 NOTES AND QUERIES 



Zoological Maps.— In Mr. Miller Christy's very useful and suggestive 

 paper on Zoological Maps in the last number of ■ The Zoologist ' (pp. 401-8), 

 he proposes that those for Birds should have the lines of migration indicated 

 by arrows. I wonder if he is aware that in the ' Birds of Devon ' such 

 maps have been actually published by Mr. D'Urban and myself, in which 

 the spring and autumn movements of birds to and from the British Islands 

 (more especially as they relate to Devonshire) are attempted to be in this 

 way illustrated? — Murray A. Mathew (Buckland Dinham, Frome). 



MAMMALIA. 



European Beavers at the Zoological Gardens.— Specimens of the 

 American Beaver have long been familiar to visitors in the Regent's Park 

 Zoological Gardens ; but in Europe this animal has become so rare, or at 

 least so restricted in its haunts, that the capture of one, still less the sight 

 of one in London, was scarcely to be hoped for. The acquisition therefore of 

 an entire family, male, female, and four young, from the Lower Rhone, 

 and their successful transport to London, is a very remarkable event, and 

 one which should attract many a curious naturalist to the Zoological 

 Gardens. As to whether the American and European species of Beaver 

 are identical or not, opinions differ; but it is now generally considered that 

 the difference in the shape and length of the nasal bones is sufficient to 

 justify their specific separation. Vide anted, p. 314. — Ed. 



Albino Squirrel. — In * The Zoologist ' for November (p. 426), I reported 

 the occurrence of an albino Squirrel, which was shot at Westonbirt, near 

 Tetbury, on Sept. 11th. Strange to say, another was killed in the same 

 wood about a fortnight later, namely, on October 2nd, and was sent to me 

 for preservation. It proved to be a female, and, like the male previously 

 obtained, was a pure albino. — H. W. Marsden (Bath). 



[It is a pity that they could not have been both taken alive, instead of 

 being shot, for it would have been interesting to have paired them in a 

 good roomy cage with a tree in it, aud have waited to ascertain whether 

 their progeny, if any, would be also white. Possibly they may have been 

 of the same litter. — Ed.] 



Natterer's Bat in South Lancashire. — Mr. Joseph Chappell has iu 

 his collection an example of this species, which was captured in a foundry 

 at Cheetham Hill, Manchester, last Christmas time. The size, pointed 

 tragus, and lash of hairs at the margin of the interfemoral membrane are 

 perhaps sufficient to establish the identification of the species. — Chas. 

 Oldham (Ashton-on-Mersey).
