III tlie lioview (p. 200) several variatinns in this species are noted ; l»nt at 

 that time there was not a siitHeient niniiher of specimens to warrant our 

 coming to a cone liisi«>n as to their value. Now, however, we have hetter 

 material hel'ore us, and upon the examination of Jilxnit tliirty s})eeiniens, in- 

 chuHnu two series of nearly equal numbers, — one from tlie Atlantic States 

 and the West Indies, the other from tiie Mis.sissippi region and Middle 

 America, — tind that there are two appreciably different races, to be distin- 

 guished from eacl ■■^inKi ' ^«oints of constant ditference. All birds of tlu; 

 tiist series have tii '; i 1 " ;- ■ tlmn any of the latter, the ditference in a 

 majority of the s]»ecime i , 'tij' very considerable ; they also have the super- 

 ciliary stripe briLi^^ht yciu:". .^^; ,nlv, while amonu the latter there is never 

 more than a trace of yellow over the lores, and even this minimum amount 

 is discernible onlv in one or two individuals. The West Indian form is, of 

 course, the true (huniitlni, and t«» be distinguished as var. doiniiurn ; as none 

 of the synonymes of this species were fouiuleii u]>on the Mexican one, how- 

 ever, it will be necessary to propose a new name ; accordiuLjly, the term var. 

 albi/ofif is selected as beinu most descriptive of its j)eculiar features. 



The folh)wini; synopsis, taken from typical specimens, shows the dilfer- 

 ences between these two races : —

 known. Its geoorapbicid distribution is irreuuhir and ;i]t])arcntly eccentric. 

 Found occasionally, rather than fre([Ueutly, in the Sotithern Atlantic and (lulf 

 States, it oc«'uvs irrenidarly us far nortb as Washiniiton, Xev York (Mty,

 po.sed also occtisionally to breetl. \Yest of this it has not been traced in iiiiy 

 portion of the l'nited States. It was obtaine«l in Tamaidi])as, Mexiccr, by 

 laeutenant Co ch, and on the western c(»a. Mr. Xantus found it at Colima. 

 Mr. Sclater has also procureil it from other portions of Mexico, and M. l)ou-
