BIRDS OF NORTH AND MIDDLE AMERICA. 7 



a<i. Bill relatively short, broad and depressed basally, its width at frontal antise 

 decidedly more than its height at same point, and nearly if not quite equal to 

 length of gonys; the latter decidedly less than half the distance from point of 

 mandible to malar apex. 

 b. Legs shorter, the middle toe (without claw) more than two-thirds as long as tarsus, 

 the latter much less than one-third as long as wing, 

 c. Bill stouter (thrush -like), less depressed basally, its width at frontal antise 

 slightly less than length of gonys; inner webs of remiges without light- 

 colored "pattern." 

 d. Outermost (tenth) primary smaller, not more than one-third as long as 

 ninth; tail emarginate or double-rounded; mandible relatively more 

 slender, with gonydeal angle less prominent. . . .Platycichla (extralimital) « 

 dd. Outermost (tenth) primary larger, two-fifths as long as ninth; tail strongly 

 double-rounded, with lateral rectrices shorter than middle pair; mandi- 

 ble relatively stouter (deeper) with gonydeal angle more prominent. 



Cichlopsis (extralimital) b 



cc. Bill weaker (more "flycatcher "-like), much depressed at base, its width at 



frontal antise equal to or greater than length of gonys; inner webs of remiges 



with a broad white or buff basal area, or "pattern." 



d. Bill longer, the exposed culmen decidedly longer than outer toe (without 



claw); acrotarsiuni divided ("scutellate") on inner side. 



Entomodestes (extralimital) c 

 dd. Bill shorter, the exposed culmen little, if any, longer than inner toe (with- 

 out claw); acrotarsium undivided Myadestes (p. 170) 



bb. Legs longer, the middle toe (without claw) not more than three-fifths as long as 

 tarsus, the latter nearly (sometimes more than) one-third as long as wing. 



Phaeornis (extralimital) d 



ffl Platycichla Baird, Review Am. Birds, June, 1864, 32 (more fully characterized on 

 p. 436). (Type, P. brevipes Baird, ^Turdus Jlavipes Vieillot.) The species of this 

 genus are all South American. Besides those usually referred to it are Platycichla 

 xanthoscelus (Jardine) and Platycichla leucops (Taczanowski), hitherto referred to 

 Turdus or Merula=Planesticus. 



6(?) Turdampehs Lesson, L'Echo du Monde Sav., 1844, 156. (Type, T. lanioides 

 Lesson, = ??). — Cichlopsis Gabanis, Mus. Hein., i, 1850, 54. (Type, C. leucogenys 

 Cabanis). — Myiocichla Bonaparte, Compt. Rend., xxxviii, 1854, 6; Notes Orn. Coll. 

 Delattre, 1854, 30. (Type, M. ochrata Bonaparte, = Cic/jZopsis leucogenys Cabanis.) 



Not having at hand a specimen of Cichlopsis leucogenys Cabanis for comparison with 

 Lesson's description of his Turdampehs lanioides I can not be sure whether the two are 

 identical or not. According to descriptions of the former, however, they seem to be 

 very different; and taking into consideration Hartlaub's statement (Rev. Zool., 1846, 

 3) that Lesson's bird is Aulia hypopyrrha (Vieillot) I think the name Cichlopsis Cabanis 

 should be used for the genus until it is clearly shown that some other name has 

 indisputable claim to replace it. 



c Entomodestes Stejneger, Proc. U. S. Nat. Mus., v, sig. 29, Feb. 23, 1883, 456, foot- 

 note. (Type, Ptilogonys leucotis Tschudi.) (Peru.) 



d Phseornis Sclater, Ibis, Jvdy, 1859, 327, in text. (Type, Muscicapa obscura Gmelin.) 

 (Peculiar to the Hawaiian Islands.)
