Genus CHAETURA Stephens 



Chaetura similis "Lawr." Salvin and Godman 



Biologia Centrali-Americana, Aves 2 (47) : 375, 376, January 1893. 

 =Chaetura vauxi similis Salvin and Godman, fide Phillips (MS.). 

 30840. Adult female. Duenas (near Ciudad Guatemala Antigua), De- 

 partment of Sacatepequez, Guatemala. February 6, 1860. Received 

 from Osbert Salvin and Frederick DuC. Godman, in whose private 

 collection it was No. 1558. 

 Salvin and Godman [op. cit.) indicate that Lawrence had discriminated 

 two specimens of this form (one from Tehuantepec) , first as Chaetura 

 gaumeri, later as C. similis. That our No. 30840 is one of the two is made 

 certain by the fact that Lawrence has himself written "=guameri [sic}, L" 

 on the oldest label, and "Chaetura similis/Type Lawr." on a more recent one. 

 The name Chcetura similis is not adopted by the authors, but treated 

 simply as an unnecessary synonym of C. vauxi. Since, however, it is as- 

 sociated with a reference to Lawrence and critical comments, Lawrence's 

 MS. name acquires at this point nomenclatorial validity.
