338 BIRDS FROM YEZO, JAPAN—STEJNEGER. 
b? Inner edges of remiges (as seen from below) pale drab-gray; longer under 
tail-coverts entirely white; breast and flanks white with well-defined 
longitudinal streaks of dark drab-gray-------------------- _H. griseisticta. 
a2 First (tenth) primary equal to, or longer than, longest primary coverts ; second 
primary shorter than fifth; wing less than 7o™™ (ALSEONAX)..-A. latirostris. 
In proportions, size, and shape of bill my specimens of H. griseisticta 
(as well as my H. pallens) agree very closely with H. sibirica, so that it 
is entirely out of question to keep them in two different genera or even 
“subgenera. In fact almost the only structural difference which I can 
detect is the slightly longer gonys in H. griseisticta, Iam, therefore, 
considerably perplexed at seeing Mr. Sharpe referring the latter to the 
genus Muscicapa, next to M. grisola, while separating M. sibirica as the 
type of Hemichelidon. It seems therefore probable to me that his M. 
griseisticta (Sharpe, Cat. B. Brit. Mus., tv, p. 153) differs from mine, 
being probably Bonaparte’s (or at least Tweeddale’s) Butalis manillensis, 
a name which Sharpe quotes in his synonymy, but rejects on account 
of there being a Muscicapa manillensis previously employed.* Judging 
from Tweeddale’s remarks (P. 4. 8., 1877, p. 694) there occurs in 
the Philippine Islands a gray Flycatcher in coloration very much like 
H. griseisticta, but with a pill more like M. grisola. Whether Mr. 
Sharpe or I are wrong in the identification of Swinhoe’s name, I cannot 
say, but I have had for guidance two Chinese examples, one collected 
by Mr. Swinhoe himself, in March 1861, at Amoy, and marked ‘ Musci- 
capa griseisticta” in his own handwriting, and until the opposite be 
proven I shall regard this specimen as perfectly typical, and with this 
the Japanese bird agrees in all the essential particulars. 
The measurements of the latter are as follows: Wing, 82™™; tail- 
feathers, 50 ™™; exposed culmen, 8.5™™; tarsus, 14™'; middle toe, with 
claw, 15.5 ™™. 
Hirundo dasypus (BonaP.). (185) 
g ad., Henson No. 153; Hakodate, May 16, 1884; U. 8. Nat. Mus. No. 120480. 
Breast pale, intermediate between “smoke-eray” and ‘“drab-gray” 
(Ridgway, Nomencl. Col., pl. ii, pp. 12, 13), exactly like adult and young 
specimens collected by Mr. P. L. Jouy at Fuji, Hondo, July 20, 1880. 
Phyllopseustes borealis (BLAS.). 
Phyllopseustes borealis xanthodryas (SWINH.). 
Material which has come to hand since I wrote my “ Results of Orni- 
thological Explorations in Kamtschatka, ete.,” and especially the five 
specimens in Mr. Henson’s collection, as well as the example obtained 
by Mr. Petersen at Nagasaki, have considerably shaken my confidence 
in Phyllopseustes xanthodryas as a good species. Three characters are 
“Mr. Sharpe seems now to have adopted Bonaparte’s name notwithstanding the 
earlier M. manillensis (ef. Ibis, 1888, p. 200) and from arecent examination of Philip- 
pine examples he still considers B. manillensis and B. griseisticta identical.
