PHILLIPS — THE NOETHEEN VIEGINIA DEEE 
133 
The orbit width (greatest width of orbit) is also a reliable measure- 
ment, but when we come to mastoid width, there is a very marked 
difference. It is possible that this C. V. (7.102) may have been 
slightly effected by damaged mastoids, although all those skulls which 
appeared to have been chipped or injured in the mastoid region were 
thrown out. 
The nasal bones are, as might be expected, by far the least valuable 
character, showing nearly double the variation of the palatal length. 
The antler length is included merely to give an idea of the size of the 
individuals, and naturally shows a very great range of variation. 
With the 13 juveniles included (these were not included in any of the 
other measurements) the antler length is of course still more variable. 
The value, if value there is, in this study of a series of deer skulls, 
lies in the fact that all specimens come from a fairly well restricted 
locality, and that they were all measured by myself in the same way 
and with the same instruments. I wish that the number of specimens 
could have been still greater, but as it is, it appears large enough to give 
a fairly reliable answer to the question of the variability of the several 
measurements in adult males of the northern Virginia deer. It also 
gives a correct idea of the extremes of size which we may expect to 
find in this race.
