juice ol' wiiicli it .sucks, carefully rejecting the fibrous parts ; hut 

 since a certain portion of the latter must necessarily enter the 

 mouth while the animal is feeding, this is rolled up in the hollow 

 of the palate, and when the juices are abstracted it is removed 

 from its lodgement by an oblique application of the tongue to make 

 room for the next juicy morsel of parenchym.'" Considering the 

 unusually heavy dentition of this species, its large temporal muscles, 

 ami correspondingly strong sagittal crest and coronoid process, it 

 appears probable that the cheek-teeth act as powerful grinders 

 to squeeze the juice and soft flesh from the tough fibrous parts of 

 Ihe fruits ; otherwise it would be difRcnlt to reconcile Lay's 

 statement, that this bat " sucks " the juice of the fruits, with the 

 actual characters of its teeth and skull. 



History in literature. — First described in 1829, by Tradcseant 

 Lay, on the basis of specimens obtained in the Bonin Islands 

 iluring the Voyage of H.M.S. ' Blossom ' (Capt. Beechey). The 

 ])late given by Sir J. llichard.sou (Zool. Beechey, pi. ii.) is far from 

 giving a correct idea of the colour of the fur (the seal-brown 

 in this species soon fades to paler brown by exposure to light). 

 'i'emminck's description was based on a specimen collected in the 

 Bouins by Kittlitz ; the single skull now in the collection of the 

 Leyden Museum is not (as said by Jentink, I. s. c.) the original of 

 Temminck's figures, Mon. Mamm. ii. pL xxxvi. figs. 9-11. By 

 Gray this species was catalogued under the name Pselaphon nrsimts, 

 evidently without the author having any intention to make it the 

 type of a new genus, " Fsela2>hon " being no doubt simply a slip of 

 the pen for Ptirojms. 



Pteropiis ursiynis, Temm. ; 1837. — A manuscript name suggested 

 by Kittlitz and first made known by Temminck, as an alternative 

 name for '■' jiselaphon,'' which he considered " pen approprie."'
