and swarming over the 

 wet rocks and herbage at the foot of the same. Amongst the herbage there was a 

 quantity of tansy, and I have observed a partiality for this plant on the part of 

 H. caperata in other localities. Most of the shells here were full grown and of a 

 large size, and with them were many immature Hygromia rufescens and Vitrea 

 cellaria. The latter species, however, was not so active as fl. caperata. It was on 

 these cliffs that I found a couple of specimens of Vitrea liicida in 1903, and as no 

 further specimens rewarded my search, and not having heard of any having been 

 taken there since, I have come to the conclusion that my specimens must have 

 arrived there with greenhouse refuse, most probably thrown down from gardens 

 above. As H. caperata proved so plentiful here, I was led to try the colony of 

 Poinatias elegans about a mile and a half along the Meathop Road, but notwith- 

 standing my most strenuous efforts, I failed to find a single specimen either young 

 or old. It seems a remarkable thing that this apparently well-protected shell 

 should disappear in this way early in the autumn, and as I had the same experi- 

 ence at Silverdale last autumn, I should like to know whether this is general 

 throughout the country. At both the above places the shells are quite common 

 during the spring and summer. — ^J. Wilfrid Jackson {Read before the Society,
