Adult female. — Upper parts black with a strong gloss of metallic blue ; the 

 feathers of the forehead and anterior portion of the crown with dark carmine- 

 red tips which form a large frontal patcli, ending in a line with the posterior 

 border of the eye. Lores, sides of the head and neck bhick, glossed with metallic 

 blue like the back. Cheeks and throat cariuine-red, the extreme bases of the 

 feathers being black ; feathers of the foreneck glossy black, each with a minute 

 carmine-red spot at the very tip. Rest of the under-surface pure white, the 

 sides of the breast indistinctly barred with bhick. Thighs black with white tips. 

 Lesser upper wing-coverts metallic bluish black, rather duller towards the 

 base ; remaining wing-coverts, quills and rectrices dull black, slightly glossed 

 with oily greenish along the outer web. Axillaries and under wiug-coverts 

 white. Bill black, basal half of lower mandible dull reddish ; feet black. 



The male (No. 2212) agrees with the type except in being smaller and in 

 having the under wing-coverts variegated with black. Some of the feathers on 

 the foreneck show pale bniiy-brownish edges, a sign of immaturity. 



No. 2375 is a young bird with the throat and foreneck deep buff-yellow, and 

 without any red or black in the plumage. It differs from tlie young of P. g. 

 gularis (Linn.) and P. g. cervicalis Scl. by its much darker, fuliginous (instead of 

 pale brown) back, and by having the sides of the head dark smoky brown (not 

 brownish bufl'). The bill, too, is decidedly stronger. 



P. baeri is nearly allied to, but quite distinct from, P. <j. gnlnris (Linn.), from 

 which it may be distinguished by the following characters : The red of the forehead 

 and throat is much deeper, carmine-red (instead of " poppy-red," Ridgw. vii. 9); the 

 feathers of the forehead and anterior portion of the vertex are only tipped with 

 red, the bases being black, while in P. g. gularis all the top of the head (from the 

 forehead to the nape) is uniform clear poppy-red, there being no blackish bases 

 to the feathers ; lores and sides of the head metallic liluish black (not poppy- 

 red as in P. g. gularis), sides of the neck bluish black like the back (not 

 white as in P. g. gularis) ; occiput, back and wings much more glossy ; sides of 

 the breast and abdomen with subterminal cross-bars of blackish, entirely absent 

 in the Guianan species. Another very striking difference consists in the shape 

 of the feathers of the foreneck. In P. g. gularis these feathers are elongated, 

 somewhat pointed and black, with the concealed bases dull reddish ; in P. baeri 

 they are much shorter, rounded and dull black, each with a minute glossy spot 

 of carmine-red at the extreme tip. The bill of P. baeri is decidedly stronger and 

 stouter, and the lower mandible dull reddish (not clear yellowish white as in 

 P. g. gularis) with the tip blackish.
