2. PTER0PU8. 29 



7. Pteropus aneiteanus. 



Spectrum anetianum, Grmi, Catal. Monkeys and Fruit-eating Bats, 

 p. 101 (1870). 



Muzzle much shorter than in Pt. dasymallus ; ears slightly shorter 

 than the muzzle ; the ear-conch almost naked, but more than half 

 concealed by the long fur of the neck and side of the head, inner 

 and outer margins equally slanting inwards above to form the 

 narrowly rounded tip. Interfemoral membrane scarcely developed 

 in the centre, quite concealed by the long woolly fur. 



Face, head, chin, and throat dark brown, the extremities of the 

 hairs pale brown or shining ; back of the head, nape, and collar 

 bright reddish brown ; shoulders and anterior part of the back pale 

 yellow ; back reddish brown, with paler extremities, becoming yel- 

 lowish brown posteriorly ; chest and abdomen dark brown, sides of 

 the body reddish brown. 



Pur, above long and woolly ; on the back nearly as long as that 

 on the neck and shoidders, and not appressed, extending outwards 

 thickly upon the humerus and forearm, and, posteriorly, upon the 

 legs to the ankles, but leaving the feet naked, and densely clothing 

 the short interfemoral membrane ; beneath the tibiae are nearly naked. 

 Facial bones much shorter than in Pt. dasymallus (see Table, 

 p. 30), although the distance from the occipital crest to the supra- 

 orbital foramen is the same in both species ; upper incisors nearly 

 equal ; lower outer incisors more than double the size of the inner 

 incisors, which are not separated by a space in the centre ; first 

 upper premolar as large as one of the inner lower incisors, persistent, 

 nearly filling up the space between the canine and second premolar 

 by its base ; second upper premolar and thii-d lower premolar with 

 a small antero-intemal basal cusp, as in Pt. juhatus ; premolars and 

 molars (except first premolar and last molar) acutely tubercular (vide 

 Plate IV. fig. 2), more so than in any other species of the genus, each 

 tooth with prominent external and internal cusps and a well-defined 

 cingulum, forming a small antero-internal basal cusp in front, a raised 

 ridge on the inner side of the tooth, and a transverse ridge behind ; 

 last upper molar not larger than one of the outer lower incisors, and 

 scarcely more than half the size of the first lower premolar, which 

 quite fills up the space between the canine and second premolar ; 

 last lower molar very small and circular, scarcely larger than one of 

 the middle lower incisors. 



Length, head 2"-3, ear 0"-8, eye from tip of nostril 0"-8, forearm 

 4"-5, thumb 2", first finger 3"-4; second finger — metacarp. 3"-l, 

 1st ph. 2"-4, 2nd ph. 3"-6 ; fourth finger — metacarp. 3"-3, 1st ph. 

 l"-6, 2nd ph. l"-65 ; tibia 2"-2, calcaneum 0"-4, foot l"-5. 

 Hah. New Hebrides (Aneiteum Island). 



This species is at once distinguished by the very peculiar character 

 of its teeth, of which the premolars and molars are more acutely 

 tubercular than in any other species of the genus. 



In the following Table the measurements of the skull of Pi. 

 aneiteanus are compared with those of Pt. dasymallus and Pt. pse- 

 laphon : —
