shorter. In two specimens (Nos. 905, 938) there is a narrow blackish line on 
the upper mandible, separating the whitish “teeth” from the yellowish colour 
of the culmen. 
The young female (No. 906) is even paler and duller red on the mantle, 
breast, etc., than the young male (No. 410); the feathers of the pileum are edged 
with pale red, and the prominent bright reddish yellow lamella at the base of the 
bill is altogether absent. 
The colour of the under tail-coverts is rather variable in P. d. sturmii. They 
are either all pale yellow (Nos. 447, 939), or the longer ones are clear rufescent 
brown, at least their apical portion. 
Nos. 488, 410, 589, 576, 906 are preserved in the Tring Museum, Nos. 939 and 
905 passed into the Munich Museum, while Nos. 447 and 938 have been incorporated 
in the collection of Count Berlepsch. 
P. b. sturmii, P. 6, bitorquatus, and the recently described P. b. reichenowi * 
form a natural group, replacing each other geographically.

' Specimens from the Madeira district in the Munich Museum, Natterer coll., 
agree with a good series from Parad and Maranhao excepting that the black stripe 
across the sides of the upper mandible immediately preceding the yellow basal 
lamella is perhaps slightly broader. In the principal character, viz. the greater 
portion of the lower mandible being yellow, they are exactly like Pard examples. 
P. inscriptus has evidently a wide range in Amazonia, south of the main valley 
of the Amazons. It is not uncommon in the vicinity of Para, where Natterer,
