“Adult male. Above, except forehead and anterior portion of crown, black, with a strong gloss of steel- blue somewhat inclining to greenish ; forehead and anterior half of the crown deep chestnut, the feathers of the latter being bluish black in the centre ; lores deep velvety black ; cheeks and lower ear-coverts, chin, throat, and fore neck bright tawny hazel, inclining slightly to cinnamon, and becoming somewhat lighter towards the breast ; upper half of the ear-coverts and sides of neck bluish black, like the back, this colour descending on the side of the breast, forming a distinct semilune on each side, which partly separates the hazel of the neck from the rest of the under surface, which is of a nearly pure drab, each feather near the middle line of the body broadly, though not very distinctly, margined with white ; under wing-coverts and axillaries of a drab colour, similar to that of the breast, but darker ; wings and tail above black, with a faint gloss of steel-green ; the tail-feathers, except the middle pair, with an oblique oval white spot in the inner web towards the tips, those on the outer pair being the smallest. Total length, according to Namiye, 145 mm. ; stretch of wings 325 mm. ; wing 118 mm. ; longest tail-feathers 58 mm, ; furcation of tail 14 mm. ; exposed culmen 8.5 mm. ; tarsus 10 mm. ; middle toe and claw 15 mm.”
Hab. Liu Kiu or Loo Choo Islands.
WE have not seen this species, which has been described by Dr. Stejneger from a single specimen obtained by Mr. Namiye in the Liu Kiu Archipelago at Urassoimagiri on the island of Okinawa Shima. As Mr. Seebohm has already pointed out, it appears to be merely a somewhat larger race of H. javanica, with a wing of 4.6 indies instead of 4.4. which is supposed to be the limit in H. javanica.
Dr. Stejneger gives the following note:—“Our new species is much nearer related to H javanica than to H. neoxena, but differs from it not only in size, being, as it is, considerably larger, but also in coloration. The gloss of the upper surface is more greenish ; the brown of the throat is more chestnut the grey of the underparts deeper and less tinged with rusty ; the under tail-coverts darker and tipped with a pure white margin, not tinged with rusty as in the Javan bird. It should be remarked, however, that in the unsexed Specimen in the Philadelphia Academy these tips are nearly white. The tail of the present species is somewhat more furcate, but, in spite of this, the outer rectrices are less attenuated at the tip.”
The greener shades of the upper surface may be due simply to the wearing of the plumage, and the other characters given by Dr. Stejneger do not seem to indicate a race markedly distinct from H. javanica.
The description of this Swallow is copied from the paper of Dr. Stejneger (l. c.).
