Cii. — III tlio species oftliis genus the bill is coniciil and acute ; llic culinon very gently curved from tlio base; the comniisHure 

 sliglitlv concave. The notch when visible is further from the lip than in Dcndroica, but usually is cither obsolete or entirely 

 wanting. Hristles very short. The tarsi are longer than the middle toe. The tail is nearly even, and considerably sliorter 

 than the wing. 



The genus Sylvicda of Swainson was established on the Parus americanus in 1827, hut both 

 this nameand Chloris of Boie, 1826, were pre-occupied. Parula of 1838 has been changed by 

 Gray and Cabauis onaccount of the simihirity in sound to Farulus of Sjjix, 1824 ; but, considering 

 this diilerence of termination as sufficient lor distinguishing the two names, I do not follow 

 these authors in dropping the former. 



The species of this genus have somewhat the habits of titmice, one only however is found 

 in the United States. The following synopsis will serve to distinguish them : 

 Above blue, with a dorsal patch of yellowish green ; yellow beneath. 



Patch confined to middle of back. Throat pale yellow, with a brown patch. Rest of 



under parts white ; lower eyelid white P. americana. 



A small dorsal patch. Under parts reddish yellow. Nojjatch on the eyelid... P. pitiayumi.^ 



Entire back yellowish green. Throat and breast yellow, with a brown bar across the 



former. Tail unspotted. Belly and superciliary stripe white P. mexicana.-
