^ Five specimens. 



^ One specimen. 



■'' From a very poor skin, not admitting of detailed description. 



* No specimens seen by me from Veragua. 



^Actually based on specimens (now in the U. S. National Museum collection) 

 from Cartagena, Colombia, collected by Dr. A. Schott, of Lieutenant Michler's expe- 

 dition, the very same specimens l)eing the types of Dendroka vkillotl Cassin, 

 described two years later. Feuillee being a pre-Linna>an author, it matters not 

 whether his Sylvia erithachorides is the same bird as Baird's Dendroica erihtachorldes; 

 and the latter name being accompanied by a sufficiently good diagnosis of the form 

 must, on account of its priority, supersede the name Dendroica vieilloti Cassin.
