502 ON A COLLECTION OF BIEDS FEOM TIIE [1877- 



bill is full three inches in length, and the basal portion of the body-plumage is pure white. 

 Mr. Blyth has also stated that C. culminatus extends to Malacca (Cat. Calc. Mus. p. 89. no. 448 ; 

 Ibis, 1863, p. 368), and that there also occurs C. macrorhjnchus, Vieillot*. This last species 

 Mr. Blyth identified with C. tenuirostris, Moore, ex Bombay, but which Mr. Blyth [l. c.) asserts 

 was founded on a Malaccan skin. Two Malaccan examples (mus. nostr.) belong to C. tenuirostris ; 

 and I am not prepared off-hand to identify them ■^^ath C. vaUchis. Their chief character is the 

 form of the bill. In C. validus the bill gradually and regularly diminishes from the base to the 

 apex, and is much bulged throughout the course of the commissure. The culmen is rather 

 acute than broad and rounded, and the height of the bill is considerable f. In C. tenuirostris 

 the bill is longer, very much compressed, and flattened on the sides ; the culmen is broad and 

 rounded, and not acute. The height is also less, 0-70 as against 0-91. The length of the gonys 

 is greater. In colouring, the lower plumage is of a more ashy tint ; and the general dimensions 

 are less. The base of the feathers is white, as in C. validus. The British Museum possesses 

 examples of C. tenuirostris from both Borneo (Banjermassing and Labuan) and Sumatra.

Malaccan individuals do not differ. Raffles does not appear to have ever published the title 

 of Columba gigantea attributed to him by Mr. G. E. Gray (Columba;, B. Mus. p. 13). 



* What is C. macrorhynchus, VieiUot? I cannot find that Vieillot ever bestowed such a title, although Jerdon, Blyth, 

 and Bonaparte have aU used it. Mr. Blyth is clearly referring to C. validus; for later (Ibis, 1870, p. 171) he identified 

 C. tenuirostris with C. validus. 



t The contour of the bUl of C. validus is very much that of C. levaillanti {C.culnmiatus); but the culmen is not quite 

 so much arched.
