 By Oldfield Thomas. 



Glauconycteris papilio^ sp. n. 



Allied to G. variegatus, Tomes, with which it has liitherto 

 been confounded ; but the acquisition by the British Museum 

 of the co-types of that species in the Tomes collection enables 

 me to clear up the confusion. 



Size smaller than in variegatus (forearm 41 instead of 15). 

 General colour of the ends of the hairs above uniform clay- 

 colour from head to rump, exactly matchin<^ the posterior 

 back of variegatus, but in tiie latter the head and slioulders 

 are whitish, the clay-colour being only present posteriorly. 

 Individually the hairs are pale slaty basally, then silvery 

 cream-colour, the tips being pale brownish clay-colour. Under 

 surface uniform cream-bufFfrom chin to anus, the corresponding 

 part of C. variegatus being white. Wings and interferaoral 

 membrane variegated as in the allied species. Inner basal 

 lobe of ear rounded. 



Skull as in G. variegatus, but shorter, while nearly as 

 broad. Inner upper incisors similarly unicuspid; outer 

 minute. 



Dimensions of the type (measured in skin) : — 



Forearm 41 mm. 



Third finger, metacarpus 40, first phalanx 15, second 

 phalanx 27 ; fifth finger, metacarpus 38, first phalanx \), 

 second phalanx 9 ; lower leg and foot (c. u.) 27.

Mr. Tomes's collection contains six specimens of '* Scoto- 

 philus variegatus," among which two labelled in his hand- 

 writing can be identified as those of which he gave the 

 dimensions in his original description *. Dobson\s state- 

 ment that the type of this species was in the Berlin Museum 

 was therefore erroneous.
