Hein. p. 61) characterizes 31. cayennensis as "pileo pulchre flavo;" hut a specimen in our collection from Brazil has the vertical patch fiery-red as in M. similis, another one, from New Granada (Baranquilla), somewhat less bright, and a third specimen, from Guiana (Demerara), shows only a yellow patch, this latter being apparently a younger bird. Two specimens from Ceara, in North Brazil, agree; in one the coronal patch is dark red as in M. texensis, in the other much less vivid; both are males. I believe that 31. guianensis, Cab., is not specifically different from 31. cayennensis. 31. icterophrys, Heine (Journ. f. Orn. 1861, p. 197), notwithstanding Dr. Cabanis's suggestion that it is nothing else than M. columbianus in fresh-moulted plumage, I take to be a good species, distinguished by the yellowish tinge on the superciliary stripe and on the chin and throat; otherwise it resembles 31. texensis, having also a bright fiery-red patch on the head, and yellowish margins on the inner web of the wings ; but it is considerably smaller. We possess on old one from Baranquilla, and a young one from Bogota; the latter, being in moult, has no vertical spot, and the yellow on the belly is brighter yellow. 31. granadensis, Lawr. (Ibis, 1862, p. 11), is identical with this species. I must, however, remark that 31uscicapa trivirgata, Neuw., can scarcely be the female of 31. similis, because tbe Prince, a very accurate describer, as is well known, says "chin and throat yellow," and his measurements are much smaller. latit.

There is a great variation in tbe extent of the cinnamon-red colour on the inner web of the quills and tail. In one specimen the rufous colour borders only the inner web, is broad on tbe quills, narrow on the tail-feathers; in the other one the rufous colour is much brighter and much more extended, nearly as much as in S. rufipennis, Lafr., a species which Dr. Sclater also notices from Tri- |
