70 THE SCOTTISH NATURALIST 



Bittern in the Island of Lewis. On the 30th of January 191 7, 

 a Bittern (Botaurus stellaris) was found in an exhausted condition 

 at Carloway, Loch Roag, on the west coast of the Island of Lewis. 

 It was sent to me by the schoolmaster there, Mr M'Donald, 

 and by me to the Royal Scottish Museum. It is the only one 

 known to me as having occurred in the island, though Saunders 

 in his Manual states they have been found in the Outer Hebrides.

[This appears to be the fourth recorded occurrence of this bird 

 for the Outer Hebrides. There are two former records for North 

 Uist (one without date and one about 20th April 1915), and one for 

 Harris, where a Bittern was obtained in January 1890. Eds.] 



Little Gull in the Tay Area. On 6th October 19 16 we saw 

 a Little Gull (Lari/s minutus) on the shore a little to the south of 

 Kingsbarns Harbour (Fife). It was an adult in winter plumage, and 

 in spite of strong west wind and driving rain we had an excellent 

 view of it, first as it stood on the shore among some Black-headed 

 Gulls, and later when it flew past us only a few yards off. Evelyn

Milax sowerbyi in Main Argyllshire. Mr William 

 Rennie, of Glasgow, has sent me a number of Slugs collected at 

 Kirn on the 4th January 191 7, the first molluscan work of the 

 new year, and including a species {Milax sowerbyi) which is 

 additional to the Main Argyllshire list (see my paper, Scottish 

 Naturalist, September 1916, pp. 229-239). It is also a notable 

 extension of the range of the species northwards, being the most 

 northerly habitat so far known for the western side of Scotland, 

 though on the eastern we have it recorded as far as Aberdeenshire 

 South. This specimen is a very minute young one, though 

 perfectly unmistakable and characteristic. It was with abundance 

 of Agriolimax agrestis in both its main forms, var. pallida and 

 var. reticulata, the latter much predominating, a few Arion hortensis, 

 and one exceedingly juvenile, A. circumscriptus, all amongst rubbish 

 along the shore beyond high-water mark, partly covered with wrack 

 and exposed to the wash of sea-water. From gardens came 

 abundance of A, hortensis, and of Agriolimax agrestis var. 

 reticulata, which may be regarded as the dark and maculated or 

 winter form, the type form pallida being more abundant in summer. 

 From the gardens also was sent a fine adult Limax arborum var. 

 bettonii, and from the wall of a built-up spring well an exceedingly 

 large specimen of L. maximus var. obscura ; this was very dark in
