194 VISCOUNT WALDEN ON THE BIRDS 
Copsycuus, Wagler. 
106. * Copsycnus MINDANENSIS. (Pl. XXXIII. fig. 1.) 
Le Merle de Mindanao, Montb. Hist. Nat. Ois. iii. p. 387 ; D’Aubenton, Pl. Enl. 627. f. 1. 
Turdus mindanensis, Gm. 8. N. i. p. 823, no. 76 (1788), ex Montb. 
Copsychus mindanensis (Gm.), Sundevall, Kritisk Framst. p. 36, note (1857) ; v. Martens, J. f. O. 
1866, p. 10, no. 20; Walden & Layard, Ibis, 1872, p. 102, “ Negros.” 
Hab. Zebu, April; Guimaras, March (Meyer); Negros (L. C. Layard); Mindanao 
(v. Martens). 
Professor Sundevall (/. c.) was the first author who identified this purely Philippine 
species, which previously was, and since has continued to be, confounded with the 
Malayan, C. musicus (Raffles). 
In a Guimaras male (fide Meyer), otherwise in full plumage, the under shoulder- 
coverts are tipped with white. In Zebu and Negros examples of the male they are 
entirely black; in a Zebu female (fide Meyer) they are ashy; no white on the 
rectrices of any,—thus agreeing with Montbeillard’s account of his type, which was brought 
to Paris by Sonnerat, presumedly from Mindanao, although its origin is only to be in- 
ferred from the title. 
CALLIopPE, Gould. 
107. CALLIOPE CAMTSCHATKENSIS. 
Motacilla calliope, Pallas, Reisen Russischen Reichs, iii. p. 697, no. 17, “ Siberia” (1776). 
Kamtschatka Thrush, Latham, Synopsis, iii. p. 28, no. 14; Synop. Suppl. p. 140, tad. in titul. 
Turdus camtschatkensis, Gm. 8. N. i. p. 817, no. 58 (1788), ex Latham ; Blyth, Ibis, 1865, p. 30, 
« Philippines.” 
Mr. Blyth (/. ¢.) includes this bird among the Philippine species he observed im the 
Derby Museum at Liverpool. It is probably only a winter resident.

SYLVINA.

Gerygone simplex, Cab. op. cit. 1872, p. 316, no. 4 (descr. princeps).
