less whitish underparts ; the black bands on underparts all narrower and 

 less well marked; the black of under side of neck more restricted — not 

 reaching so far over breast; and the light colored stripes on sides of 

 neck yellower — less purely white — and more restricted. 



Color. — Adult $, head all round crimson, a small brownish patch just 

 over opening of ear ; upper parts dull brownish black ; two narrow yellow- 

 ish white stripes, extending from the red of head down sides of neck to end 

 of interscapulum ; jugulum black; lower breast and rest of under parts 

 buff-jellow, crossed by numerous black bands, which become less well 

 marked on middle of belly; lining of wing and whole under surface of 

 wing feathers, except the ends which are blackish, strong yellow (a shade 

 about between maize yellow and buff yellow) ; bend of wing slightly 

 touched with red ; under side of tail and outer edges of primaries olive. 



Adult $, similar to male, but throat black, and a large black patch on 

 top of head, which usually includes much of the crest ; no red on bend 

 of wing. 



Meastirejtients (in millimeters). 



Remarks. — The Guatemalan Ivory-bill as it i-anges southward gradu- 

 ally becomes smaller, with lighter bill, and darker, more yellowish, less 

 whitish, underparts and under side of wing. The two examples in the 

 present collection are from farther south than any other specimens I have 

 seen and represent the form C. guatemaleusis bitxans in its extreme. 

 The northern extreme — true C. guatemalensis — occurs in southern Mex- 

 ico, Guatemala, etc., and to this form all of the various names that have 

 been given to the species seem to apply. As has been said before, it is 

 a larger bird with more black on under side of neck and breast, heavier 

 black bands crossing lower breast, belly etc., and whitish or yellowish 

 white under side of wings and ground color of under parts.
