term. Gray, however,' evideutly considers it as such, as witness 

 some notes sent l^y Mr. Witmer Stone, who kindly verified the 

 original reference: " On page 107, in footnote to Genus Polytmus, 

 he [Gray] says that it includes a number of genera of various 

 authors, among which he gives ' Les Amizilis Less. (18?9),' appa- 

 rently quoting the above and misspelling it. On page 108, in the 

 list of species of Polytmm he gives under P. [olytmus]. amazili 

 (Less.), ' Type of Amizihs Less. (1829);' referring to the same 

 again and turning it into a Latin name." The following year 

 Gray again makes use of the term AmiziU.^ " Lesson,"" this time as 

 a generic heading, under which are placed the species A. latirostris 

 (Sw. ) and Or. amizili Less, There thus appears to be no reason 

 for the non-acceptance of Gray's Amlzilis — the type of which may 

 properly be considered to be Orthorhi/nchus amazili Lesson — 

 whether we allow the genus to date from 1840 or 1841, since in 

 either case it is several years anterior to Amizilia Reichenbach. 



Tiie species for which Mr. Salvin uses the name pridina Gould, 

 should be called amizili Lesson,^ this being its eai'liest name. The 

 species commonly known as viridiveniris Reichenbach is a parallel 

 case, its proper name being viridigastra Bourcier/ The forms, 

 erythronota, felicire and alicice are. distinguished from tobaci by 

 characters too slight and inconstant to entitle them to more than 

 subspecific rank. 



The species are 



Amizilis amazili (Lesson). 



Amizilis lencojyhcea (Reichenbach). 



Amizilis alticola (Gould). 



Amizili'^ diimerili (Lesson). 



Amizilis cinnamomea (Lesson). 



Amizilis cinnamomea saturata (Nelson). 



Amizilis graysoni (Lawrence). 



Amizilis berylli)ia (Lichtenstein). 



Amizilis devilii (Bourcier). 



Amizilis castaneiventris (Gould). 



Amizilis cyanura (Gould).
