short time before dark its whistling call was heard on every side. Though 

 common this species is by no means easy to secure in good shape, as it 

 stays in heavy underbrush and is constantly on the move. If the hunter 

 waits patiently near a patch of guavas or bamboo thicket he will hear 

 a rather low but clear two-syllable whistle. This may be rendered by 

 the Tagalo name "piloy" perhaps as well as by any other word. This 

 is repeated four or five times with great deliberation, then follows a low 

 throaty "chuck/' also repeated several times. Calliope lias a pretty, low, 

 warbling song, but does not often favor the listener with his song. Even 

 the "piloy series may not be repeated by the same bird for half an hour. 

 However, another bird at some distance will answer with this plaintive 

 and far-carrying call note. To get sight of one means a long wait, and 

 then it is not at all likely that you can more than see the bird. At the 

 least noise it flies into the thickest part of its retreat. I was unable to 

 find anyone on Calayan who had a name for the species. A specimen 

 was purchased in Quinta Market, Manila, February 29, 1904. 



Hypsipetes fugensis Grant; Grant, Ibis, 1896, p. 113. 



Grant's statement that "the top of head and neck are brown, like the 

 bach-, instead of dark, slate gray" is misleading. The back is brown, the 

 feathers faintly edged with dark olive brown, and while the head and 

 neck are brown the feathers are edged with dark slate-gray, which makes 

 considerable contrast between neck and mantle. The birds of Fuga and 

 Calayan are identical, except that the latter have slightly longer bills. 

 Bills from nostrils, in eight males from Fuga, measure 0.63-0.71 (aver- 

 age, 0.68). In the same number of males from Calayan I find 0.69-0.78 

 (average, 0.72). Ten specimens of each sex from Calayan taken in 

 October yield the following measurements : 



Males: Wing, 4.70-5.10 (average, 4.93); tail, 4.50-5.04 (average, 

 4.80): culmen. 1.02-1.10 (average, 1.07); tarsus, 0.82-0.97 (average, 

 0.91). 



Females: Wing, 4.64-4.80 (average, 4.73) : tail, 4.35-4.64 (average, 

 4.53): culmen, 0.98-1.10 (average. 1.02): tarsus, 0.84-0.94 (average, 

 0.91). 



A specimen from Fuga has two white feathers in the crown. No. 

 3797, a male from Calayan, has the lower parts except chin and throat 

 crossed by narrow obsolete light bars and the mantle and back are simi- 

 larly barred. Otherwise the plumage is normal. 



The molt of body plumage was about over when we reached the 

 Islands, but the wings and tail often contained both old and new feathers 

 up to the first of November. 



The illustration of the "foot of Hypsipetes psaroides, to show tarsal 

 envelope without scutes" (Cat Bds., VI, p. 35), by no means represents 

 the condition in II. fugensis, for the tarsi of this species are certainly 

 scutellated in the specimens of our large series. Four specimens of H. 

 anianrotis from Nagasaki, Japan, also show scutellated tarsi. According
