Cettia minuta only differs in size from Cettia cauturiens, 

 exactly as Cettia cantillans differs from Cettia cantuns. It 

 has been suggested that the smaller examples are the 

 females of the larger ones, but until a pair have been shot 

 at the nest of each of these species this view must be 

 regarded as somewhat doubtful. In both Cettia minuta and 

 Cettia cauturiens examples from South China, where the 

 species are said to be resident, are much more rufous, espe- 

 cially on the forehead and upper tail-coverts, than examples 

 from North China, where they appear to be migratory. The 

 types of both species are in the Swinhoe Collection, and 

 unquestionably belong to the rufous race of each species, 

 which are resident within the Oriental Region. I propose 

 to distinguish the less rufous race of Cettia minuta, which is 

 a migratory bird breeding in the Palsearctic Region in Corea, 

 Chefoo, &c., as Cettia minuta borealis ; and the less rufous 

 race of Cettia cauturiens, Avhich is also a migratory bird 

 breeding in Russian Manchuria, and possibly in Central 

 China, as Cettia cantariens septentrionalis . 



16. Regulus ckistatus. 



Three females procured at Chemulpo in September and 

 October, and one female at Soul in April. 



Corean birds agree with other Asiatic examples in the 

 slaty colour of the nape and upper back. 



17. Parus palustris. 



Two females from Soul, January. The Mars-h-Tit of Corea 

 has a very small bill (culmen *35 inch), like Parus brevi- 

 rostris, a moderately long tail (2*25 inches), like Parus 

 borealis; the black on the crown is intense and extends far 

 down the nape. The grey of the upper j)arts is darker than 

 in Parus borealis and Parus japonicus, and the pale under- 

 parts are much greyer. Taczanowski (P. Z. S. 1887, 

 p. 604) identifies the Corean Marsh-Tit with the Ussuri- 

 Yalley race of that species, and records it under the name of 

 Farus palustris crassirostris. My examples are much darker, 

 both above and below, than examples from the Ussuii.
