It is evident that the skull also of C. riparius when it is directly compared with the 
skull of the type of C. variegatus is only distinguishable from it by characters which 
are explicable by the difference of its sex. Measurements of this skull are given in 
the foregoing table. 
In the Berlin Museum there is the skull of a jackal from Somaliland which 
Mr. Matschie informs me may be regarded as a co-type of C. hagenbecki, as it was one 
of Menges’s specimens from the same locality as that which yielded C. hagenbecki and 
was obtained at the same time as the latter. The skull is that of a female and has a 
long pointed muzzle, resembling that of C. riparius, but even more pointed. In view, 
however, of the similarity of the pelage of jackals referable to C. hagenbecki to the 
pelage of jackals conforming to the external characters of C. variegatus, one does not 
seem justified in separating them. The measurements of this co-type are given above.
