REVIEW OP AMERICAN BIRDS. 



[part I 



I have nothing especial to add to the account of this species con- 

 tained in the " Birds of North America," except to say that tlie 

 dilferences there referred to in the length of the bill are seen in tlio 

 more recent specimens, and belong more particularly to soutlicru 

 skins. Dr. Brewer considers the eggs of the southern birl so ditl'er- 

 ont as to warrant their specific separation. I find it, ho\/ever, vory 

 difficult to express the differences other than as consisting in longir 

 bill and less degree of black beneath. 



This species is remarkable as occurring at Mazatlan and Coliniu, 

 and not in California or the Rocky Mountains. 





PARULA. Bon. 



Chloris, BoiB, Isis, 1826, 972 (not of MasuniNO, 1752). (Type Pur\u 



americnnus, L.) 

 Sylvicola, Swainson, Zool. Jour. Ill, Jnly, 1827, 160 (not of Humphrey, 



Mu8. Calonnianuni, 1797, 60). (Same type.) 

 Parula, Bon., Qeog. Comp. Cat. io3C. (Same type.) 

 Compsoihl ypis, Cai. Mus. Hein. 1850-51, 20. (Same type.) (Parula 



rejeotod as contrary to the Linnsean canons of nomenclature.) 



If Moehring's genera are rejected as made prior to the establish- 

 ment of the Linaajan binomial nomenclature, and by a non-binomial 

 author, there is, perhaps, no reason why Boie's name Chloris siioiild 

 not be adopted for this group. I, however, leave the matter in 

 abeyance for the present.
