It is not possible, we think, to keep separate the two forms distinguished in Sclater's Catalogue under the above-given names. 201. PACHYRHAMPHUS CINNAMOMEUS, Lawr. Ann. L. N. Y. vii. p. 295. Remedios. The Brown Becards of this genus have been long a source of trouble to us, the question being whether they are distinct species or females of the group of P. niger. Sclater, in his Review of Tity-rince1, adhered to the former opinion; subsequently2 he adopted Dr. Cabanis's view that the brown birds are either females or young males3. It will be impossible to decide this question satisfactorily, except by tbe aid of resident observers ; but of late we have been inclined to swing round to Sclater's original theory. Mr. Salmon's specimens go to support this view, the one marked "male" showing the second spurious primary, the other marked "female" being without it, i. e. having this primary of its normal length. On the whole we think it best for the present to employ Mr. Lawrence's name for this northern red form (which extends from Guatemala to Colombia), and the term rufus (Bodd.) for the Brazilian bird, which seems to be its southern representative. If the brown birds are females and young males of the black forms, we ought occasionally to meet with intermediate specimens. But amongst the multitudes that have come before us no such intermediate specimen has ever occured. 202. PACHYRHAMPHUS VERSICOLOR (Hartl.); Scl. Cat. p. 243. (Mus. S.-G.) 203.

Remedios, Neche. Food, insects. The occurrence of this Central-American species so far south of Panama is new to us ; but it has been already recorded by Mr. Cassin from the river Truando (Pr. Acad. Phil. I860, p. 143). 1 See P. Z. S. 1857, p. 79. * Cat, A. B. p. 242. » Mus. Hein. ii. p. 88. |
