Show 346 MR. R. SWINHOE ON THE BIRDS OF CHINA. [May 2, of the islands off the south of Hainan, and not the preceding as I had at first supposed. 66. HIRUNDO GUTTURALIS, Scop. ; Ibis, 1860, pp. 48,429. 1861, p. 30, 1863, p. 255, 1870, p. 240 ; P. Z. S. 1863, p. 287. Hirundo rustica, Ibis, 1861, p. 254, 328, 1863, p. 89, 1867, p. 411. Hirundo panay ana, Gmel. Syst. Nat. 1788, i. p. 1018. Throughout China and Formosa in summer. Like II. rustica, but much smaller and with broader bill. 67. CECROPIS STRIOLATA (Temm. & Schleg.). Hirundo daurica, Ibis, 1860, p. 48, 1863, p. 255. The striped-belly Swallows that abound in summer in Formosa and breed there belong to the species of this group found in the islands of the Indian archipelago. My specimens agree with one collected by Mr. Wallace at Flores. Seven specimens of this form show no signs of a white spot on the inner web of the outer rectrix. 68. CECROPIS JAPONICA (Temm. & Schleg.). Hirundo daurica, Ibis, 1860, p. 48 ; P. Z. S. 1863, p. 187. I believe my Amoy specimens to belong to this species, though I have not been able to compare them with skins from Japan. Hirundo erythropygia, Sykes, of India (Gould, B. of As. pl.) is easily distinguished from this by its deep rufous unstreaked rump, and by the faint narrow streaks of its underparts. An occasional specimen of our bird shows a faint white spot on the inner web of the outer rectrix. 69. CECROPIS ARCTIVITTA, n. sp. Hirundo daurica, Ibis, 1861, p. 328, 1863, p. 89 ; P. Z. S. 1863, p. 287. The striped Swallow that comes to Pekin to breed is of about the size of the Amoy species, but more faintly and narrowly striped on the underparts, and is easily distinguishable from that and all other species of this group that I have seen by the extreme narrowness of the rufous band across its rump. (Depth of band in C. japonica 1*2, in this bird *7). I was formerly under the impression that the Pekin bird was the true H. daurica, L. (H. alpestris, Pall.); but I have now no doubt that both Linn_eus and Pallas applied their names to H. rufula, Temm. (Gould, B. of As. pl.). The Himalayan species, H. nipalensis, Hodgs. (H. daurica, Gould, B. of As. pl.), has the rump-band nearly as narrow as in ours, but its broad rufous nuchal collar prevents its being confounded with ours. The white spot on the external rectrix is also occasionally seen in the Pekin birds. 70. COTYLE RIPARIA (L.); Ibis, 1861, p. 328, 1863, p. 89; P. Z. S. 1863, p. 287. Pekin in summer. |
