First ridge teiminatiug at oi- closely behind tlie canine ; second at 

 or closely behind p' ; third at ]/ ; fourth at front of p* ; fifth at 

 front of m' ; sixth closely behind ra" ; seventh far behind m^ ; 

 eighth to tenth situated near jjalation border. Palate-ridges in 

 E. sahceum and E. dupreanum not examined. 



Head. — Muzzle long, from front of eye to tip of nostrils almost 

 etjual to distance from front of eye to base of ears. Nostrils sepa- 

 rated by a deep groove ; inner margins moderately projecting. 

 Inner margins of lips fringed with short pajnlliie. Median portioa 

 of tongue with oblique rows of rounded papilla?, each papilla with 

 three small, straight, 8harj)ly pointed, backwardly directed horny 

 spines. 



Ears. — Tij) of eai'-conch reaching hinder corner of eye ; outer 

 margin miich more convex than inner, tip broadly rounded off. 

 Autitragal lobe practically wanting. 



Wings. — Chief characters : second digit clawed ; wings from 

 sides of dorsum, rather closer to spine than to Hanks, and from 

 back of first toe. 



First phalanx of first digit twice the length of metacarpal. 

 Second digit subequal to third metacarpal. Third metacarpal 

 between six and seven tenths the length of the forearm, a little 

 longer tlian the fourth metacarpal, which is a little longer than the 

 fifth. First phalanx of third digit equal to two thirds of meta- 

 carpal ; second phalanx subequal in length to metacarpal. First 

 phalanx of fourth digit rather more than half of metacarpal ; 

 second phalanx always somewhat longer than first. First phalanx 

 of fifth digit less than half of metacarpal ; second phalanx subequal 

 in length to first. See wing-indices, infra. 



First digit included in the membrane by the metacarpal and base 

 of first phalanx. Notopatagium acutely triangular. 16-20 long 

 fasciae in the plagiopatagium, viz. 4-G postanconeal, 12-16 pre- 

 anconeal. 



Tall. — Less than half the length of the hind foot ; basal portion 

 connected with intcrfenioral by its dorsal integument, terminal two 

 or two and a half vertebra; freely projecting. 



l>e.vual differentiation. — Adult males of all species have the 

 glandular hairs on the foreneck and sides of the neck brighter 

 coloured tlian females ; females of E. hdvuni and E. sabermn are 

 lighter coloured above and below than males ; females of E. helvwu 

 and E. sahceum (and dupreanum ?) average a trifle larger than males.
