On the genus Icterus ofM. Brisson. 191 



feathers are nearly of an equal length ; and by their tail being m 

 general even. A singular peculiarity is also observable in the 

 same member ; the shafts of the feathers being for the most part 

 prolonged beyond the webs, and the webs themselves being 

 pointed instead of being rounded as in the other groups of the 

 subfamily. Their tarsi again evince a considerable decrease of 

 strength. All these characters present indications of a different 

 mode of life, and a different station in nature ; and they require 

 that the species in which they are found should be pointed out by 

 a separate name. I shall group these species together by the 

 following characters under the generick name of 



Leistes. 



Rostrum crassum, rectum, basi altum, mandibul^ inferioris 

 margine angulato ; naribus rotundatis membrano partim tectis. 



jilce ; remigibus 4"' extimis fere aequalibus longissimis. 



Cauda xqualis, rectricum apice angulato, rhachibus plerumque 

 prolongatis, nudis. 



Pedes mediocres, tarsis gracilibus.
