its woolly fur, pale red on the back and extending markedly on the 

 interfemoral membrane, by its ears being very much eniarginated, its 

 thick muzzle, &c. The colour of the emarginatus is nearly that of 

 the Serotinus." At page 300 of the same work are some additions, 

 among which the following occurs : — " Relatively to the Vesp. emar- 

 ginatus, MM. Key selling and Blasius have fallen into three remarkable 

 errors : 1st, they consider that of Jenyns to be V. Daubentonii ; 2nd, 

 that of Geoffroy to be V. mystacinus ; 3rd, they think that of Tem- 

 minck is a copy, a little altered, of the figure given by Geoffroy, &c. 

 I have proof that these assertions are incorrect. The emarginatus is 

 as distinct from our other Vespertiliones as the Arvicola subterraneus 

 is from our other Campagnols." At the end of the work a plate is 

 given of the ears and feet of several European species of bats, amongst 

 which are V. Nattered, V. mystacinus and V. emarginatus ; and un- 

 less the figures are exceedingly incorrect, the latter species must differ 

 materially from the other two, but certainly bears the greatest resem- 

 blance to the first of these in the form of the ear, with the lobe folded 

 inwards, as in that figure. But the author is evidently incorrect in 

 some of these remarks, and MM. Keyserling and Blasius are right; 

 for instance, the V. emarginatus of Jenyns is admitted by that gen- 

 tleman himself to be referrible to some other species, probably V. 

 Daubentonii; and again, a very slight inspection of Temminck's 

 figure with that of Geoffroy will convince any one that the former is 

 copied from the latter. 



In 1848, having met with two specimens of bats that I was unable 

 to refer to any of the known British species, except it were the 

 description of the present one as described by Prof. Bell, I examined 

 the account given by the first describer, and also that by Prof. 

 Macgillivray already all tided to, and gave a short notice to the Zoolo- 

 gical Society, which was published in the e Proceedings ' of that year, 

 and again in the ' Annals and Magazine of Natural History ' for 

 August, the following year. 



The next reference to this species that I met with is by Mr. Cocks, 

 in the November number of the ' Naturalist' for 1851, accompanied 

 by a short description and a figure of the head and ears, which, I 

 may remark, differs from every other figure 1 have seen. Then comes 

 the notice by Mr. Couch in the * Zoologist;' and, finally, some ob- 

 servations by G. B. Bucton, Esq., F.L.S., to the Linnean Society, in 

 December, 1853. In the latter paper the author treats the species as 

 a variety of V. Daubentonii, and from his description the specimens
