Keibigai, Taihoku Distr.: i£ & i<£, May 19; Shintengai, Taihoku : 

 4"£s & 1Ç, May 19. Very common. Some authors have erroneously 

 given that this subspecies occurs in Japan also. In Japan it is replaced 

 by H. daurica nipaleiisis Hodgs. 



96. Chelidon urbiea tiigritnentalis (Hartert). 

 \ Hime-iwatsubame. 

 Hirundo urbica nigrimentalis Hartert, Vög. Pal. F., I, p. 810. 

 A specimen of the subspecies obtained at Arisan, Aug. 19 12, and two 

 more obtained at Kanetowansha, Nanto Distr., Nov. 1 1, 1912, are preserved 

 in the Taihoku museum. The subspecies is closely allied to Ch. urb. kash- 

 miriensis Gould, but is smaller, the wing measuring only 92-96 mm. long. 



97. Cotile sinensis (J. E. Gray). 

 Chösen-shödötsubame.

Enteishò, Tainan Distr.: i"^, May 9. The bird was found to be com- 

 mon at Enteishò, Tainan Distr. Mr. Kikuchi tells me that he observed the 

 species in abundance at Horisha. Mr. Tada reported the occurrence of 

 Cotile riparia (L.) in Formosa, but I should doubt the correctness of his 

 specific identification.
