568 MESSRS. SpLATER AND SALVIN ON [May 2S, 



wallacii. Mr. Wallace has kindly furnished us with notes upon 

 some of the species, which are indicated by his initials. 



Fam. TuRDiD^. 



1. TuRDUS phjEOpygus, Cab. (PI. XXIX.) 



Cobati, Rio Negro, 1851, two examples, "eyes olive." In Sclater's 

 collection from Para. 



The young of this species has a good deal of black colouring on 

 the edges of the breast-feathers, which wear off in the adult, and 

 leave the breast pure grey. One of Mr. Wallace's skins is a bird of 

 the year and exhibits this plumage, which, however, is still more 

 strikingly shown in a still younger specimen in Sclater's collection, 

 shot by Mr. C. Bartlett on the Maroni River, Surinam, in the spring 

 of 1866, and represented in Plate XXIX. 



2. TuRDUs ALBivENTRis, Spix, Av. Bras. i. p. 70, t. 69 ; Cab. 

 Mus. Hein. i. p. 4 ; Cab. in Schomb. Guian. iii. p. 666. 



Turdus ephippialis, Scl. P. Z. S. 1862, p.l09 ; Cat. A.B.App. p. 358. 



Mexiana, Dec. 1848, one example. 



In reviewing the American Turdi for our proposed ' Index Avium 

 Americanarum ' we have clearly made out that Sclater's Turdus 

 epthippialis is the true T. albiventris of Spix, as determined by Ca- 

 banis, /. s. e. The bird hitherto called T. albiventris by Sclater is T. 

 amaurochalinus, Cab. Mus. Hein. i. p. 5. 



3. Turdus fumigatus, Licht. 

 Mexiana, Dec. 1848, one example. 



4. DoNACOBius ATRiCAPiLLUS (Linn.). 



Para, one example ; also obtained on the Upper Amazons, June 

 1850, one example. 



"This species frequents the reed-beds and low trees on the banks 

 of the Amazons, and has a very fine song." — A. W. 



Fam. Troglodytid^. 



5. Thryophilus leucotis (Lafr.). 



Thrxjothorus leucotis, Lafr. R. Z. 1845, p. 338. 



T. albipectus, Cab. in Schomb. Guian. iii. p. 673, et Sclater, Cat. 

 A. B. p. 20. 



T. galbruithi, Lawrence ; Baird, Rev. A. B. p. 131. 



Island of Marajo, Feb. 1849, one example. 



This example agrees with Cayenne skins of the species hitherto 

 called T. albipectus in Sclater's collection. But Lafresnaye's name 

 is the oldest and must be adopted. As to the distribution of this 

 species, see our note, P. Z. S. 1864, p. 345. 



6. Troglodytes furvus (Gm.). 

 Para, August 1848, one example.
