When compared with a series of ten examples from Yezo and 

 Hondo, Japan, no constant differences can bo found. The Korean 

 birds average perhaps rather darker below than the Japanese, but 

 two of the latter are fully as dark, and one of the former is quite 

 light, being almost white below. A specimen from IVkin and 

 another from Shanghai also agree with individuals in this series.

In the preliminary paper describing the new forms in Mr. Jouy's 

 collection I diagnosed the Korean white-backed woodpecker, calling 

 it Dryobates leucotos coreensis; but while my paper was in press, two 

 months before it was published, Mr. Buturlin described the same thing 

 under the name of Dryobates leuconotus ussuriensis, from specimens 

 taken at Sidemi, in the southernmost part of Ussuriland, near the 

 Korean boundary. In the same paper I described as new Dryobates 

 leucotos iissurianus from central Ussuriland, a quite different form. 

 Mr. Buturlin's ussuriensis is the same as my coreensis, and the latter 

 therefore lapses into the synonymy of the former; but his name 

 ussuriensis preoccupied my name ussurianus used for quite a different 

 bird, which he has consequently renamed. Mr. Buturlin had the 

 kindness to straighten out the whole matter in correspondence, and 

 later published an account of this somewhat curious uomenclatorial 

 entanglement, at the same time taking the opportunity of more 

 clearly bringing out the differential characters of the forms. 



There are two males and two females of t his subspecies in Mr. Jouy's 

 collection, taken at Fusan on September 30, and October 3, L885. 



YUNGIPICUS KIZUKI SEEBOHMI (Hargitt). 

 SEEBOHMS PIGMY WOODPECKER. 



The collection contains a male of tins subspecies taken at Seoul 

 July •"). L883, and a female from the same locality taken <>n October 

 I 1. L883. 



YUNGIPICUS KIZUKI NIGRESCENS (Seebohm). 

 RIUKIU PIGMY WOODPECKER. 



Two female pigmy woodpeckers taken on Tsushima May 18 and 

 June 2, L885, appear to be referable to this form, rather than to 

 )'. /■. Icizuki of Kiusiu. They agree perfectly with a bird from 

 Miyakeshima.
