168 VISCOUNT WALDBN ON THE BIRDS 



To the flattened side of the maxilla is attached a plate which extends from the base 

 for two thirds of the length of the maxilla. In the thickness of this plate are six 

 narrow and shallow, almost perpendicular, grooves, coloured yellow in the dried 

 specimen. A similar plate has grown on the sides of the mandible, and is grooved by 

 narrower and more deeply cut diagonal channels. A narrow casque springs from the 

 forehead, which, somewhat swollen posteriorly, is compressed anteriorly into a blunt 

 broken edge. The commissure is much indented and broken. This description of the 

 bill applies to the adults of both sexes; but in the male the bill is longer and 

 deeper than in the female.

The adult male (nos. 1, 2) has the back, rump, upper tail-coverts, and wings dull brown, 

 with a bronze-green gloss. The primaries are brown, with a faint ferruginous fringe to 

 the outer webs, the secondaries with a bolder albescent edging. The head, neck, throat, 

 breast, abdomen, vent, thigh-coverts, and under tail-coverts, tawny. The throat, cheeks, 

 and ear-coverts black, and marked as in P. panini. The crest is more elongated than

 ferruginous band about one inch deep, and terminated by a black band glossed with 

 green of about two inches. A narrow ferruginous fringe terminates some of the rec- 

 trices. In the outer pair, and sometimes in the two outer pairs, the ferruginous band 

 is pale tawny, and does not run through the outer webs. 



The adult female (no. 3) has the wings, back, and tail as in the male, the rest of the
