ON THE LATE PROF. GARROD S CONTRIBUTIONS 



Ibis, 1881, 

 p. 3. 



In the present article I propose first to consider those points in the 

 anatomy of birds first brought into notice, or worked out in large groups, 

 by Garrod, and secondly to consider the light thrown by these facts on 

 the correct collocation of various genera, or larger groups, as well as on 

 the arrangement of these latter into groups of a still higher power. But 

 I shall avoid, as far as possible, any comparisons with previously pro- 

 posed classifications, as it is not my wish to enter, in this place, into 

 discussions of that kind. Under each of these headings I shall endeavour, 

 as far as is consistent with clearness and conciseness, to preserve a 

 chronological order. 



I. On the Conformation of the Nasal Bones*. 



" In most birds the anterior margin of the nasal bone is concave, with 

 the two cornua directed forwards," these processes being " continuous 

 behind with the body of the bone and with one another, there being no 

 interruption of any kind between them. Such a condition is found in 

 Otis and the Gallinse proper ; and birds possessing the bone so 

 constructed may be termed holorhinal : in them a transverse straight line, 

 drawn on the skull from the most backward point of the external nasal 

 aperture of one side to that of the other, always passes in front of the
