the legs to the backs of the feet, even to the base of the claws, and 

 upon the humerus and the muscular part of the forearm ; beneath, 

 long hairs cover the wing-membrane between the anterior and pos- 

 terior extremities, and the legs almost as far as the ankles. 



Upper incisors strong, close together ; lower outer incisors double 

 the size of the inner pair, inner incisors close together ; canines sepa- 

 rated by a rather narrow space from the second premolar, which, 

 with the third premolar, has a posterior and external basal projec- 

 tion ; the first upper premolar minute, deciduous ; last molar slightly 

 larger than the first lower premolar, which fiUs up the space between 

 the canine and second premolar ; the second and third lower pre- 

 molars have external and posterior basal cusps ; last molar about the 

 size of the first premolar. 



Skull remarkably broad across zygomatic arches ; muzzle short ; a 

 process from the zygoma to meet the postorbital process of the frontal. 



Ft. dasymallus has a longer and narrower skuU, and the last upper 

 molar is nearly double the size of the first lower premolar. 



Length, head and body 8"-5, eye from tip of nostril 1", ear 0"-8, 

 forearm 5", thumb 2"-3, third finger 10", fifth finger 6"-5, tibia 

 2"-3, foot l"-8.

 (1870). 



Ears shorter than the muzzle, narrow, and subacutely pointed, 

 clothed with a few short hairs on both sides, nearly concealed by the 

 long fur, which is directed backwards. 



In a young male (type of Ft. ornatus) the fur is bright ferruginous 

 brown above and beneath ; face bufi' ; head ferruginous brown, many 

 of the hairs have their terminal half shining grey ; back of neck and 

 shoulders pale buff, almost white ; some of the hairs of the back 

 greyish as on the head. 



In a female (type of the species) the face is brown, much mixed 

 with grey hairs, so that the prevailing colour is greyish ; a white 

 streak, not weU-defined in every specimen, extends on each side 

 above the eye, separated by a darker-coloured patch between on the 

 forehead ; top and back of the head pale brownish buff, the long fur 

 nearly concealing the ears ; nape pale bufl^, the greater part of the 

 hairs almost white ; back yellowish brown, with a streak of lighter- 

 coloured fur passing down the centre, varying much in breadth in 

 different individuals, in young specimens not discernible ; chest and 

 abdomen bright yellowish brown.
