species of the Family Icteridse. 149 



Guatemala, Chisec {Salvin) ; Brit. Honduras ; Costa Rica 

 {Carmiol); Panama [McLeannan) . 



This fine Cassique is distributed throughout Central Ame- 

 rica from S. Mexico to Panama. I have never seen it from 

 south of the isthmus, where 0. guatimozinus takes its place. 



2. OsTINOPS BIFASCIATUS. 



Cassicus bifasciatus, Spix, Av. Bras. i. p. 65, t. 61. 



Psarocolius bifasciatus, Wagl. Syst. Av. sp. 2. 



Ostinops bifasciatus, Cassin, Pr. Acad. Sc. Phil. 1860, 

 p. 139, et 1867, p. 71 ; Scl. et Salv. Nomencl. p. 35 ; Pelz. 

 Orn. Bras. p. 192. 



Similis O. montezumae, sed abdomine cum tibiis et crisso di- 

 lute castaneis diversus. 



Hab. Lower Amazonia (S/jia:) ; Vuvvl {Natterer). 



Mus. Academiae Philadelphise et Vindobonensi. 



This Cassique has been united by Dr. Cabanis and other 

 writers to C. montezumce ; but Mr. Cassin has shown that the 

 two birds are quite distinct, though nearly allied. 



I am not awai'e of the existence of any specimens of 0. bi- 

 fasciatus in Europe, except the type in the Munich Museum 

 (if that still exists) and Natterer's single example at Vienna. 

 It is certainly a very rare species.
