Part ii., 1884) and by Mr. R Lydekker (Cat. Foss. Mamm, Brit. 

 Mus., Part i., p. 176, 1885), it is also followed here. 



Mustcla martcs is found, at the present day, distributed over a 

 large part of Europe and Asia, and according to Mr. E. R. Alston 

 it is the only Marten known to occur in the British Isles. 



MUSTELA POTORIUS ? LINN JE US. 

 (Pole-cat.) 



There is in the British Museum a fragment of a right mandible, 

 from the Coralline Crag of Orford, which Mr Lydekker (Cat. 

 Foss. Mam. Brit. Mus., Part, i., page 179, 1885) identifies as 

 belonging to this species ; but there seems to be considerable 

 doubt as to its true age, for he says : " There does not appear to be 

 any evidence to show whether this specimen is a true Crag 

 fossil, or whether it has been introduced into that deposit." It 

 would be unwise therefore to accept this species definitely as a 

 Crag form until we have corroborative evidence. M. putorius is 

 known from Cave-deposits, but I am not aware of any other record 

 of its having been found in the Pliocene. 



The Polecat is now living throughout the northern parts of 

 Europe.

(Vert. Forest Bed, p. 17. PLATE VI., FIG. 1, la.) 



The presence of the Glutton in the Forest-bed was made 

 known in 1880 (Quart. Journ. Geol. Soc., Vol. XXXVI., Proceed- 

 ings, p. 99, and Geol. Mag. Dec. 2, Vol. VII, p. 424, Plate xv.), by 

 the finding of a portion of a jaw at Mundesley. The specimen is 

 in the collection of Mr. R. Fitch, at Norwich. 



The Glutton also occurs in British and European Cave deposits, 

 and at the present day is living throughout the northern parts of 

 Europe, Asia, and America.

The occurrence of the common Otter in the Norwich Crag has 

 been noted by Sir K. Owen (Brit. Fosti. Mamm., p. 121, 1846),
