There are three labels attached to the specimen. Based on the plumage characters mentioned above, Two are original Owston Collection labels and the third is a Rothschild Museum label, which was added to the specimen on its arrival at Tring. One of the Owston labels is written in Japanese, probably by the collector, and despite poor handwriting revealed some new information about the bird (Fig. 2, Table 3.). The second Owston label gives the Owston Col- lection number (O. C. No) of 727. Collecting Location As mentioned by Ogawa (1905), the bird was col- lected near the sea- coast at Nishihara on Miyako- jima, Okinawa Prefecture (around 24°50ЈN, 125°19ЈE). Fig. 1.
