but the canines are very short and rather stout, and are furnished 

 with an obtuse lobe on their inner surfaces sufficiently prominent to 

 occupy a space equal in breadth to the two outer incisors on each 

 side, behind and above which it may be seen when looking at the 

 jaw in front. The same peculiarity occurs, but in a less degree, in 

 the canines of the common Noctule Bat. The two next teeth are 

 triangularly pyramidal in form, short and blunt, with faint indica- 

 tions of inner accessory cusps. Following these are the three true 

 molars, requiring only to be noticed as having their cusps less acute 

 than is usual.

On all the upper parts, with the exception of the interfemoral 

 membrane, the fur is tricoloured, brown at the base, succeeded by 

 pale rufous, and with the ends of the hairs of a brighter and deeper 

 tint of the same colour ; and in the specimen in the British Museum 

 the extreme tips are a little paler, giving an indication of a fourth 

 colour. The hair on the interfemoral membrane is of a uniform 

 light brownish-rufous colour. Beneath it is bicoloured, dark brown 

 at the base, with its terminal third brownish cream- colour, but 

 rufous on the humeral region. The specimen in the British Museum 

 (included in Dr. Gray's Catalogue) has the fur much more distinctly 

 marked with the different tints than the one in my own collection, 

 in which they are very faint. The specimen in the Museum of the 

 Hon. East India Company, collected by Mr. Hodgson in Nepal, and 

 forwarded with the name of Noctulinia lasyura attached, has the 

 colours well-marked. This, with the one in the National Collection, 

 is decidedly smaller than the one in my own collection. M. Tem- 

 minck's specimen would seem to be smaller than either ; but I can- 

 not find any other disparity, excepting that of size, sufficiently 

 marked to establish the existence of a second species. Probably the 

 smaller island example, from which M. Temminck took his descrip- 

 tion, may hold the same relation to those from the continent of India, 

 which the smaller specimen of V. Pearsonii from Amboyna does to 

 those collected by Dr. Pearson at Darjeeling, of which I have spoken 

 in a previous communication.

 of the specimen in the British Museum ; those of No. 2 are from the 

 one in my own collection (collected by Capt. Boys) ; No. 3 from M.
