Protonotaria Baird, Rep. Pacific R. R. Surv., ix, 1858, 239. (Type, MotaciUa 

 citrcd Boddaert. ) 



Medium sized Mniotiltidse with form essentially similar to that of 

 JJelmithero.s^ but winjj-tip longer (decidedly exceeding tarsus) and feet 

 weaker, and coloration very different (yellow, with olive-green ))ack, 

 gray wings and tail, and white under tail-coverts, the inner wel)s of 

 rectrices mostly white). 



Rill decidedly shorter than head, wedge-shaped ])ut with culmen 

 obviously curved, compressed (conspicuously so for terminal half), the 

 maxillary tomium with subterminal notch present ])ut indistinct or 

 o])solete; culmen distinctly ridged but not elevated basally; gonys 

 slightly shorter than distance from nostril to tip of maxilla. Nasal 

 fossae broad l)ut mostly covered by latero-frontal feathers, partly con- 

 cealing both the longitudinally oval nostrils and their narrow superior 

 operculum. Rictal l)ristles olisolete. Wing rather long, rather 

 pointed (ninth, eighth, and seventh primaries longest, the ninth slightly 

 shorter than seventh); wing-tip long, much exceeding length of tarsus. 

 Tail slightly shorter than distance from bend of wing to tips of second- 

 aries, slightly rounded. Tarsus decidedl}' longer than commissure, 

 its scutella indistinct (sometimes fused on outer side); middle toe with 

 claw much shorter than tarsus; lateral toes with claws falling short of 

 base of middle claw; basal phalanx of middle toe united for most of 

 its length to outer toe, for more than half its length to inner toe. 



Colorathyn. — Yellow, with under tail-coverts and greater part of 

 inner webs of rectrices white, l)ack and scapulars (also pileum and 

 hindneck in females) olive-green, wing-edgings, rump, upper tail- 

 coverts, and edges of rectrices gray. 



Nidification. — In holes of stumps or trees. 



Range. — Humid division of Upper and Lower Austral life-zones, 

 in swamps and wet bottom lands; in winter south through Mexico 

 and Central America to northern South America and to Cuba.

PROTONOTARIA CITREA (Boddaert). 

 PROTHONOTARY WARBLER, 



Adult mcde in summer. — Head, neck, and under parts (except under 

 tail-coverts) rich yellow (varying from lemon to cadmium, usually 

 nearer the latter), the head sometimes tinged or flecked with cadmium 

 orange; back and scapulars plain 3'ellowish olive-green, this sometimes 

 extending anteriorly over hindneck and occiput; ' rump, upper tail- 



' Fre(}uently the entire hindneck and occiput are pure yellow, abruptly defined 

 against the olive-green of the back; more often there is more or less of a patch of 

 yellowish olive-green on the occi^nit, the hindneck being yellow.
