Booth : Yorkshire Bats, 363 



and that record has been looked upon by some as suspicious. 

 The last record before that was in 1886 ; only four years after 

 the publication of its occurrence in the county [The Zoologist, 

 1882, p. 186), although the record was made from two speci- 

 mens collected in 1876. After exhaustive inquiries, and a 

 thorough search, we concluded that the species was now 

 extinct in Yorkshire (see The Naturalist, 1915, p. 207). It 

 is needless to say what pleasure and delight I, as the writer 

 of that report, felt on being present at the capture of a living 

 Lesser Horse-shoe Bat in an entirely different district, and 

 equally as far north in Yorkshire ! It proved to be a female, 

 heavy in young. Mr. Gordon has tried to secure another one, 

 but so far without success. 



The Reddish-grey Bat {Myotis nattereri) at Helmsley. — 

 On June 5th, Mr. A. Gordon and I investigated a pot-hole on 

 a hillside of the Deer Park in Duncombe Park. We saw two 

 or three small bats of a lightish colour, but were unable to 

 secure any. Later, Mr. Gordon captured one, and it proved 

 to be a female Reddish -grey or Natterer's Bat. He has since 

 taken two males of this species at the ruin where the Barbas- 

 telle's are, one of which I have seen. 



A Correction. — In my note on the bats of Duncombe 

 Park {The Naturalist, 1920, p. 380), I included the Whiskered 

 Bat among the five species that Mr. Gordon had then taken 

 there. He had only one specimen of this bat, which I have 

 since seen, and Mr. Gordon now agrees with me that it is 

 Daubenton's Bat. Its face contains more hair than is usual 

 with that species — hence the error in its identification. The 

 Whiskered Bat, therefore, must be eliminated from Mr. 

 Gordon's list of bats for Duncombe Park. It is a splendid 

 list for Yorkshire, and is the only district that can equal the 

 Barnsley district with its seven species. Duncombe Park, 

 with its ruins, old trees, river, etc., is an ideal place for bats, 

 and, no doubt, one, or perhaps both, the two other species 

 on the Yorkshire list will eventually be found there. As 

 an illustration, I may state that during a very favourable 

 evening this summer, Mr. Gordon netted nine Barbastelles, 

 thirteen Pipistrelles, two Natterer's, and five Long-eared 

 Bats ! These nine Barbastelles and two Natterer's bats I 

 have mentioned before, and of the whole ' catch,' all but three 

 were liberated. 



P.S. — Since writing the above I have received the loan of 

 an adult male Barbastelle from Mr. Gordon, which is set up 

 in the same way as the young male, viz., in a crawling position. 

 The photograph (for which i am indebted to Mr. W. J. Forrest) 

 shows them about three-fourths natural size, and gives a fair 

 idea of comparison in size and bulk between the young and 

 old maic.
