222 VISCOUNT WALDEN ON THE BIRDS 
united all the titles founded on examples from those localities under the Linnean 
designation. 2 
In deference to the opinion of Mr. Wallace (Ibis, 1865, p. 393), I have excluded 
C. moluccensis, G. R. Gray, although Professor Schlegel (/.¢.) does not admit its 
distinctness. A Ceram example of a female in my collection certainly does differ from 
all others within the range of C. indica, as stated above, in having the rump earthy 
brown, with the cross bars dark brown, without a trace of grey. If, however, the 
Moluccan species prove to be distinct it will have to take the title of C. cyaneopileata, 
Bonn. J. s. ¢. 
©. timorensis, Bp. (javanicoides, Temm. Mus. Lugd.) op. cit. Ixili. p. 948, is an 
excellent species, wing 6°25, but is doubtfully separable from C. chrysochlora, Wagl. 
l.c., ex Australia. 
C. augusta, Bp. op. cit. 1855, p. 209, described from an example of unknown origin, 
has not as yet been identified. Professor Schlegel (/.c.) states that it is based on C. 
indica in transition-plumage; but the diagnosis is undoubtedly that of an adult male. 
The Prince suggests that C. augusta may be the same as the Nicobar form of C. indica 
described by Mr. Blyth (J. A. S. B. 1846, p. 371), and treated by him as a variety of 
C. indica (Cat. Calc. Mus. p. 238, no. 440)". 
The titles Columba cyanocephala, Gm. tom. cit. p. 781, no. 56, nec no. 20, and 
C. cwruleocephala, Lath. Ind. Orn. ii. p. 610, no. 61, both founded on Latham’s Blue- 
crowned Turtle, Synop. iv. p. 655, no. 52, cannot be allotted, Latham’s description 
being too vague, and no species of Chalcophaps having been discovered in China north 
of the island of Hainan. 
Le Pigeon violet & téte rouge d’ Antigue, Sonn. Voy. Nouv. Guin. p. 112, pl. 67. 
Columba pulcherrima, Scop. Del. Fl. Faun. Insubr. ii. p. 94, no. 98 (1786), ex Sonn. 
Columba rubricapilla, Gm. S. N. i. p. 784, no. 62 (1788), ex Sonn. 
This bird is now known to be confined to the Seychelles. 
Cata@yas, G. R. Gray. 
151. CALG@NAS NICOBARICA. 
The Nincombar Pigeon, Albin, Nat. Hist. Birds, iii. p. 44, pls. 47, 48, “Islands of Nincombar near 
Pegu”’ (1740). 
Columba nicobarica, Linn. S. N. i. p. 283, no. 27 (1766), ex Albin ; Cassin, Un. St. Expl. Exped. 
p- 276. 
Hab. Philippine Islands (Peale). 
Seen by Peale in the Philippine Islands, but afterwards in greater abundance at the 
island of Mangsi. The same author states that the habits of this Pigeon, as observed 
on that island, were decidedly arboreal. 
1 Conf. Blyth, Ibis, 1868, p. 133. The Nicobar race appears to me undistinguishable.
