interesting occurrences experienced, the time seemed not in- 

 opportune to write a short account of them, together with a list 

 of the mammals. Several new records are included, and it is 

 probable that the future will yield some others. I have been 

 fortunate in obtaining the help and advice of Messrs. Hutchings, 

 Taxidermists and Naturalists, of Aberystwyth. Through their 

 kindness I have been able to examine a very large number of 

 locally-killed animals in a fresh condition. I must also express 

 my thanks to the several gentlemen who have kindly supplied me 

 with information, and to Mr. W. E. Whitehouse, of the University 

 College of Wales, Aberystwyth, for his advice and assistance. 



Noeth Cardigan shike. — Topography. 



North Cardiganshire is bounded on the north by the Eiver 

 Dovey and the Afon Llyfnant, on the east by Plynlymon and 

 the western slope of the Central Plateau of Wales, and on the 

 south by the Wyre stream and the upper portion of the Eiver 

 Ystwyth. Its western edge forms the middle portion of the coast 

 of Cardigan Bay. The chief physical features which call for 

 notice in this area are briefly dealt with below. For the purpose 

 of this paper, however, it will be necessary to include a larger 

 area, although the greater number of the records fall well within 

 the limits described above. 



North Cardiganshire maybe divided into (1) the High Plateau 1 , 

 of the interior, and (2) the Coastal Plateau. A definite coastal 

 plain is absent in this county, and the only low-lying land 

 fringing the coast is the large marshy tract of Cors Fochno, now 

 better known as Borth Bog. This forms the south shore of the 

 great inlet of the estuary of the Kiver Dovey, in the extreme 

 north of the county. Borth Bog is composed of a substratum of 

 glacial drift overlain by considerable deposits of peat. Apart 

 from the fact that it furnishes some peat fuel to the district, and 

 also affords pasture to a few sheep, it is little used and rarely 

 frequented. It supplies a refuge and breeding-place for various 

 birds and mammals. 



The Central Wales Plateau consists of that land which may 

 be described roughly as exceeding 900 ft. in altitude, and cul- 

 minating in the Plynlymon ridge in the north. A great part of 

 the moorland comprising the High Plateau is uninhabited, and.
