_Characters._--Adult: Resembles _D. o. monacha_, but slightly darker on crown, nape, and mantle; back more bluish and less greenish, underparts slightly darker chestnut. Differs from _D. o. townsendi_ by being paler and gray on crown, nape, shoulder, side of neck, and upper breast; abdomen and under tail-coverts slightly deeper chestnut. Differs from _D. o. oceanica_ by larger size; upper parts paler; abdomen and under side of tail deeper chestnut. I agree with Amadon (1943:11) that this subspecies is only doubtfully distinct from _D. o. monacha_ and that it might be advisable to unite these under one subspecific name. _Measurements._--Measurements are listed in table 27. _Specimens examined._--Total number, 14 (5 males, 9 females, 1 unsexed) from Caroline Islands, AMNH--Truk (Nov., Dec.). _Remarks._--The Micronesian Pigeon at Truk was observed by Kittlitz (1836:299) and later by Kubary at the islands of Lukunor and Nukuoro. Momiyama (1922:4) remarks that he did not see specimens from these two islands but concludes that they probably belong to the subspecies named from Truk. It is possible that birds at these two atolls have been exterminated, although adequate field investigations have not been made. There is little information published concerning the natural history of this subspecies. McElroy, who visited Truk in December, 1945, did not find the bird; however, he did not visit all of the islands in the group during his stay. =Ducula oceanica townsendi= (Wetmore) Micronesian Pigeon _Globicera oceanica townsendi_ Wetmore, in Townsend and Wetmore, Bull.
