and the male of the same bird is identified by Mr. Swinhoe with 

 M. muginaki, Temm. and Schl.j of the ' Fauna Japonica/ The 

 Ruticilla leucoptei'a, nobis, from Malacca and Java, is the true 

 R. aurorea (Pallas), v. R. reevesii, Gray, of China and Japan, 

 also occurring rarely in Assam. Xanthopygia tricolor (Hartlaub), 

 V. X. leucophrys, nobis, is another Chinese bird which occurs 

 rarely in Mai accan collections; but I leave to Mr. Swinhoe's 

 future researches the further development of instances of this 

 migration*. 



I should add that Sterna affinis, Horsf., is Gelochelidon anglica 

 (Mont.) ; and that S.javanica and S.griseal^ll.) are the summer 

 and winter dress of Hydrochelidon indica (Stephens), v. hyhrida, 

 Pallas, leucopareia^ Temm., &c. S. javanica has been erro- 

 neously identified with S. melanogaster , Temm., and with H. 

 fissipes (v. nigra) by Mr. Swinhoe in the ' Ibis,' 1863, p. 97. 



Of Colonel Sykes's Dukhun specimens in the India Museum, 

 Pratincola bicolor ( 6 Saxicola hicolor and $ S. erythropygia, 

 Sykes) is identical with P. atrata, nobis, of S. India and Ceylon ; 



* In the ' Ibis,' 1863, p. 92, Mr. Swinhoe mentions the Xanthopygia 

 leucophrys, Blyth, " of India." The species bears the prior name of Mus~ 

 cicapa tricolor, Hartlaub ; and it occurs rarely (and doubtless as a winter 

 visitant only) in the Malayan peninsula, but certainly not in India properly 

 so called. Sturnus dauricus, Pallas, is assigned to "India and Java" at 

 p. 95. This bird also inhabits the Malayan peninsula and southernmost 

 Tenasserim province of Mergui, as likewise the northern part of Sumatra, 

 but is quite unknown in India. Chibia hottentota (L.) " of the plains of 

 India " (p. 96) is there known as a winter visitant only- There must surely 

 be some mistake about Fregilus graculus occurring in Java (p. 95) ! No 

 specimen of this bird supposed to be from Java is in the "India Museum " ; 

 and it is most unlikely to occur anywhere within the tropics. Phyl- 

 loscopus fuscatus (p. 93) was so named by myself, not by Mr. Hodgson; 

 and P. coronatus of Japan is very closely akin to P. occipitalis, nobis, 

 of India, but differs by its white lower tail-coverts and one or two other 

 minute particulars, as the development of the minute first primary, sutfi- 

 cient to permit of ready discrimination. Cypselus subfurcatus, nobis, is 

 stated by Mr. Swinhoe (p. 254) to have a " less fui'cate tail than its near 

 ally, C affinis, J. E. Gray, from continental India." This is a mistake. 

 The tail of C. affinis is not at all furcate, whilst that of C. subfurcatus is 

 slightly so. Specimens of the latter from Pinang are undistinguishable from 

 those from China; and the supposed Hirundo urbica (apud Raffles), from 

 Sumatra, is in all probability no other.
