OSGOOD — pennant’s- MEXICAN DEER 
suggestion.® This designation, however, is subject to revision if the 
type proves to belong to a larger form than the one of the Valley of 
Mexico. Without direct comparison of specimens, it is unsafe to 
draw definite conclusions, but it seems very probable that the type 
will prove inseparable from similarly developed specimens of one of 
the larger, more northern forms, as the Texan or possibly the Louisianan 
deer, either of which could come under a broad interpretation of ^‘Mex- 
can.” This is a matter for decision by the future monographer of 
the entire group of white-tailed deer. The following measurements 
were taken from the type: Length of beam over curve, 570 mm.; 
circumference above burr, 165 mm.; distance between anterior points, 
8f-9 inches.

is stated “The horns figured by Pennant are in the British Museum, and 
were refigured by Hamilton Smith;” Brooke, Proc. Zool. Soc. Lond. p. 
919, 1878 — horns figured by Pennant regarded as probably those of “Cari- 
acus macrotis;” Alston, Biol. Cent. Amer., p. 113, footnote, 1879 — “It 
seems to me more probable that these antlers belonged to C. leucurus 
(Dough) which recent American zoologists consider to be a local race of 
C. virginianus; they much resemble the remarkable Nebraska head figured 
by Baird (Mamm. N. Am. p. 652, fig. 18).”
