have increased in lengthy making as a total result the fifth 

 and third metacarpal subequal, the fourth the shortest. In 

 (J/i/ji/iojii/clcris the first phahmx of the third digit is 

 shortened, the second corrL'S|)on(liiigly lengtheucd ; in other 

 words, the joint between the two phahmges has Ijeen removed 

 in proximal direction (compare wing-indices of Glypho- 

 nf/cteris and M. me(jalotis). The joiut between the first and 

 second phalanx of the fourth digit has been similarly removed 

 in proximal directioUj making the latter phalanx decidedly 

 longer than the former. 



Species. — The genus was based on G. sylvestris. An 

 examination of the British Museum material has convinced 

 me that Peters^s AI. Behn'i is a Ghjphoi^ycteris ; the same is 

 probably the case with Dobson's M. bracliyotis. 



Range. — From Brazil (Matto Grosso) and Peru through 

 Guiana to Central America.

I860. Schizustoma Dehnii, Peters, MB. Akad. Berlin, pp. oO-j-S. — 

 Type : $ ad., in alcohol ; Ciiyaba, Brazil. 



Skull and teeth. — See the diagnosis of the genus. 



Ears. — Short ; not reaching the tip of the muzzle when 

 laid forwards. Cross-striie faint, rather ill-defined ; number 

 about 10 (?), covering a space of about 9 mm. 



Nose-leaves. — Essentially as in M. rneyalotis, the extreme 

 length of the lancet being equal to about l\ its width at 

 base. 



IVings. — Forearm practically naked. ^Membranes from 

 the ankles. Length of forearm about 45-47 mm. 



Calcar. — Shorter than the foot and very nearly equal to 

 half the length of the lower leg. 



Tail and interfemoral. — The postcaudal interfem )ral seems 

 to be equal to the length of the tail (the available specimens 

 are somewhat damaged) . 



Specimens examined. — River Cosnipata, District of Puno, 

 S.E. Peru (.2, skins in alcohol). One skull. 



Range. — As yet only recorded from Cuyaba (Matto Grosso) 

 and Cosnipata.
