tivation in the glens. Here and there ‘also,—e.g., in Glen Callater, 
on Little Craigandal, on Lochnagar, &c,—occur patches of alpine 
flora (descended from the flora of Britain during the Glacia 
Epoch) more or less associated with an alpine fauna. ; 
District No. 4 is a strip along the coast about five miles wide, 
by six miles from North to South. Along the shore stretch 
sandhills and links, diversified by small marshes here and there, 
and producing a rather peculiar fauna. This district is chiefly 
under cultivation, but has'some wood and moorland also. No. 
5 includes the rest of the valley of the Don, almost altogether 
lowland in character. Though pieces of woodland, as well as 
moors, occur here and there, yet as a whole it is under cultiva- 
tion. The upper part of the valley, viz, part of Strathdon and 
Corgarff, is sub-alpine, but information as to the fauna of that 
part is completely wanting. No. 6 is Buchan, exclusive of a 
strip, five or six miles wide, along the coast; it is mostly flat 
and well cultivated. My information as to this district is con- 
fined to that obtained from a collection of Lepidoptera made in 
the Parish of Fyvie (chiefly on the Braes of Gight), by Mr. Sim 
of Gourdas. 
No. 7 is the coast district corresponding to No. 6. As far 
North as Slains, and again at Crimond, the coast is sandy, as in 
No. 4; but from Slains to Peterhead, and again on the North 
Coast, it is rocky. For information about the fauna of this dis- 
trict I am indebted to the Rev. Mr. Yuill, F.C. Minister of Peter- 
head, in whose possession I saw specimens of the Lepidoptera, 
enumerated under that province, caught in the vicinity of Peter- 
head, or at Cruden. 
To Mr. Tait I owe most of my information regarding the Le- 
pidoptera of: No. 5, the list for which will be seen to be a good 
deal larger than that of any of the other districts. By far the 
greater number of the species have been taken by him in the 
vicinity of Inverurie. From him, also, I have obtained informa- 
tion in regard to the other districts, insomuch that the list of 
* species occurring in ‘Dee’ has been not a little enlarged by 
him, more especially among the Tortrices, of which the greater 
part have been added by him. I have also to thank him fora 
list from Mr. Carpenter of the species taken by the latter at Echt, 
while employed in the Observatory there. 
Mr. James Garrow also gave me valuable information, and 
favoured me with a sight of his collection of Lepidoptera, made 
at Inverurie. 
To Messrs. G. Sim, John Rae, and R. Gibb, members of this 
Society, and to Mr. A, Clark, in Old Aberdeen, I would express 
my obligations for valuable information, chiefly in regard to
