Genus PROTONOTARIA Baird. 



Protonotaria Baied, Eep. Pacific K. R. Surv., ix, 1858, 239. (Type, Moiaaila 

 dtrea Boddaert. ) 



Medium sized MniotiltidaB with form essentially similar to that of 

 IMm.itheros, but wing-tii^ longer (decidedly exceeding tarsus) and feet 

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

 gray wings and tail, and white under tail-coverts, the inner webs of 

 rectrices mostly white). 



Bill decidedly shorter than head, wedge-shaped but with culmen 

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

 maxillary tomium with subterminal notch present but indistinct or 

 obsolete; culmen distinctly ridged but not elevated basally; gonys 

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

 fossffi broad but mostly covered by latero-frontal feathers, partly con- 

 cealing both the longitudinally oval nostrils and their narrow superior 

 operculum. Rictal bristles obsolete. 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 decidedly 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. 



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

 inner webs of rectrices white, back and scapulars (also pileum and 

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

 Goverts, and edges of rectrices graj'. 



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. 

 (Monotypic.) 



PROTONOTARIA CITREA (Boddaert). 

 FROTHONOTARY WARBLER. 



Adult male 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 yellowish olive-green, this sometimes 

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



' Frequently 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 occiput, the hindneck being yellow.
