568 CASINrCTERIS. 



the only incompletely concealed white colour of the middle of the 

 hairs. Head and nape similar to baok, though with a deeper 

 russet colour to the tips of the hairs ; a sharply defined white patch 

 of oblong shape on the bridge of the rostrum, extending back 

 nearly to level of middle of eyes ; a small white patch immediately 

 behind posterior canthus of eye ; upper lip narrowly edged with 

 white from angle of mouth to some distance from nostrils. Fore- 

 neck and centre of breast gre5'ish white, shading to hair-brown 

 sprinkled with white on sides of breast ; flanks light wood-brown. 

 Ears and wing-membranes in dried state brownish (in the live 

 animal perhaps bright-coloured : compare Casinycteris, p. 572). 



Measurements. On pp. 573-575. 



Specimens examined. The type of the species (Berlin ]\Jusenm), 

 the type of S. bcdfonli, and an immature maio from Elephajit Lake, 

 N.W. Cameroons (Berlin Museum), these thi-ee being apparently 

 the only specimens on record. 



Itan(je. As yet known only from the Cameroons (Yaunde and 

 Elephant Lake) and the island of Fernando Po. 



Ti/pe, an adult female, preserved in alcohol, skull extracted, 

 Yaunde, S. Cameroons, collected by G. Zenker, Berlin Museum, 

 unnumbered. For measurements see pp. 573-575. 



/S'. bedfordi, Thomas; 190-1. — Type from Fernando Po, in 

 collection. According to Matschie (Z. e. 1S94) the ear of the tj-pe 

 of S. zenkeri measures 17 mm. ; Thomas found the ear of an adult 

 Fernando Po specimen of the same sex measuring only 11 mm., 

 hence very naturally believed it an insular species distinct from the 

 continental S. zenkeri, and named it S. bedfordi. In reality 

 Matschie's statement is erroneous ; the type of zenkeri is in the size 

 of the ears (12"5 mm.) as in all other characters indistinguishable 

 from the type of bedfordi. Measurements on pp. 573-575.

Type. 

 iniO. CasinycterLs, Thomas, An?i. ^' Mat/. N. II. (8) vi. 



p. 1 11 (1 July) C. argyunis. 



Diacjnosis. — Closely allied to Scotovycteris, but postdental palate 

 quite obsolete, posterior nares nearly at level of back of ujjper 

 molar, inner cusp of p^ and p^ well developed and separate from 

 outer. External characters (even colour of fur, including peculiar 

 markings of head) as in Scotonycteris, except for larger size of ears 

 and presence of the usual Epomophorine white hair-tuft at base 

 of ears anteriorlj'. Size of single species known, somewhat larger 

 than Scotonycteris zevkeri. [Hab. Cameroons.] 



Skull (fig. 43). — nostrum distinctly shorter than in Scotonycteris 

 (orbit to tip of nas^als equal to, in Scofonj/cieris more than, one-fourth 

 of total length of skull, lambda to gnathion), somewhat broader, with 

 int^rof'Ular region more deeply eonca-fe, profile lifie from lachrymal
