the 'Comparative Osteology of the Families of North- American Passeres/ 

 and now we find^ from a preparation of the skull of Artamus leucog aster 

 recently made by Professor Stewart, that in the bony olfactory capsule 

 and in the spine-like process of the palatines, Artamus is Shrike-like. 

 Consequently my proposal to place the Artamida near the Sturnidce 

 and OrioUda was altogether wi'ong. 



The Campophagida in their osteology prove to have little or no 

 affinity with the Laniida, but must be placed near the Muscicapidce. 



The Dicrio'idce, judging from their skulls, are also not Shrikes, but 

 aberrant Flycatchers. From their style of nest, they may be allied to 

 the Orioles, and their proper position can only be ascertained by a 

 careful comparison of the osteological characters of the Oriolidce and 

 Dicrnridce carried out by some competent anatomist. 



In concluding this Address, therefore, I proceed to submit my scheme 

 of the linear arrangement of the Class " Aves,'' in accordance with the 

 views propounded in the preceding pages ; and that this arrangement 

 can be tested by the recent classifications of Fiirbringer and Seebohm, 

 I have given a second Map (Plate XII.) of my arrangement of Birds 

 with the limits of Fiirbringer coloured in blue^ and Seebohm^s in red. 



The few diagnostic characters given below of the groups and families 

 are nearly all borrowed from the works of other writers, notably those 

 of Seebohm and Stejneger, whose synopses of characters are useful as 

 summarizing much of the work of their predecessors. The diagnoses 

 are, of course, not by any means exhaustive, and merely are intended to 

 detail some of the leading features of the principal divisions.
