86 PIEROPODID^. 



forearm 2"'2, third finger 4", fifth finger 3", thumb 0"-9, tibia 0"-8, 

 foot 0"-5. 



Hah. Southern Andaman Islands. 



Type in the collection of the Indian Museum, Calcutta. 



5. Cynopterus latidens. 



Ears small, oval, roiinded ofE above, naked, not margined with 

 ■white ; muzzle rather short and obtuse. 



Tail very short, quite concealed by the long fur surrounding it. 



Fur of the head in front of and above the eyes very dark brown, 

 almost black ; crown of the head behind the eyes dark brown ; back 

 and neck reddish brown, the greater part of the hairs to the base 

 greyish ; beneath, greyish brown throughout. 



The fur of the body is moderately long and very dense, extending 

 outwards upon the humerus, which it covers altogether, and passes 

 round the elbow to the fleshy part of the forearm ; also upon the 

 wing-membrane as far as a line drawn from the elbow to the knee, 

 and upon the legs and adjoining membranes as far as the metatarsus, 

 the hairs being rather long and moderately dense ; interfemoral mem- 

 brane very short in the centre, and thickly covered above and be- 

 neath with close fur, which conceals its posterior margin and the 

 very short tail. 



The teeth differ remarkably from those of every other known 

 species of CytiojHerus in their large size and great width (Plate V. 

 fig. 1). The transverse and longitudinal diameters of each molar 

 tooth are nearly equal ; the first upper true molar has a very 

 large external cusp ; the last lower molar is very small, with a 

 circular crown, equal to the first lower premolar in cross section, 

 but scarcely one third the diameter of the antepenultimate molar ; 

 the lower canines are close together, their projecting cingulums 

 being separated posteriorly by a narrow space. Some of the lower 

 incisors are evidently deciduous, for in the specimen (the only 

 example of this species as yet obtained) from which this descrip- 

 tion is taken three incisors occupy the whole sjiace between the 

 canines. 



Length, ear 0"-6, forearm 2"-8, thumb 1" ; third finger — meta- 

 carp. 2", 1st ph. l"-5, 2nd ph. l"-9 ; fifth finger — metaoarp. l"-9, 

 1st ph. 0"-9, 2nd ph. 0"-9 ; foot 0"-65. 



Hah. Morty Island, Malay Archipelago. 



This species is at once distinguished by the very peculiar form of 

 the molar teeth, which are not only difEerent from those of every 

 known species of Cynopterus, but also from those of every species of 

 the suborder. Molar teeth of a somewhat similar form occur only 

 in certain species of the group Stenodermata (of the widely sepa- 

 rated family PhyUostomidae), which are also frugivorous in their 

 habits.
