coloration. It needs only comparison with T. fiificirepfi Sol. from Bolivia, with 

 which it agrees in having the forehead and crown uniform pale hrown. It diflfers, 

 however, from the Bolivian species by its much longer and rather narrower liill, 

 bright cinnamon-rufous (not pale buffv brownish) back, chest and sides of the neck, 

 considerably darker rufous colour on wini;s and tail, fulvous-brown crissnm, etc. From 

 T. erythroplhalma (Wied) and T. ferrti/)ineigula (Belz.) (= sclateri Berl.) it is at 

 once known by its cinnamon-rufous back and by having no rufous whatever on the 

 top of the head, etc. 



I take great pleasure in naming tliis species after my friend Count Berlepsch, 

 to whom I owe so much of my knowledge of neotropical birds. Tlie Count has seen 

 the type, and agrees with me that it represents quite a distinct species. 



Unfoi-tunately, Mr. Baron sent only one specimen of this interesting form, 

 which adds a new genus to the Peruvian avifauna. 



Diglossa pectoralis unicincta n. subsp. 



Similar to D. pectoralis pectoralis Cab. from Central Peru, but at once known 

 by lacking the milky white breast-band, and in having the chestnut of the crissum 

 extended over the middle of the lower bidlv. 



Upper sm-face, including wings aud tail, glos.sy black, except rump and upper 

 tail-coverts, which are slaty-grey. Sides of the head and throat deep black, but 

 without any gloss ; broad mystacal stripe white, across the foreneck a broad pale 

 chestnut band; crissum and middle of the lower abdomen also pale chestnut, rest 

 ot uuderparts deeji black. Axillaries and under wing-coverts white. Thighs black. 

 Bill black. 



Type in Mus. Tring : cJ ad. Levanto, Northern Peru, 9000 ft. elev., November 

 13th, 1894. 0. T. Baron coll. 



Wing 71 ; tail 62 ; bill 13i mm. 



In addition to the type, there are two adults and one young in tlie Tring 

 Museum, and the British Museum contains three specimens. All were collected bv 

 Mr. Baron in October and November 1894 near Levanto, and are exactly alike in the 

 characters pointed out. 



This new form might almost be considered a distinct species, but since it evidently 

 represents D. pectoralis in North I'eru, it is better treated as a sub-species.
