having a decided greyish tinge, and of somewhat greater 

 size than usual. Specimens, on the contrary, from the 

 Asiatic foot of the Ural Mountains, arc without the least 

 appearance of grey or brown, all the upper parts being 

 of a uniform yellowish cream colour, the fur very long 

 and silky. The under parts of this beautiful variety are 

 of a tarnished yellowish white colour. From India, and 

 from the Island of Amoy, specimens of a Bat have been 

 received which differs only from the Serotine, in all 

 external characters, in having the fur of a dark brown, 

 tipped on the upper parts with whitish brown, and 

 giving the animal somewhat the appearance of the Scoto- 

 philus discolor. M. Temminck's examples of Vespertilio 

 megalurus differ only from ordinary young individuals 

 of the Serotine in having all the fur paler, that which is 

 on the membi'anes being cream-coloured. 



In yovmg individuals the head is more round and 

 thick in proportion, the muzzle shorter and more 

 obtuse, the lip very tumid, and the colours more obscure, 

 than in the adult.
