d. Four middle rectrices much narrower than the rest, with webs strongly 



deflected, their shafts very large and broadly and deeply grooved on 



underside. (CampepMlese.) 



e. Gonys nearly four times as long as mandibular rami, its base covered by 



the long, closely appressed, antrorse feathers of chin; bill broad and 



much depressed, much broader than deep at anterior end of nostrils, 



abruptly contracted (in vertical profile) terminally; tenth (ovitermost) 



primary less than half as long as ninth, very narrow (one-tenth as wide 



as long); outer webs of secondaries mostly white; larger (wing 230-356 



mm.) Campephilus (p. 164), 



ee. Gonys much less than four (often less than three) times long as mandi- 

 bular rami, its base not covered by feathers of chin, the latter not dis- 

 tinctly antrorse or else much shorter; bill much less broad and depressed, 

 its width at anterior end of nostrils little if any greater than its depth 

 at same point, or else {Cniparchus, part) gradually tapering to the 

 tip (in vertical profile); tenth (outermost) primary more than half as 

 long as ninth, broader (one-eighth to one-sixth as wide as long) ; outer 

 webs of secondaries black; smaller (wing not more, usually much less, 

 than 220 mm.). 

 /. Gonys more than three times as long as mandibular rami; longer pri- 

 maries narrow, straight, the tenth (outermost) but little more than 

 half as long as ninth, falcate; tail nearly three-fourths as long as 

 wing; crest pointed, recurved; iimer web of inner secondaries white. 



Ipocrantor (extralimital).& 

 ff. Gonys less (usually much less) than three times as long as mandibular 

 rami; longer primaries broad, more or less incurved terminally, the

 as long as wing; crest not pointed, or else not recurved (usually 

 "bushy"); inner webs of inner secondaries black. 

 g. Wing longer and more pointed, the longer primaries exceeding sec-
