256 PROCEEDINGS OF THE ACADEMY OF [Juiie-Oct., 



"List." As a matter of fact, in all editions of the "List" we find on 

 the title page "with an indication of the typical species of each genus'' 

 and the citation of a species in any edition is rightly regarded as a type 

 designation for the genus under which it is quoted. Where two names 

 are cited as above the second is obviously intended as a synonym of 

 the first and is usually a reference to a plate or figure of the species. 

 Gray's own statement on the title page, moreover, proves that he was 

 citing but a single species under each genus. 



In the present case he misidentified the Cynanthus latirostris of 

 Swainson, thinking it the same as Orthorhynchus amizili Lesson, and 

 did not correct his error until the 1855 edition. Upon this basis 

 C. latirostris becomes the type of Amizilis Gray, 1840, which, there- 

 fore, becomes a synonym of Cynanthus Swainson, 1827. 



Amazilia Lesson, L'Echo du Monde Sav. ser. 2, viii, No. 32, Oct. 

 22, 1843, col. 757, seems to be the first name available for the present 

 genus. Mr. Ridgway (Birds of N. and Mid-America, vol. V, p. 405) 

 quotes five species as mentioned by Lesson, and of these I would 

 designate Ornismia cinnamomea Less. ( = 0. rutila DeLattre) as the 

 type of Amazilia Lesson.
