“This Brocket is readily distinguishable by its bright rufous colour, 
unreversed nape-hairs, and small size, as compared with its only near allies, 
M. americana and zetta.’’>— Thomas, l. c. 
A young fawn from La Palma, Colombia, eastern slope of the southern

Mazama rufina (Pucheran). 
Cervus rufinus PUCHERAN, Rev. et. Mag. Zool. (2), II, p. 561, Nov. 1851; zbid., 
Arch. du Mus. Paris, VI, 1852, p. 491, pl. xxx. ‘Vallée de Lloa, sur le versant occi- 
dental de la Cordilliére du Pichincha.”’ 
One specimen, an old female with teeth much worn, a topotype of the 
species, Mt. Pichincha, May 15, 1913 (Richardson). Reliable external 
measurements are not available. Skull, total length, 161.5; condylobasal 
length, 151; occipitonasal length, 142.5; zygomatic breadth, 72; interorbi- 
tal breadth, 36; mastoid breadth, 55.5; breadth of braincase, 51; ty 
toothrow, 48; m*%, 29. 
This specimen is practically a topotype, as Richardson collected it in 
“Vallée de Lloa.”’ It agrees with Pucheran’s description and plate, except 
that Pucheran says the front of the legs is blackish, while in the present 
specimen there is a mixture of white on the lower tarsus and digits, probably 
an individual variation. 
The hairs of the nape are not reversed, nor are they ina topotype of M. 
brincentt.

Represented in the present collection by a topotype (skin without skull). 
This species and Mazama rufina (Pucheran) of the high Andes of Ecua- 
dor resemble each other greatly and differ from all the other known red 
brockets in their small size and very dark coloration and in the long coarse
