Of the genus Bubo I have examined in this connection, B. virgunianus 
and allied American forms, B. bubo, B. bengalensis, B. coromandus, B. 
lacteus, B. verreauat and B. maculosus. “ Bubo”’ lett of the ‘Hand-List,’ 
is, according to Sharpe (B. B. O. C., X, lv) referable to Scops (=Otus). 
In the two specimens of Pseudoptynx philuppinensis examined the cen- 
tral pair of tail-feathers is considerably shorter than the outer pair instead 
of being decidedly longer as in other Bubonidee. It has been stated that in 
the Barn Owls (Tytonide) alone, among Owls, are the middle rectrices 
shorter than the outer (Clark, Proc. U.S. Nat. Mus., XVII, 1895, 565). 
Uropsalis gen. nov. 
Type Hydropsalis lyra Bp. 
Related to Hydropsalis Wagl. and Macropsalis Scl.; differing from the former in 
having the central pair of rectrices shorter than instead of much longer than the 
next three pairs; from the latter in the much smaller wing, the outer three primaries. 
not specially enlarged, the tenth shorter than instead of longer than the ninth, three 
instead of only two primaries emarginate on the inner web; and in the broadly 
rounded instead of tapering and obtusely pointed tips of the first four pairs of rec- 
trices; the latter much less strongly graduated, the fourth pair exceeding the third. 
by less than one-half the length of the first pair instead of by more than the length 
of the first. ; 
In addition to the type species, Hydropsalis segmentata Cass. is also refer- 
able to this genus. ‘This species agrees with U. lyra in the form of the wing 
and differs from Macropsalis in the form of the tail even more than does 
U. lyra, the tail (omitting the outer pair of rectrices) being merely emarginate 
instead of strongly forked. 
While Dr. Sclater referred these two species to his subgenus Macropsalis, 
and this course has been followed ever since, they differ so conspicuously 
from the type and (as here restricted) only species of that genus, M. creagra, 
in the form of the wing and in the shape and graduation of the rectrices, 
that there is no question of their generic distinctness. In the form of the 
wing they agree with the shorter-tailed species of Hydropsalis (subgenus 
Diplopsalis), the longer-tailed species of that genus slightly approaching 
Macropsalis in this respect. 
In Uropsalis lyra the longest primary (the ninth) reaches 1,4; inches 
beyond the tip of the seventh, while in Macropsalis creagra (a bird of about 
equal size) the distance from the latter point to the tip of the longest (tenth) 
quill is three inches. The unusual development of the outer three primaries. 
in Macropsalis is to a large degree a sexual character, highly developed in the 
male only. In the female the eighth, and particularly the ninth and tenth 
primaries are much less enlarged, the wing in consequence being much shorter 
than in the male. In Uropsalis the wing is of the same length in both sexes.
