throughout. Posteriorly viewed, the synsacrum of the eagle is 
angular, while that of the vulture is nearly square. 
YERTEPRAL 
There are 18 vertebrae between the skull and the synsacrum, 
and, if we allow 14 for the synsacrum. as in the chestnut-faced 
owl, the whole vertebral series will be the same in actual dis¬ 
position, sequence, and numerical totality, since the caudal series 
of the eagle consists of 8 vertebrae—7 ordinary and the pygo- 
style—the pygostyle here consisting, apparently, of a single 
vertebra, and not of two. as in the owl. With this latter excep¬ 
tion the vertebral series of these diurnal and nocturnal birds of 
prey exactly agree.
