BANGS AND PENARD: SOME CRITICAL NOTES ON BIRDS. 29 



ever since has figured as Sayornis cineracea (Lafr.) or Sayornis nigri- 

 cans cineracea (Lafr.). 



Lafresnaye's description certainly does not fit the South American 

 black phoebe, but agrees exactly with his type-specimen now before 

 us, which is not a Sayornis but a Myiochanes, the wide bill, pale 

 lower mandible, and gray colors all being mentioned by Lafresnaye. 



We give the following brief description of the type, possibly a little 

 faded by long exposure to light: — 



First primary shorter than fifth and longer than sixth (from outside) . 

 Wing, 84; tail, 71; tarsus, 16; exposed culmen, 15. Crown well 

 crested, dusky; upper parts gray, about between mouse-gray and 

 deep mouse-gray of Ridgway, lores whitish; wings dusky, no conspicu- 

 ous wing-bands; tail dusky, outer web of outer rectrix whitish; 

 below mouse-gray, throat whitish and middle of abdomen white. 

 Most nearly like Myiochanes ardosiacus ardosiacus (Lafr.) but slightly 

 smaller, paler, and grayer in general coloration, with the throat whit- 

 ish, middle of belly white and outer web of outer rectrix whitish. 



Saj/ornis cineracea of authors, not of Lafresnaj'e, must become 



Sayornis nigricans latirostris (Cabanis and Heine). 



Heleodytes pallescens (Lafresnaye).

We do not hesitate to pronounce Campylorhynchus pcdlescens 

 identical with Campylorhynchus bcdteatus Baird of western Ecuador 

 and northwestern Peru. Lafresna\'e's t^'pe has two labels which read 

 respectively " Thryoi. pcdlidus ou pallescens .... (Florent Mexique ?) " 

 and "Camp, pallescens nob. rev. 1846, 93 (Mexique)." The doubt in
