the inner curves of the latter. The circumference of the 
antler at the base just above the burr is 119 mm. In addition 
to the basal prong (that of the right antler being single and that 
of the left bearing a small additional point on its anterior face), 
there are on each beam three large tines and a small point on 
the inner side of the beam between the first two tines. The 
second tine is, on each antler, the longest. Both of these tines 
possess an extra point on the anterior face near the tip, and 
that of the left antler has also one on its outer face.’ 
Size: The specimens from Louisiana are unaccompanied by 
measurements, so that the following taken from the dry skins 
can only be considered approximate. The measurements of 
the four specimens are given in millimeters in order thus, — 
Nos. 91 11 type, 9112, 8622, 8623: length from nose to end of 
tail (exclusive of terminal hairs), 2072, 1995, 1856, 1695 ; tail, 
220, 253, 285, 240; hind foot, 490, 393, 375, 382; ear from 
Crown, —, 122, 130.5, 134.5. No. 9i12 is a young three-point 
buck captured Dec. 10, 1898 ; No. 8623 is a spike buck, and 
with No. 8622, a one-point buck, was taken March 4, 1899. 
Range: The lowlands of Louisiana, perhaps found through- 
out most of the Austro-riparian zone. 
Remarks : The Louisiana deer is more closely related to the 
little Florida deer (Odocelus virginianus osceola) than to the 
more northern races. Indeed, it is in general appearance but 
a larger and slightly paler representative of that animal. To 
the west of its range is another small deer, Odocalus texanus 
(Mearns), but, as Dr. Mearns himself states, it is not to be 
confounded with the Louisiana deer. From true Odocalus vir- 
Sinianus (Bodd.), the large size and proportions of O. loutsian@ 
are alone sufficient to distinguish it, while from Odocelus vir- 
gintanus borealis, which it equals in size, it is easily separated 
by the cranial and color characters here given.
