Notices and Analyses, 259 



The author has already announced in the Ornis that the females of the 

 bats live together after they are fecundated, and that they inhabit a 

 common hole, into which they will not permit a male to enter. 

 Recent observations have enabled him to verify tl'is fact, which is 

 particularly striking ia the Vespertilio noctula and JBechsteinii. The 

 females remain always together by a dozen or more imtil they have 

 brought forth their young and reared them. M. Brehm has also 

 assured himself that they only produce one at a birth, and that if 

 there should be two, it is an exception to the general rule, as in the 

 human race. He has observed, that the bats sometimes make use of 

 their anterior extremities as hands, and in this respect they differ 

 from birds, which can never lay hold of any object with their wings. 



The species which he describes is named V. rufescens : it has short 

 reniform ears ; rather short hair ; the upper part of the body grayish 

 rust colour, the under part gray rust colour ; the wings, straight ; 

 the tail, exceeding the membrane 2^ lines ; spread of the wings 16^ 

 inches. This species has some analogy with the V. noctuhy and V. 

 ferrugineus, Brehm. The description was taken from a female 

 found in an old tower in Jena.
