DENDRORNIS.—XIPHOCOLAPTES, 183 
The first specimen obtained of this fine species was probably that brought to 
Washington by Lieut. Michler from the Isthmus of Darien!. To this bird Cassin did 
not give a name, nor did Mr. Lawrence to M‘Leannan’s first specimens from the Isthmus 
of Panama?; but the latter ornithologist subsequently ? described M‘Leannan’s speci- 
mens; and the bird has since been traced through the State of Panama and Costa Rica, 
to the Mosquito coast ® and the Nicaraguan province of Chontales °. 
The species is a very distinct one without near allies, the definite tear-shaped spots 
of the anterior portion of the body forming a prominent feature in its coloration. We 
figure one of M‘Leannan’s specimens. 
XIPHOCOLAPTES. 
Xiphocolaptes, Lesson, Rev. Zool. 1840, p. 269; Ridgway, Pr. U.S. Nat. Mus. xii. p. 1 (5th Feb., 
1890) ; Scl. Cat. Birds Brit. Mus. xv. p. 142. 
Xiphocolaptes is a large form of Dendrornis with similar structural characters, but 
with a long strong bill, the gonys of which is slightly decurved as in Picolaptes. Its 
range extends from Southern Mexico to the Argentine Republic. 
The number of species contained in it is very variously estimated. Mr. Sclater admits 
five, whilst Mr. Ridgway recognized twelve species and subspecies. As we are now 
treating, according to our views, with only one valid species, this great difference of 
opinion must be tested by an examination of a large series of specimens from South 
America—ground we must not trespass upon here.
