Birds of Celebes: Treronidae. 
621 
800 miles of very mountainous country to the North. Ihe present species must 
be a very rare bird in the North. 
Count Salvadori places it next to C.pistrinaria Bp. of the Solomon Islands 
and C. vanwpcki Cass, of the New Britain group, which may be distinguished 
by their having the head above grey. C. aenea may be recogTiised from it by 
its bright bronze-green back; C. paulina by the same character and further by 
its orange-cinnamon nape ; C. pickeringi, which occurs in Talaut, by its grey undei 
tail-coverts and mealy bottle-green back and ivings.

Five specimens — three in the Dresden, two in the I ring Museum of 
this Pigeon were killed by our native hunters in November, 1893, on the island 
of Kabruang, Talaut. Compared with an example from Cagayan Sooloo, kindly 
lent to us by the Hon. Walter Rothschild, the Talaut birds display generally 
darker tints, slightly darker grey on nape, mantle and under wing-coverts, darker 
bottle-o'reen on back, wings and tail, and somewhat darker under surface, but 
apparently somewhat more white on throat. These differences may be racial, 
or seasonal, or individual.
