breadth of braincase, 65, 67; length of nasals, 67.5, 69; breadth of nasals, 23, 24; 
maxillary toothrow, 61.5, 73.5; m‘~*, 27,42. While the condylobasal length is 8 mm. 
less than in the Guiana skull, the zygomatic breadth is 8 mm. more, and the length of 
the maxillary toothrow 12 mm. less. On the other hand the braincase and occiput 
are narrower. 
The short toothrows and the short preorbital length, combined with the 
great zygomatic and orbital breadth are features that may require confirma- 
tion by additional material, but the two skulls from Tumatumari both 
differ similarly from the Rio Juruan one, and the difference is unusual, both 
in kind and degree, from ordinary individual differentiation. There is also 
much difference in the coloration from that of either twumatumarz or ameri- 
cana.

The seven specimens of red brockets obtained on the Roosevelt Expedi- 
tion to South America in southwestern Matto Grosso are doubtless referable 
to typical Mazama rufa (type locality, Paraguay). Unfortunately the field 
numbers on the skulls were lost before the specimens reached the Museum, 
and hence the skins and skulls cannot be correlated with certainty. The 
specimens are as follows: Three females (2 adult, 1 young), Urucum, near 
Corumba, Dec. 6-13 (Miller and Cherrie); 4 males, 3 adult, 1 young (the 
latter skull only), Porto Campo, Rio Sipotuba, Jan. 7 (T. and K. Roosevelt). 
The field measurements of 2 males and 2 females (all adult) give the total length 
as follows: 9 1100, 2 1420, #1050, & 1350. 
Two adult female skulls from Urucum: Total length, 207, 217; condylobasal 
length, 198, 208; occipitonasal length, 175.3, 184; preorbital length, 107, 113; 
zygomatic breadth, 90, 93; orbital breadth, 86.5, 92.7; interorbital breadth, 44, 45; 
occipital breadth, 58, 59; breadth of braincase, 60.5, 59; nasals, 62.5 < 28.5, 66 x 
20; maxillary toothrow, 62.5, 61.5; m1, 29, 27.5. Ratio of preorbital to condylo- 
basal length, 54, 56.3. 
Three adult male skulls (the two larger with the teeth much worn) from 
Porto Campo: Total length, 213, 206, 209; condylobasal length, 203, 198, 196; 
occipitonasal length, 184, 172, 178; preorbital length, 111, 102, 106; zygomatic 
breadth, 90, 91, 93; orbital breadth, 92.5, 91.5, 94; interorbital breadth, 45.3, Ad, 
49; occipital breadth, 59, 57, 62; breadth of braincase, 61.5, 62, 62.7; nasals, 78.5 X 
28, 58.5 XK 21,65 X 26; maxillary toothrow, 60, 60.5, 59. The length of the antlers 
(from burr to tip) in two specimens is 94 and 78; in the other male the antlers had 
recently been shed when the animal was killed. Ratio of the preorbital to the 
condylobasal length, 55.4, 53.6, 55.6.
