APPENDIX. 309 



3. S. fodiens, Gmel. Water Shrero. Deep 

 brownish-black above, nearly white beneath, the 

 two colours distinctly separated on the sides ; feet 

 and tail ciliated with white hairs. 



This is the species described under the same 

 name at p. 126 of this manual. 



4. S. ciliatus, Low. Ciliated Shrew. Black 

 above, greyish-black beneath; throat yellowish- 

 ash ; feet and tail strongly ciliated with greyish 

 hairs. 



The Oared Shrew, S. remifer, described at 

 p. 130, is the same as the present. 



Including Sorex Utragonurw, and rejecting the 

 Beech Marten and Black Water Vole as species 

 distinct from the Pine Marten and Common Water- 

 Rat, as well as Plecotus brevimanus, which is 

 supposed to be specifically identical with P. auritus^ 

 we thus find that the number of British Quadrupeds 

 is fifty. Although their habits cannot so easily be 

 studied as those of birds, nor specimens of many 

 species readily procured in any particular district, 

 they constitute a most interesting portion of our 

 Fauna, the complete elucidation of which is yet a 

 desideratum in our scientific literature. The Bats, 

 Shrews, Seals, and Mice, are the groups in which 

 discoveries more probably remain to be made.
