The characters of Nannocnus seem to be, as stated by Stejneger, of no more than subgeneric value. [↑]

[17] All of the species of ducks here enumerated, except Marila marila, are represented in the Bureau of Science collection by specimens taken in the Philippine Islands, but with the exception of the abundant Dendrocygna arcuata these are adults only, in winter plumage. I have constructed keys and diagnoses from this material but for detailed descriptions I have depended almost entirely upon Salvadori’s monograph in volume 27 of the Catalogue of Birds in the British Museum. [↑]

[18] The white-faced tree duck, Dendrocygna viduata (Linnæus), has been recorded as a Philippine species; I believe it should be omitted from our list. [↑]

[19] Mr. W. Eagle Clarke informs us that he has received a specimen of this duck from Negros. [↑]

[20] The Phæthontidæ have the nostrils open and the interramal space feathered. No member of this family has been reported from the Philippine Islands. [↑]

[21] Through the interest of Mr. William Edmonds, teacher in the Batanes, a specimen of the tic-wee buzzard from Batan has been sent to the Bureau of Science. We are under obligations to Mr. Otto Sheerer for two live specimens of this species which were caught in Batan. Still another tic-wee buzzard was captured on board the U. S. S. Albatross in the vicinity of Camiguin Island, north of Luzon. [↑]

[22] The Sibuyan specimen was recorded as Falco peregrinus in Publ. Govt. Labs. (1905), 25, 11. [↑]

[23] Sharpe’s diagnosis is as follows: “F. similis F. melanogeni, sed nigricantior, subtus ubique cinereo adumbratus, et subalaribus axillaribusque nigris, lineis parvulis albis transfasciatis. Long. tot. 15.5 poll., alæ 11.6, caudæ 5.5, tarsi 1.9.” [↑]

[24] “The length of the bill varies considerably, some specimens, measured from the anterior margin of the cere, being only 30, others 34.” [↑]

[25] Sharpe’s diagnosis and remarks on this species are as follows: “S. similis S. umbratili, sed multo minor et omnino saturate brunnea, modo Scopino vermiculata et notata, sed regione auriculari rufo-brunnea concolore, et fasciis frontalibus et cervicalibus pallidis obsoletis.
