326 MR. p. L. SCLATER ON CHILIAN BIRDS. [Mat. 28, 



everywhere in Chili* ; the latter in the Andes, at a height of from 

 5000 to 10,000 feet. 



Genus T^nioptera. 



Tceniopt era py rope (Kittl.) is the only Chihan bird of this group 

 I am acquainted with. It is found along the coast as far north as 

 Copiapo, but is common in the south (Darwin). It is not a very 

 typical species of the genus ; and Messrs. Cabanis and Heine sepa- 

 rate it as Pyrope kittlitzii (Mus. Hein. ii. p. 45). 



Genus Muscisaxicola. 



Of this essentially Chilian genus I have lately given a synopsis 

 of all the species known to me in the 'Ibis'f. The fine series now 

 transmitted by Messrs. Philippi and Landbeck does not affect tlie 

 determinations there arrived at upon the faith of skins received from 

 Herr Leybold. The Chilian species of the genus are the following : — 



1. M. nigrifrons. Ph. et Landb. Wiegm. Arch. 1865, p. 101. 



2. M.*cinerea, Ph. et Landb. /. c. p. 80. 



3. M. mentalis, Lafr. et D'Orb. 



As I have already pointed out (Ibis, 1866, p. 58), M. macloviana, 

 of the Falklands, is a larger form of this species. 



4. M. Jlavinucha, Lafr. Rev. Zool. 1855, p. 59 = M.yiavivertex, 

 Ph. et Landb. /. e. p. 98. 



5. 31. rubricapilla, Ph. et Landb. I. c. p. 93. 



6. M. rufivertex, Lafr. et D'Orb. 



7. M. maculirostris, Lafr. et D'Orb. 



Octhoeca chilensis, Hartl. (Naum. 1853, p. 212), has been already! 

 correctly referred to M. mentalis (jr. av.), as I learn from a com- 

 munication from Herr Finsch. 



Centi'ites niger (Bodd.), a form allied to Muscisaxicola, widely 

 distributed over the southern end of the American continent, occurs, 

 according to Mr. Darwin, as far north as Copiapo. Another iso- 

 lated type, nearly allied {Muscigralla hrevicauda), is found on the 

 coast of Peru and Ecuador, and has been stated to occur in Chili 

 also§, but not upon very good authority. The locality of the skin 

 in my collection (1254a, Cat. A. B. p. 206) rests merely on dealers' 

 authority. I believe the specimen to be more probably from West- 

 ern Peru. 



Mr. Landbeck sends me an example of Arundinicola citreola, 

 Landb. (Wiegm. Arch. 1864, p. 58), which is certainly very closely 

 allied to Hapalocercus Jlaviventris (Lafr. et D'Orb). But my single 

 skin of the latter bird is not in very good condition, and I should 

 be unwilling to unite the two before examining other specimens.
