The upper outlines of the hill is considerahly more curved. The first primary is a good deal 

 shorter. The tail feathers are more acuminate, the inner wehs slightly concave at the ends. 



The differences most strongly insisted on by Swainson are in the wings, which here are shorter 

 and more rounded ; the first q[uill considerably shorter instead of decidedly longer than the 

 fifth. 



Specimens labelled Fhyllomanes chivi, {Lanius agilis, Licht.) by Oabanis, and received from 

 him, appear precisely the same in every respect. 



This species, if found in the United States, is certainly very rare. I have never seen a speci- 

 men, nor do I know of any preserved in any cabinet. It is not impossible, but* on the contrary, 

 very likely, that the "young bird" mentioned by Swainson as found on the banks of the 

 Columbia may have been the V. gilvus which occurs there, and which was otherwise unknown 

 to the author. The description is made from his Brazilian specimen. 



It is quite difficult to say which is the proper name of the present species, before ascertaining 

 whether more than one species be contained in the synonymy quoted above. The descriptions 

 of neither V. virescens nor chivi contain any positive specific indications, while agilis seems 

 unquestionably the same with the bartramius, of Swainson, from Brazil, and in any event will 

 have priority over it.

Sp. Ch. — Very similar to V. olivaceus, but with a short dusky maxillary line. Bill longer. 

 Hob. — The coast of Southern Florida and the West Indies. 



This species is very similar to the V. olivaceus in the olivaceous upper parts, and ashy crown 

 bordered on each side by a darker shade along the whitish superciliary stripe ; the plumbeous 

 stripe from the bill through and behind the eye ; the under parts white, with a faint tinge only 

 of yellow on the under tail coverts, and a stronger tinge of olivaceous on the sides. There is, 

 however, in addition to this, a narrow line of dusky ash or plumbeous, continuous with the 

 under side of the rami of the lower jaw, and extending back as far as the somewhat similar 

 stripe through the eye does. The tail is nearly even ; the second quill appears to be the
