It still remains to be determined whether ti ere is any essential 

 family difference between the typical Turdidae and the HaxicoUdee, 

 and whether a rearrangement of these groups, perhaps ineliuling 

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

 that the Myiadestinee must be embraced in the same series, I have 

 little question. 



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

 characters given above, differ as follows : — 



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

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

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

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

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

 webs ; tail not varied. 



Ptilogonys. 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.
