106 ANNALS OF SCOTTISH NATURAL HISTORY 



Arion minimus, but this has already been recorded in my 

 census. 



3. Banffshire Slugs. — I have to report four additional 

 species of slugs for Banffshire, making its total list amount to 

 23, a small figure as yet. These are Arion ater, represented 

 by a couple of immature examples ; A. subfuscus, several 

 adult, some deeply and richly coloured ; A. minimus, in great 

 abundance and of all ages to adult ; and several Limax 

 arborum, adult and young. Specimens of the already re- 

 corded Limax agrestis and Arion bourguignati accompanied 

 the newly recorded species. All these were found by Mr. 

 Wm. Evans on the banks of the Avon, above Ballindalloch. 



On the 1 ith September Mr. Evans sent me a consignment 

 of slugs from Tomintoul, a very out-of-the-way place, the 

 slugs of which it is well worth while to record. They were 

 a fine adult and a young specimen of Limax maximus, var. 

 fasciata, a half-grown Arion ater, several fine A. hortensis, 

 and several not quite mature examples of A. bourguignati. 



On the 1 7th of July 1891 I had the pleasure of receiving 

 from the Rev. George Gordon an example of Limax cinereo- 

 7iiger, about three-quarters grown, with the keel-line dull ochre 

 and a pale stripe down each side, together with a small and 

 very dark L. arborum, var. alpestris, which he had found under 

 the decayed and loosened bark of an old fallen birch-tree, 

 some hundred yards south of the Duke of Richmond and 

 Gordon's shooting lodge at Glenfiddich, Banffshire, and about 

 800 feet above sea-level. This fine species, which is in these 

 islands a particularly northern and western form, is an im- 

 portant addition to the Banffshire list. 



4. The Tree-slug* in the Outer Hebrides. — It is to my 



old friend, Mr. W. Eagle Clarke, F.L.S., that I am indebted 

 for the next record that I have to make, viz. that of a very 

 dark example of Limax arborum from the Shiant Islands, an 

 outlying group of the Outer Hebrides, which brings the 

 Hebridean authentications up to 16 species. 



5. Faunal Status of Limnaea stagnalis in Scotland. — 



Since the publication of my paper on the introduction of this 

 species into Lanarkshire, I have had placed in my hands two 

 letters bearing on the topic addressed to Mr. Clarke. The
