by Mr. Swinhoe in Hainan, and was originally described by Mr. Sclater from 

 Borneo. It is somewhat remarkable that C. suhfurcatus, nobis,*' has not 

 hitherto been observed in the Indo-Chinese countries, though a resident 

 species at Pinang. The allied western species (C. affinis), so common in 

 India, is, however included by Mason. 



[The title, C. batassiensis, J. E. Gray (Cuv. An. King. (Griffith), Aves, ii. 

 p. 60, 1829), founded on Latham's Balassian Swift (Gen. Hist. vii. p. 329), 

 takes precedence over C. palmarurn, J. E. Gray (Hardw. 111. Ind. Zoo. i. 

 pi. 35, fig. 1, 1832).]

"The Swiftlets which build the edible nests," remarks Mason, "are so 

 numerous in the limestone caves on the islets and islands of the Tavai coast, 

 that the Government revenue from the birds'-nest farm in 1847 was nearly 

 eleven thousand rupees ; but in 1849 it was more than four thousand rupees 

 less. At Mergui they are not so numerous. " 



[As has been elsewhere shown (Ibis, 1874, p. 132), this Swift must take 

 the title of francica, Gm. Mr. Wallace was the first author who published 

 the opinion that examples from India, Ceylon, Bourbon, Mauritius, the 

 whole of the Malay islands, the Louisiade Archipelago, New Caledonia, 

 Tahiti, and the Marianne islands, do not specifically differ. That naturalist 

 not considering the variations in size and slight variations in colouration 

 which are to be found occurring sufficient to justify specific separation. 

 Examples (C. spodiopygia) from Ovalau and Mango island (Fiji) can hardly 

 be separated.]
