He freely recognized the prior discoveries of, as he thought, Audubon, though really, as has since been ascertained, of Macgillivray; but Muller was able to perceive their systematic value, which Macgillivray did not, and taught others to know it.
Fuller knowledge has shown that Macgillivray was ill-advised in laying stress on the systematic value of adaptive characters, but his contributions to anatomy were valuable, and later investigators, in particular H.
Among the many species whose anatomy Macgillivray thus partly described from autopsy were at least half a dozen' of those now referred to the family Tyrannidae (see King 1 Archiv fiir Naturgeschichte, vii.
It has already been mentioned that Macgillivray contributed to Audubon's Ornithological Biography a series of descriptions of some parts of the anatomy of American birds, from Mac- gillivray subjects supplied to him by that enthusiastic naturalist, and whose zeal and prescience, it may be called, in this respect merits all praise.
