deep blacky contrasting very conspicuously with the finely 

 mottled general surface; tail-bands obsolete. 



" Young. Darker (brownish black) markings prevailing in 

 extent over the lighter (nearly clear white) ones ; stripes be- 

 neath broad, brownish black, those on the flanks cordate and 

 transverse/' 



Mr. Ridgway appears never to have seen his "^var. atri- 

 capillus " from the western regions of North America ; but he 

 describes an adult female from Colorado which, though other- 

 wise agreeing with his " var. striatulus," shows " a single fea- 

 ther on the lower parts which is coarsely barred, as in the 

 eastern style, while all the rest are finely waved and marbled, 

 as in the western ;" and he has also occasionally met with 

 adult specimens obtained in the eastern states which agreed 

 in their markings with the western phase, which he has desig- 

 nated as " striatulus ;" but he suggests that these may have 

 been only migratory stragglers from more westerly localities. 



The second subgeneric group to which I propose to refer 

 is that to which Kaup assigned the name of Lophospizia (or, 

 more correctly, Lophospizias) containing L. griseiceps, L. tri- 

 virgatus, and L. indicus, the two latter of which Mr. Sharpe 

 treats as only doubtfully distinct from each other ; and as the 

 difference between them appears to be one of size only, I think 

 it may be useful to note some measui'ements, chiefly taken 

 from specimens in the British and Norwich Museums, and 

 commencing with those of the larger race {L. indicus): —
