T. illigeri Cab. & Heine,* synonymized with T. chrysocrotaphum by Dr. Sclater, 
is evidently quite a good form, differing by its white throat and by the possession 
of a distinct black moustachial stripe. I have examined the type in the Berlin 
Museum.

The type specimen, an adult male, obtained by Natterer in Jane 1830, is still 
unique in the Vienna Museum. Thanks to the kindness of Dr. von Lorenz, I have 
been enabled to examine it, and have come to the conclusion that it is more cor- 
rectly placed in the genus Todirostrum. The bill has very nearly the same shape as 
that of 7. fumifrons Hartl., but is somewhat shorter. In the species of Kuscarthmus, 
on the other hand, the bill is much longer, as well as strongly attenuated for its 
terminal portion, In coloration, 7. senex is perhaps nearest to T. schistaceiceps,— 
presents, however, many points of distinction. The back is much darker and duller 
green (instead of bright yellowish green) ; the markings of the wing-coverts and 
inner secondaries are much paler, whitish yellow (not deep olive-yellow); the 
cheeks, ocular and auricular regions clear isabelle (instead of dark slate-grey) ; the 
throat and foreneck white with distinct, thongh narrow, brownish shaft-streaks ; 
on the top of the head the slate-grey is confined to the forehead and occiput, 
while the hind-crown and nape are green like the back, etc., ete. Moreover, the 
bill and tail are much shorter. 
The type measures : wing 48; tail 34; bill 12 mm.]

“ Tris yellow, feet brown, bill black.” 
Agrees with the Araguaya specimen (Nov. Zool. xv. 1908. p. 42) in the dull 
green colour of the upper parts, and in having only the anterior part of the pileum 
mouse-brown, but the belly is clearer yellow with barely any greenish shade on 
the chest. 
This is not the first record of the species from Amazonia, for Chapman t+ has 
already listed. a specimen from Santarem. Count Berlepsch possesses a skin 
obtained by Dr. Hahnel on the Lower Amazons, but the exact locality is not 
indicated.
