YORKSHIRE VERTEBRATE FAUNA. xxxi 



ever truly wild. The Red Deer also is now only in parks, but its 

 claim to be considered indigenous is valid, for there can be little 

 doubt that those at Bolton and Wharncliffe are descended from 

 the aboriginal wild stock once frequenting those districts. 



The remainder of the terrestrial species do not call for much 

 remark, save that the Noctule or Great Bat and perhaps one or 

 two other bats find in Yorkshire the northern limit of their range 

 in Britain. In stating the faunistic position of terrestrial mammalia, 

 it has not been considered necessary to use the word 'resident/ 

 inasmuch as all the species perforce come under that category. 



Of the fourteen marine forms two are Seals, the remainder ceta- 

 ceans. Both the Seals are now very rare casual visitants, although 

 it is not a great number of years since one of them, the Common 

 Seal, was quite an abundant resident at the Tees mouth. Of the 

 twelve cetaceans the Porpoise only can be considered abundant, 

 although the Grampus and possibly the Lesser Rorqual are of 

 not uncommon occurrence ; the other species having occurred 

 as stragglers only. No doubt other whales than those recorded 

 visit the Yorkshire seas, but in the absence of evidence of their 

 being examined by competent authorities the numerous 'finners,' 

 'grampuses,' and 'bottle-noses' reported in the newspapers from 

 time to time must remain in obscurity. 



The twenty-three British species which have not been found in 

 Yorkshire include but one terrestrial form, the Varying or Moun- 

 tain Hare, an animal which does not occur in Britain south of the 

 Scottish highlands. The remainder are bats, seals, and cetaceans. 

 Of the nine bats a group which receives very scant attention 

 and offers a wide field for research there can be little doubt that 

 other species remain to be discovered in Yorkshire. This is 

 demonstrated by the fact that the present work is the means of 

 adding an hitherto unrecorded form the Whiskered Bat 

 to the Yorkshire fauna. Daubenton's Bat which has indeed 

 been reported, though not as yet fully proved to occur is 

 one which may be confidently expected as an addition ; and 

 it is also quite within the bounds of possibility that one of the 

 horse-shoe bats, which are considered by good authorities to per- 

 form an annual north and south migration, may yet turn up as a
