34G MR, H. SWINHOE ON THE BIRDS OF CHINA. [May 2, 



of the islands off the south of Hainan, and not the preceding species, 

 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 rustic a, 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 H. 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, I860, 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. pi.) is easily distin- 

 guished 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 narrow- 

 ness 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 Linnaeus and Pallas applied their 

 names to H. rufula, Temm. (Gould, B. of As. pi.). The Hima- 

 layan species, H. nipalensis, Hodgs. (H. daurica, Gould, B. of As. 

 pi.), 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.
