Genera JMicruiiyctcri.s (ind Glyplioiiyctcris. 57 



Tail Olid inlei'femoral. — The postcaudul poitioii oi the 

 iiiterlVMuoral is shorter than the tail. 



('u/oiir. — ^Al)ove as in 31. lucf/u/utis, below eoiisideralily 

 li;j;hter. I pixTside Front's brown, base of hairs white; 

 nndcrsiile whiti.sh or greyish white in the middle, dralj on 

 the Hanks. 



liani/e. — Brazil, from Santa Catherina in the south to 

 Vara in the north. Extending to Colombia, if M. hypoleuca 

 is identieal with M, miiiuta. 



Sjjcciiueits examined. — 11, from: — Santa Catherina (3); 

 Para (1) ; "Brazil" [4). 



Remarks. — On hasty inspection M. mlnula bears no small 

 resemblance to M. meyalotis. The two species are practically 

 alike in the slia|)e of the skull, in the ears and nose-leaves, 

 and in the general size ; M. miriuta is not, as its technical 

 name might suggest, snuiller than M. megalutls. But 

 M. minuta differs in the following important respects : — 

 In the very conspicuous reduction of pi and j? ; in bavins; 

 the transverse band between the ears divided into two separate 

 triangular lobes ; in having the proximal half of the forearm 

 densely haired; in the proportionately shorter hand; in the 

 larger foot, short calcar, sliort postoaudal interfemoral, and 

 ligliter-coloured underside of the body. 



4. Micronycteris hirsuta, Ptrs. 



18G9. Schizodoma hirsutum, Peters, MB. Akad. Berlin, p. 397. — Type : 

 cJ ad., in alcuhol ; locality iinkuown ; Paris Mutieum. 



Skull. — Similar in shape to the skull of M. megalotis and 

 M. minuta, but much larger, and brain-case less vaulted and 

 raised above the facial region, the profile-line, from the 

 uppermost point of the brain-case to the nasals, therefore 

 less concave. 



Teeth. — Cutting-blade of i^ markedly less compressed 

 antero-posteriorly than in M. megalotis and minuta. Upper 

 premolars as in M. meyalotis. Almost the same is the case 

 with the lower premolars : po slightly higher than y;^, which 

 is slightly higher than p... 



Ears. — Proportionate size as in M. meyalotis and minuta ; 

 number of cross-ridges 13-14, covering a space of about 

 11 mm. 



Transverse band between ears, in both sexes^ very low, 

 straight (not higher in the middle), and without median 

 notch. There seems to be no frontal groove (the two 

 specimens examined of this very rare bat are in a Ijad state 

 of preservation) .
