372 ON A NEW SPECIES OF FRUIT-BAT FROM FERNANDO PO, [Mar. 1, 



appear to be referable to S. zenkeri *, the only known species ; 

 and was therefore described as new, as follows : — 



SCOTONYCTERIS BEBFORDT f. 



Scotonycteris hedfordi, Thomas, Abstr. P. Z. S. 1904, No. 4, 

 p. 14, March 8. 



ISfear S. zenkeri, but ears much smaller. 



Size rather less than in S. zenkeri. Fur close, fine and woolly, 

 the hairs of the back about 6 mm. in length. Fleshy part of 

 forearms, wing-membrane bordering flanks and hind limbs, upper 

 side of legs to ankles, and interf emoral membrane (except terminal 

 part near calcar) well clothed with fur ; the centre of the inter- 

 femoral quite buried in thick fur. Below, the fur was less extended, 

 only covering the proximal part of the wing-membrane and the 

 centre of the interfemoral. 



General colour above mixed whitish and ochraceous buff, the 

 hairs dark brown at base, then silvery white, their tips pale 

 brownish bufiy or "clay-colour," the peripheral hairs of membranes 

 and limbs wholly of the latter colour. Head rather browner than 

 back. Central white muzzle-patch present, as in the type sjaecies ; 

 eyes with dark rims, interrupted behind by small white postocular 

 spots, only about 2 mm. in diameter. Owing to the general light 

 colour, these patches are but little prominent. Ears very small 

 and narrow, conspicuously smaller than in S. zenkeri. Throat 

 and centre of chest creamy whitish, passing on shoulders, sides 

 of body, and inguinal region into brown. 



Dimensions of the type : — 



Forearm 48 mm. 



Head and body (original measure in the flesh) 71 ; ear (in 

 flesh) 11; thumb (c. u.) 23; first finger — metacarpal 34, 1st 

 phalanx 24, 2nd phalanx 30 ; fifth finger 63 ; tibia 20 ; calcar 6. 



Hah. Fish Town, Fernando Po. 



Type. Female. Original number 31. Collected 2 January, 

 1904, by E. Seimund. 



This interesting Bat, which had been named in honour of its 

 joint donor, the President of the Society, was the first repre- 

 sentative of the genus Scotonycteris received by the National 

 Museum, and was therefore a most welcome accession. It 

 difiered from ^S'. zenkeri, of the Cameroons, by its conspicuously 

 smaller ears, which were only 11 mm. in length, while those of 

 S. zenkeri were stated by Dr. Matschie to be 17 mm. long, a 

 measurement that quite agreed with then* appearance in his plate. 

 S. hedfordi also seemed to have smaller postocular spots and a 

 more hairy interfemoral membrane than its mainland ally.
