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 asa
