Mazama zetta Tuomas, Ann. and Mag. Nat. Hist. (8), XI, p. 586, June, 1915. 
Type locality, Medellin, Antioquia, Colombia. 
Two specimens, adult female and young in spotted coat, from Gallera, 
Colombia (altitude 5700 feet), “referred provisionally’? by me in 1912 to 
Mazama tschudit, appear to agree quite satisfactorily with Thomas’s de- 
scription of Mazama zetta from Medellin. The female is fully adult, with 
much worn teeth. The fawn in spotted coat is very much darker than the 
adult. 
Field measurements of the adult female: total length, 1180 mm.; tail 
vertebrae, 180. The skull measures, total length, 200; condylobasal length, 
188; occipitonasal length, 173; preorbital length, 101; zygomatic breadth, 
87.5; orbital breadth, 86; interorbital breadth, 40; occipital breadth, 60; 
breadth of braincase, 60; length of nasals, 64; breadth of nasals, 29; maxil- 
lary toothrow, 60; m'%, 27.3. Preorbital length 50% of the condylo- 
basal. ‘ 
Thomas’s measurements “of fully adult male and female skulls,” as 
far as they are comparable with the above, are: Condylobasal length, 187, 
190; interorbital breadth, 42, 46; maxillary toothrow, 60, 61. 
Two other specimens require mention in the present connection, both 
from the eastern slope of the southern end of the Eastern Andes of Colombia. 
Both are fawns in spotted coat, skins without skulls; one is much younger 
and smaller than the other, and it lacks head, neck, and feet. The younger 
one, apparently not more than a few days old when killed, is from La Candela - 
(altitude 6500 feet), and has the ground color very dark and the white 
spots very sharply defined. The older one, still in spotted coat, from La 
Palma (altitude 5300 feet, a few miles east of La Candela), has the ground 
color very much lighter, the white spots less sharply defined, the pelage 
much coarser and longer, and the hairs of the nape not reversed. Compared 
with a fawn from Gallera, southern part of the Colombian Western Andes, 
(referred above provisionally to M. zetta), the coloration is strikingly differ- 
ent, the La Palma specimen being light yellowish rufous on the flanks and 
ventral surface, but the middle of the dorsal area and the top of the head 
are much darker. In the Gallera specimen the top of the head, top of the 
nape, and the dorsal area are dark brown with a faint dark rufous suffusion: 
the flanks are rufous; the fore neck, chest, and belly are much lighter, 
mostly dingy gray suffused with very pale rufous, the tips of the hairs lighter.
