1915.] Allen, American Deer of the Genus Mazama. 545 
The two fawns, respectively from Gallers and La Palma, unquestionably 
represent different species, but the material is too unsatisfactory for positive 
identification. It is possible that the La Palma specimen may be referable 
to M. sheila, from the lowlands near Merida, as the coloration and unre- 
versed nape hairs suggest that type. ; 
Mazama gualea sp. nov. 
Type No. 36473, @ adult, Gualea (altitude 6000 feet), Ecuador, June 2, 1913; 
W. B. Richardson. 
Size large; coloration dark; hair of back of neck reversed. Upperparts near 
liver brown of Ridgway, darker over the middle region of the back, lighter and more 
tinged with rufous on the sides and underparts; back of neck and head (including 
ears) not darker than the middle of the back; a lighter band, tinged with rufous, 
over the eyes; the usual white patch on the lip bordering the rhinarium; chin whitish, 
bordered posteriorly with a broad band of dark brown, broken by whitish on the 
median line; throat dingy grayish white; foreneck drab gray; inguinal region and 
inside of thighs clear white, from which a white band descends on the inside of the 
hind limb nearly to the hock; limbs otherwise dark brown, like the upperparts; 
tail above like the back, white below; ears dark brown externally, whitish near inner 
base, and fringed with white internally. ; 
Represented by the type from Gualea and another female from Mount Pichincha. 
In coloration the two specimens are essentially alike. 
Collector’s measurements: Total length (female, type), 1050 mm.; tail vertebre, 
50; hind foot, 290. Female, Mount Pichincha, total length, 1250; tail vertebre, 60; 
hind foot, 290. : 
Skull (female, type, Gualea; young female, nearly adult, Mount Pichincha); 
total length, 195, 193; condylobasal length, 185, 179; occipitonasal length, 165, 163; ° 
preorbital length, 96.5, 96.5; zygomatic breadth, 86.5, 88; orbital breadth, 88, 84; 
interorbital breadth, 45, 45; occipital breadth, 65, 59; breadth of braincase, 60, 57.95; 
length of nasals, 56, 55; breadth of nasals, 27, 26.5; maxillary toothrow, 58, 63; 
m!-3, 27, 29. The ratio of preorbital length to the condylobasal is, respectively, 
52.3%, and 538.3%. 
This form seems nearest related to M. zetta of Antioqua, but greatly 
exceeds the type in size, and is very much darker and much less rufous. 
Mazama fuscata sp. nov. 
Type, No. 34267, @ ad., Rio de Oro, Manavi, Ecuador; altitude, near sea-level. 
Size large; coloration blackish brown; hair on back of neck reversed. Similar 
to M. gualea but coloration much darker and size larger. Upperparts blackish brown 
darker, almost black, over the whole dorsal area, browner on the sides where the 
hairs are finely vermiculated with rufous near the tips; belly nearly drab brown, but 
little lighter than the flanks, with a faint rufous suffusion; inguinal region clear white,
