These five specimens which belong to the Vienna Museum are quite distinct 
from Mr. Hoffmanns’ skins of 7. havxwelli. The upper parts are much more richly 
coloured, being deep cinnamomeous or ochreous brown, the axillaries and under 
tail-coverts bright orange, the inner webs of the quills broadly edged with 
ochraceous buff. The general colour of the under surface is also quite different, 
bright cinnamomeous brown passing into ochraceous in the middle of the abdomen ; 
the throat is buff, striped with russet-brown (instead of whitish, with olive- or 
earthy brown streaks), and the under tail-coverts are buff or ochraceous, broadly 
edged with russet-brown. The three skins from the Guaporé (Nos. 3-5) differ 
slightly from the Borba couple by having the middle line of the abdomen white, 
and the under tail-coverts also mixed with whitish. In this respect they agree 
with an adult from Itaituba, Rio Tapajéz.]

The adult male obtained at Humaytha in 1906 has been erroneously referred

Paris, and Tring Museums, including the types of J. modulator D’Orb. and 
Sarochalinus rufogularis Des Murs,* I have come to the conclusion that if modulator 
from Bolivia and rufogularis from Eastern Peru and N.W. Brazil (Teffé, ete.) be
