jo. Iriomote. June 15— 27. Kohama, a small island between Iriomote 

 and Ishigaki, was visited June 30. 

 On some of the islands, the services of native collectors were availed 

 -of. This accounts for the facts that in some cases the dating of specimens 

 does not agree with the time of the party's stay and that certain speci- 

 mens are from islands which were not visited by the party itself, as f. i. 

 Yonakuni. A number of specimens bear the date of Jan. 1905 ; they are 

 those that were collected by native hunters after the party's departure 

 from the islands. 



The entire collection consists of 1669 well-preserved skins, — a number 

 which speaks much to the credit of Mr. Osa and his assistant who made 

 it. This fine collection, coming as it does from islands which orni- 

 thologically had been but little or not at all known before, is of great 

 importance, and certainly demands a more careful and more prolonged 

 attention than that I have been able to bestow upon it. For the present 

 I am prevented by circumstances to improve upon this report, and so let it 

 be given as it stands. 



I have referred the specimens in the collection to 95 genera and 124 

 species and subspecies. As new species will be described the three, 

 Geocichla major (No. 2), Picus oiustoni (No. 59) and Nannocnus ijimai 

 (No. 92) ; and as new subspecies will be given likewise three, viz., Merula 

 celœnops yakushimensis (No. 7), Zostirops japonicus insularis (No. 23) arid 

 Corvus mctcrorhynchus osai (No. 37). New to the avifauna of the 

 Japanese Empire are Merops omatus (No. 70) and Spilornis pallidas (No. 

 83). The sequence adopted in listing the species is that of Seebohm in his 

 Birds of the Japanese Empire. 



At the end of the report is appended a Table containing a list of all 

 the species and subspecies hitherto recorded from the region, together with 

 indications of the island or island groups on which each was obtained. In 

 that Table the names of birds are alphabetically arranged ; and these, so far 

 as concerns the forms represented in the present Owston collection, are 

 marked with the reference number of each in parenthesis, so that the table 

 may also serve as an index to the contents of this report. The comparatively
