1870. ] DR. O. FINSCH ON THE BIRDS OF TRINIDAD. 571 
nidad (Cat. p. 222). But in our Venezuelan specimens of S, rufi- 
pennis the whole of the inner web of the secondaries is rufous, 
whereas in this Trinidad one the secondaries are still brown on the 
apical third of the feather. The rufous on the imer web of the tail- 
feathers is also more extended in S. rufipennis. 
The nearly allied S. mawimiliani, Cab. ( pitangua, Neuw.), from 
Brazil agrees in size and colours, except in having a broad white 
frontal band; whereas in S. su/phuratus there exists only a narrow 
frontal line, the feathers of which are white with brownish shafts, 
the forehead therefore becoming washed strongly with white. 
S. maximiliani I got in a collection of birds from Ceara, in North 
Brazil, collected by Mr. Amandus Zietz of Hamburg. 
The southern 8S. bellicosus is easily distinguished by the much 
larger size. SS. sulphuratus of Burmeister (i. p. 461) belongs to 
this latter species, and not to S, maximiliant.

Two specimens, agreeing in size and colours with others from 
Costa Rica, Guiana, and Brazil. 
** The climatic variety or species” from Ecuador, which Dr. Sclater 
separated as M. chrysogaster (P. Z. 8. 1860, p. 281), does not 
merit a specific denomination. Our Guiana specimen shows the 
underparts darker yellow than that from Trinidad and Brazil. MM. 
mexicanus, Lafr., said to be larger, is also by no means a distin- 
guishable species. Our Brazilian one is as large as that from Costa 
Rica. Dr. Sclater himself mentions that Panama specimens (P. Z. 8. 
1864, p. 360) are ‘intermediate between M. mexicanus and M. 
chrysogaster of Ecuador, showing that these two forms pass into one 
another.” 
Megarhynchus chrysocephalus (Tsch.), Heine (Journ. f. Orn, 
1859, p. 345; Mus. Hein. ii. p. 65), from Venezuela, is, as Dr. 
Sclater already noticed, most probably this species, the true M. 
chrysocephalus of Tschudi being totally different. 
Whether M. ruficeps, Sw., indeed belongs to M. pitanguus, as 
usually adopted, seems to be still somewhat dubious. We possess a 
specimen having a large bright cinnamon-red patch on the vertex, 
without any inclination to yellow or orange.
