14 1 PASSERES. 



127. CHELIDON DASYPUS. 

 (BLACK-CIIINNED MAllTIN.) 



Chelidun dasyptis, Bonaparte, Consp. Generum Avium, i. p. 343 (1850). 



The Black-chinned Martin has a much less forked tail than the 

 European IIouse-^Martin ; and the black on the head descends 

 farther ])clo\v the eye to the upper part of the ear-covcrts and the 

 base of the chin. 



Figures : Swinhoe, Ibis, 1874, pi. 7. fig. 1. 



The Black-chinned Martin is the Japanese representative of our 

 House-^Iartin, and is a very common summer visitor to all the 

 islands, breeding on the cliffs and in the caves. It was first obtained 

 in Japan by Captain Blakiston, and erroneously described as a new 

 species under the name of Chelidon blakistoni (Swinhoe, Proc. Zool. 

 Soc. 1862, p. 320). There are several examples from Ilakodadi in 

 the Swinhoe collection (Whitely, Ibis, 1807, p. 19G), and there is 

 a large scries in the Pryer collection from Yokohama. 



It spends its summers in Japan and winters in Borneo. It 

 breeds in considerable numbers on the sides of an inaccessible cliff 

 on Fnji-yama, above the limit of forest-growth (Jouy, Proc. United 

 States Nat. Mus. 1883, p. 290). Eggs in the Pryer collection do 

 not difi'cr from those of the European House-Martin. 



128. COTYLE RIPARIA. 



(SAND-MARTIN.) 



JUnimh) riparia, Linneu><, Syst. Nat. i. p. 344 (1700). 



The Sand-Martin is a smaller bird than any of the other Swallows 

 of Japan. Its upper parts and a band across the breast arc brown ; 

 the rest of the undcrparts arc nearly white. 



Figures: Dresser, Birds of Europe, iii. pi. 103. 



The Sand-Martin is a summer visitor to Japan, but is nowhere 

 very abundant (Blakiston and Pryer, Ibis, 187<S, p. 231). I have 

 four examples sent me by Captain Blakiston from Yczzo (Sccbohm, 

 Ibis, 1879, p. 30) ; and there are two examples in the Pryer col- 

 lection from Yokohama. 



The Sand-Martin is a circumpolar bird, breeding in the British 

 Islands and across Europe and South Siberia to Japan, whence its 

 ran^'c extends on the American continent as far east as Baffin's H;iv.
