15^ Zoological Society ;— 



wing-membranes are said to extend the whole length of the foot, 

 quite to the claws, which they certainly do in the specimen in the 

 British Museum ; but in a specimen in my own collection they do 

 not reach to the claws ; scarcely further than to the middle of the 

 toes *\ This I have been able to ascertain by softening the speci- 

 men ; but one in spirit is required to determine this point with ac- 

 curacy. The feet themselves are rather long, and the toes are two- 

 thirds of their entire length. 



The tail is a little longer in relation to the size of the animal than 

 it is in the species of the group with which I have found it most 

 nearly allied, i. e. the group containing the before-instanced species, 

 V.formosuSy &c. 



All the membranes are somewhat translucent ; those of the wings 

 are rather distinctly veined ; and near to the sides of the body and 

 legs they are marked with dotted lines, as is also conspicuously the 

 case with the interfemoral membrane. The ears are faintly marked 

 with small dots, but not nearly so much so as in Kerivoula. 



The fur of the head extends uninterruptedly to near the end of the 

 nose, in precisely the same manner as it does in V. emarginatus ; and 

 there is a similar naked space around the eye. All the upper sur- 

 face of the interfemoral membrane is hairy, as is also the upjier surface 

 of the wing-membranes near to the body ; but everywhere else the 

 membranes are naked. On the back the fur is tricoloured ; on the 

 under parts it is bicoloured. 



In general form the cranium very much resembles that of V. 

 emarginatus ; and in form and relative proportion the teeth are also 

 similar, but differ in numbering one more premolar in the upper jaw, 

 and one less in the lower. Their number may be thus stated : 



luc. 2=?; Can. jEl; Prem. g; Mol. S=l-». 



Those of the upper jaw are arranged in two straight lines, which are 

 nearly parallel ; and across the front opening of these the incisors 

 are placed in pairs, of nearly uniform size, close together, with a very 

 moderate interval on each side between them and the canines, and a 

 moderate central opening. They are simple in form, with their cutting 

 edges somewhat flattened. The canines are short and stout, somewhat 

 conical, without accessory cusp or point, and with a feebly developed 

 cingulum inside the tooth. Following these are two premolars, short 

 and stout, and somewhat pyramidal in form, without internal lobe 

 or projection. The following two molars are of the form so common 

 in all the Vesper tilionid(B ; but they, like all the other teeth, have 

 their cusps less acute than is usual, and the inner ones rather less 

 extended towards the central part of the palate. The last molar is 

 of small size, and transverse in form. 



In the lower jaw the teeth are, as may be inferred from those in 

 the upper, arranged in two straight lines, a little narrower in front 

 than behind. The incisors are of the ordinary form, and trilobed ; 



* This specimen is one I purchased with other Indian mammals, which formed 

 part of the collection made by Capt. Boys.
