A few preliminary remarks on the chief features of the following 

 report will not be without, interest. 



The Mammalia of Yorkshire were for the most part so well known 

 at the time of publication of the Handbook, that but little is required 

 by way of addition or correction, except so far as regards the two 

 groups— the Bats and the Cetaceans — which appear to be always the 

 most imperfectly studied mammals in any district. 



With regard to the Bats, the result of Roebuck's investigations has 

 been that, with the assistance of correspondents, the geographical 

 range of some of the forms in Yorkshire has been studied to some 

 purpose. One species is added to the list, and two others — hitherto 

 only recorded for the county on the strength of isolated occurrences — 

 have been fully confirmed as inhabiting the county, one of the latter 

 indeed proving to be a common and widely distributed form. There 

 is yet good work to be done in this group, for Danbenton's Bat — 

 which is sure to be found sooner or later — has not yet been detected. 

 Yorkshire appears still to remain the northern limit of the range of 

 the Noctule, as Mr. R. Morton Middleton informs us that its reported 

 occurrence in South Durham was not confirmed. 



The study of the Cetaceans is much more difiicult from their habitat 

 and large size, and our only hope is that a competent naturalist may 

 be at hand in the event of the capture of animals of this order.
