At Southampton it occurs with two varities griseus Moq, and 
coeruleus, Cllge ; and is widely distributed in Somersetshire. 
Being very perplexing, owing to the young differing so markedly 
from the adult form, Coll in ge has given a synopsis in his review 
of the Arionidse, showing its anatomical differences in comparison 
with A. bourguignati; and enumerates six varieties. Var. albipes, 
Ckll, is probably only an immature example of the type,” and var. 
fallax Ckll, is a minor subfuscus. Why is the var : caeruleus, 
Cllge, omitted in the recent list published by the Conchological 
Society ? It might even prove to be a distinct species. 
Arion Celticus, Pollonera. 
Another addition to the British List. I found it at Southamp¬ 
ton conjointly with the find of Arion cottianus and in the same 
locality, and thought, at that time, the two species may have 
been recently introduced, being brought in earth, or among 
plants, but, as I afterwards found A. celticus at Doddington, Kent, 
both species may possibly be found in many other localities in 
the southern counties. 
It is doubtful if the anatomical differences of Pollonera’s A. 
celticus are constant enough to warrant it with specific distinction. 
That author figured and described it in 1887, but Dr. Simroth has 
examined specimens, and thinks there is no difference between it 
and A. hortensis.

FIELD CLUBS AND SOCIETIES. 
Lambeth Field Club. —March 19.— At this meeting, Mr. F, P. Perks 
read a paper on “Naturalists and Nature Lovers,” the conclusion arrived at 
being that the blending of these two (often antagonistic) types in one individ¬ 
ual produced the greatest amount of enjoyment in the study of nature. This 
was fol}owed by a paper on “ Limestones,” by Mr. W. B. Baskerville, in illus¬ 
tration of which several specimens were passed round for inspection. Mr. 
Baskerville also exhibited some acorns of Quercus cegilops, from the Levant. 
The president, Mr. George Masters, then read somenoteson Sun ey archaeology. 
He called particular attention to the Roman occupation of Surrey. April 2.— 
A wellillustrated lecture was given on this date, by Mr. C. H. Holden, entitled 
“A Ramble in the Woods; or, Timber and Timber Trees.” Air. Holden is 
a great authority on trees, so his lecture was much appreciated by those present, 
including several visitors. He first pointed out the importance of the study of 
forestry to the human race, though from one circumstance, namely, the substi¬ 
tution of iron tor wood in ship-building, its importance was not now so great. 
When oak was in vogue for ship-building, 14,000 cubic feet of wood, requiring 
2,200 full-grown trees, went to make one vessel. Nowadays, oak had fallen 
in value, and a great deal came from abroad. Details were then given of the 
Winfarthing oak and some other great trees, and after this came an interesting 
account of the processes through which wood had been passed by an ingenious 
German, in order to form it into a palatable kind of bread. The experimenter 
generously allowed a young dog the first bite at this, as it turned out, nutritious 
product. The “ cow-tree ” of S. America, was next described by the lecturer,
