Birds from the Andaman Islands. 135 



Since writing on Collocalia affinis (Ibis, 1873, p. 302) I have 

 had an opportunity of comparing it with Horsfield's type spe- 

 cimen of C. linchi, and I find that it in no way differs. Hi- 

 rundo fuciphaga was described by Thunberg from Javan ex- 

 amples ; and I have no doubt whatever that Horsfield^s C. 

 linchi = H. fuciphaga, Thunb. The diagnosis of H. fuciphaga, 

 ample in its details, applies in every respect to C. linchi ; while 

 the last phrase, '' differt ab H. esculenta cauda tota atra im- 

 maculata,'^ of itself marks the species ; for with the exception 

 of the white spots on the lateral rectrices, Moluccan C. escu- 

 lenta (Linn.) is barely to be distinguished from Javan C. linchi. 

 The synonymy of C. fuciphaga will therefore be as follows : —
