[77] “Adult male.—Similar to typical Hyloterpe apoensis, but paler throughout, with crown brownish instead of grayish; under parts canary-yellow instead of lemon-yellow; slightly smaller. Wing, 78; tail, 67; culmen, 14; bill from nostril, 9.2; tarsus, 17.5. ‘Iris brown. Bill black.’
“Adult female * * *.—Paler and dingier than the male; under parts pale canary-yellow from throat backward. Wing, 71; tail, 61; tarsus, 17.5.
“Remarks.—Specimens in the U. S. National Museum, collected on the Island of Siquijor, Philippine Islands, by F. S. Bourns and D. C. Worcester, are exactly like Basilan specimens taken in February, 1888, and must be included as belonging to this species. Lowland birds from Mindanao Island connect the forms apoensis and basilanica.” (Mearns.)
Specimens from Siquijor, although larger than true H. apoensis, seem to be nearly like this species in color. [↑]
[78] The titmouse of Sulu and Tawi Tawi is probably not true Parus elegans. [↑]
[79] The construction of a key to the species of silvereyes is rendered very difficult by the nature of the characters upon which a number of the species are based. Some of the species can be determined only by the actual comparison of specimens in fresh plumage. Immediately following the molt, the colors are bright and yellowish, but after a few months the feathers become much abraded and the colors become duller, dingier and greener. [↑]
[80] The identity of Porter’s Caluya specimen with Zosterops aureiloris is somewhat doubtful. [↑]
[81] Gould’s type came from “Manila,” its collector is unknown and Dicæum retrocinctum has not been found in Luzon by any recent collector. It seems probable that the type was not collected in Luzon. [↑]
[82] Steere did not record this species from Marinduque, but in Bourns and Worcester’s MS. notes I find the remark: “Doubtless also Marinduque.” Cf. also Worcester and Bourns, Distribution List, Proc. U. S. Nat. Mus. Washington (1898), 20, 560, no. 361. [↑]
[83] Sharpe’s original diagnosis of Dicæum sibutuense is as follows: “D. simile, D. trigonostigmati, sed gutture saturate schistaceo, macula dorsale aurantiaca distinguendum. Long. tot. 3.2 poll., culm. 0.45, alæ 2.0, caudæ 0.85, tarsi 0.5.” [↑]
