limbs like the flanks with a tone of grayish drab, the white of the underparts con- 
tinued as a narrowing white band as far as the hock; tail above like the back, beneath 
white; top of head wood brown, sides of head pale drab gray, passing gradually into 
the white of the throat; usually a small white or whitish spot over the anterior 
corner of the eye, often absent (or only a trace, as in the type); rest of the space 
between the orbital region and the long hair of the crown reddish ochraceous i 
a conspicuous white lip spot on each side of the nose; ears clothed externally with 
very short wood brown hair, bordered with white, especially basally. 
Collector’s measurements: ‘Length 3 feet 8 inches [1117 mm.]; girth, 2 feet 13 
inches [654 mm.]” Skull (type), total length, 183 mm.; condylobasal length, 181: 
occipitonasal length, 165; preorbital length, 93.5; zygomatic breadth, 79; interorbi- 
tal breadth, 45; orbital breadth, 81; breadth of braincase, 54 ; occipital breadth, 79: 
nasals, 52 X 27.5; maxillary toothrow, 59 (maximum in a series of 12 skulls); antlers, 
length from burr 104, diameter at burr 15, length of pedicel, 8. (See next page for 
table of measurements.) 
The variation in color is not very great and appears to be correlated 
largely with season; March and April specimens are more ochraceous than 
November and December examples, and the pelage is fuller and longer, and 
the hairs of the crown more strongly tipped with rufous. The white eyespot 
is present in most of the specimens, in some large and conspicuous, in others 
reduced to a mere trace or wholly wanting. The young in spotted coat are 
yellowish ochraceous above with the white spots rather dull and not sharply 
defined. 
Mazama cita sanctemarte belongs to the M. nemorwaga group, but 
differs from typical nemorivaga in larger size and more fulvous coloration. 
It is evidently closely related to Mazama cita Osgood, from which it seems 
to be only subspecifically separable, differing from cita in smaller size and 
somewhat in coloration.

This is one of the palest and smallest species of the brown brocket group, 
it being paler and somewhat smaller than even M. nemorwwaga. The external 
measurements given by Dr. Merriam for the male type are, total length, 
1125 mm.; tail vertebree, 140; hind foot, 273; height at shoulders, 572. 
The principal measurements of the skull of the male type, as given by Dr. 
Merriam, are as follows: Basal length, 163; occipitonasal length, 157; 
zygomatic breadth, 82; orbital breadth, 73.5; interorbital breadth, 44; 
maxillary toothrow, 50; antler, length from burr, 113. My own measure- 
ments of the adult female skull (paratype) from Apazote, Campeche, Mexico — 
(U. S. Nat. Mus. No. 108287) are: Total length, 181; condylobasal length,
