The figure of C. campestris in F. Cuvier, Mamm. Lithog., is evi¬ 
dently a Cariacus, and not of this genus. The horns from Brazils 
figured by Cuvier (Oss. Foss. iv. t. 3. f. 48) appear to belong to quite 
a different species. It may be the variety of the Boebuck, figured 
in Griffith, A. K. iv. t. 164. f. 6. 
14. Cariacus, Gray; Mazama, Sundev.; Mazama, part.H.Smith. 
Horns cylindrical, arched, with a central, internal snag, the tip 
bent forwards, and with the lower branches on the hinder edge ; they 
are covered with soft thin hair, have a moderate tail furnished with 
long hair on the under side, a white anal disk, rather elongated, 
large, rounded ears ; they generally have a tuft of white hair on the 
outer side of the hind-leg, rather below the middle of the metacarpus.
