REVIEW OF AMERICAN BIRDS. 



[part I. 



It still remains to be (k'tennined whether there is any essential 

 ftunilv diU'LTeuco between tiie typical Turdidse and the Saxicolidae, 

 and whether a rearrangonicnt of these groups, perhaps including 

 even the tijlciidee, may not be required. In any case, however, 

 that the Mijiadeslinse must be embraced iii the same series, I have 

 little question. 



The two genera of Plilodnnatinse, as restricted, with the common 

 characters given above, differ as follows: — 



PhrnopepUi. Crest narrow, pointed behind. Outer primaries broad, not 

 attenuated nor pointed at end ; tlie 1st half the 2d. Tail rounded, fan- 

 shaped ; feathers very broad, wider towards end. Bill feeble, rather 

 narrow, well bristled ; nostrils somewhat overhung by frontal feathers. 

 Sexes dissimilar ; male black ; quills with median white patch on inner 

 webs ; tail not varied. 



Ptilogonyx. Crest broad, and decumbent. Outer primaries narrow, attenu- 

 ated and pointed at ends ; 1st about one-third the 2d. Tail even or 

 cuneate, feathers narrower. Bill stouter, much broader, fewer rictal 

 bristles ; nostrils much exposed. Sexes similar ; color cinereous ; wings 

 not varied ; tail feathers with median white patch on inner webs.
