all the finfiircs clearly apply to a //. (/ii/d^. Tliis speoiineii, 

 the male, stated to have been obtained in I bo Island, Cap 

 l)eI«;ado frroup, theiefore is to be regarded as the type of 

 vitfato, whieli consecpiently' becomes a synonym of Wa^^ner's 

 gigas. The other specimen referred to by Peters (a female, 

 measured on pp. 35-3(3) is^a //. C. marungensis. — Peters's 

 reasons for regarding his vittuta distinct from Wagner's 

 gigas are given by himself as f(dlo\vs (p. 3(5) : — (1) the latter 

 is " russbraun," vittdta '' rehbrann " ; a more or less russet 

 suffusion is, however, an individual, not a specific diirercneo: 

 (2) gigns has, according to Wagner, " nur drei Falten zu 

 jeder Seitc des Hufeiscns," whereas Peters found four in his 

 vittata; but specimens of gigas from the type locality 

 (Benguela) examined by me have four leaflets, and Wagner's 

 statement to the contrary is, as already mentioned, in all 

 probability wrong, or, if correct, based on an individual 

 aberration : (3) gigas was by Peters believed to differ " durcli 

 den ]Mangel (oder die Kleinheit V) der Stirni'iffnung " ; it is 

 true thac Wagner neither in 1845 nor in 1818 mentions the 

 frontal sac in the type of gigas; but in 1855 (Sehreber's 

 * Sjiugthiere'), three years later than Peters's ' Keise nach 

 !Mossambi(iue,' he coriects this omission : (1) gigas differs 

 " durch die nicht bis zur Ferse herabreiehenden Flughaute,'' 

 whereas in vittata " die Flughiiute gelien bis auf die Fuss- 

 wurzel herab'^; this is a purely individual variation {cf. 

 antea, p. 40, footnote *) — Thus, none of the distinguishing 

 characters of vittata emphasized by Peters holds good. 

 Another thing is that by actual comparison of the type of 

 vittata (obtained in Ibo Island) with specimens oi gigas from 

 IJengnela some slight difl'ereuce on othei' pcunts might be 

 found ; but Peters's description of the former is so detailed, 

 and the figures, both of the external aspect and of the 

 skull and dentition, so completely like H. gigas, that the 

 difference, if any there be, must be exceedingly small 

 indeed.
