The molar teeth in this species appear to be proportionally smaller than in any other known species of Megachiroptera, while the canines are longer and stronger. Length (of an adult S ) : head and body 4"*0; head 1"*4; eye from nose 0"*55 ; ear 0"*6 ; forearm 2"*4 ; thumb 0"*85 ; first finger l"-9; second finger-metacarp. 1"*85, 1st ph. 1"*35, 2nd ph. 1'*9; fourth finger-metacarp. 1''9, 1st. ph. 0"*8, 2nd ph. 0"*8 ; tibia 1"*05; calcaneum 0"*3; foot and claws 0"*7. Suborder MICROCHIROPTERA. Family R H I N O L O P H I D ^ E. PHYLLORHINA TRICUSPIDATA, Rhinolophus tricuspidatus, Temminck, Monogr. Mammal, ii. p pl. 32. figs. 11, 12(1835-41). V ' One specimen of this small species with fur bright reddish brown above and beneath. P. tricuspidata is probably the smallest species of Rhinolophidee, and has hitherto been recorded from the Moluccas and Amboyna only. PHYLLORHINA GALERITA. Hipposideros galeritus, Cantor, Journ. Asiat. Soc. Beng. 1846, p. 183. Phyllorhina labuanensis, Tomes, P. Z. S. 1858, p. 538. Phyllorhina longicauda, Peters, Monatsber. Akad. Berl. 1861 p. 708. Phyllorhina brachyota, Dobson, Journ. Asiat. Soc. Beng 1874 p. 237. Phyllorhina galerita, Dobson, Monogr. Asiat. Chiropt p 69 (1876). The single specimen in the collection agrees with individuals of this species from the Oriental Region in having the tail almost wholly included in the interfemoral membrane, and not with the very closely allied P. cervina from Australia, which has the last and half the antepenultimate caudal vertebra free. It is therefore very doubtful if P. cervina can be considered distinct from this species. As P. galerita is also found in the Peninsula of India and in Burmah, its geographical distribution is very wide, much wider than that of any other known species of Rhinolophidee ; for although P. speoris was described by Zelebor under the name of P. taitiensis we are not absolutely certain that the specimen so named was really obtained at the island Tahiti. |
