Geotlilypis 



(No. 30,6TG.) Among some specimens from Guatemala, iDresentetl 

 by Mr. Salvin to the Smithsonian Institution, is one labelled Geo- 

 thhjpis macgillivrayi ; which,- however, by no means belongs to it, 

 and is of a species quite unknown to me. In form it is intermediate 

 between Geothlypis and Oporornis — having a pointed wing, a little 

 longer than tail ; the 3d quill longest, the 2d a little longer than 

 the 4th, the 1st about equal to it. The under tail coverts are as in 

 Oporornis, reaching nearly to the end of the tail. The legs are also 

 as in Oporornis. The upper parts are olive green, brightest towards 

 the tail ; the head above tinged wnth brown. The whole under parts 

 are yellow, less vivid on the throat, and tinged with ashy across the 

 breast. An obscure line from bill to eye, and the eyelids aro 

 yellowish-white ; a dusky spot before the eye. Bill horn color. 

 Legs yellow. It resembles the female G. trichas in the yellowish 

 throat, but the wings are longer and more pointed, etc. Length, 

 5.00; wing, 2.40 ; tail, 2.25 ; tarsus, .83 ; middle toe and claw, .67. 

 The wings are much too short for either 0. agilis or formosus, 

 though otherwise similar in form.
