The head, viewed from above, presents a triangular figure, of which 

 the tip of the muzzle forms the apex, and is somewhat acute ; the 

 nose is slightly prominent ; the nostrils terminal, and but slightly 

 separated ; the upper lip terminates in a point ; the under lip is some- 

 what swollen at the extremity, and a largeish transverse swelling or 

 tubercle is observed below the chin. The ears have the anterior 

 part running on to the forehead, but separated by a space of about 

 two lines, which space is occupied by the deep frontal pit ; they arc 

 of moderate size, perhaps might be called rather large ; the lateral 

 and anterior margins meet so as to form nearly a right angle ; on the 

 anterior margin, which is thickened, is a series of pointed tubercles ; 

 the lateral or outer margin is very slightly emarginated, and on the 

 inner side numerous transverse small folds or ridges are perceptible ; 

 the point of the ear is narrow, but rounded. The tragus is scarcely 

 2 lines in length, and about 2y lines in width, rounded at the apex 

 and contracted at the base. The tail is enclosed in the interfemoral 

 membrane rather less than one-third of its length. The interfemoral 

 membrane is about eleven lines in antero-posterior extent, naked 

 beneath, slightly hairy above to the base of the free portion of the 

 tail, which has a few long scattered hairs. The feet are almost naked, 

 having only a few scattered hairs. The limbs are of a pale dirty flesh - 

 colour. 



The teeth most nearly resemble those of skull fig. 11. pi. 60. of 

 Temminck's Monograph, but the incisors are more expanded at the 

 apex than represented in that figure, and very deeply notched. The 



formulae are the same, viz. incisors, — -; canines, j^-r ; molars, -^^ , 



the first false molar of the upper jaw is small and almost hidden by 

 the gum ; the second distinct ; both first and second false molars of 

 lower jaw are distinct ; the latter is most elevated, but the foremost 

 is the largest. The palate has numerous well-developed transverse 

 ridges, seven in number, if we commence from between the canines, 

 in front of which are two others less distinct ; the third, which is 

 between the false molars, is most developed. The tongue is thick, 

 but pointed at the apex, and presents a triangular transverse section, 

 extending in its ordinary position to the incisor teeth, which on the 

 inner side are covered by the gum up to their points. 



Besides these, and the Philippine Island Bats noticed or described 

 in the 'Annals,' vol. xiii. p. 302, I have to add, as also forming part 

 of Mr. Cuming's collection, a species of Nycticejus which agrees 

 most closely with the N. borbonicus ; this and the Taphozons phi- 

 lippinensis appear to be extremely abundant in the Philippine Islands ; 

 and lastly, a species of Dysopes, which I feel very little doubt is the 

 Z). tenuis of Horsfield ; it agrees most closely with the detailed de- 

 scription and figure given by Temminck.
