Canon Tristram has kindly lent me this unique and inter- 

 esting bird. Before seeing it I was inclined to think that 

 its affinity to Dryocopus martins would be closer than to the 

 members of the genus Thriponax ; but such is not the case, 

 and I observe that this has been appreciated by Canon 

 Tristram, who, in writing to me, places it in the present 

 genus. The only known specimen is a female, and was pro- 

 cured by Lieut. E-ichards, R.N., in the island of Tzus Sima, 

 situated between Japan and the Corea. It will be interesting 

 to know the characters possessed by the male bird. The 

 type specimen of the present species (but for the absence of 

 red on the head) very much resembles the female of Th. 

 hodgsoni, but it has the white both above and below more 

 extended than in the latter species. The primaries arc 

 mostly tipped with white, a character possessed by many 

 species of Thripnnax, but absent in Dryocopus.
