Corvus macrorhynchus  [sic] osai Ogawa

Corvus macrorhynchus  [sic] osai Ogawa, 1905: 196 (Okinawashima, Ishigaki, Kohama, Iriomote, Shinjoshima, and Kuroshima).

Now Corvus macrorhynchos osai Ogawa, 1905  . See Hartert, 1919: 126; Blake and Vaurie, 1962: 273; Dickinson et al., 2004c: 95–102; 2004b: 124; Morioka et al., 2005: 100; and dos Anjos, 2009: 631.

LECTOTYPE: AMNH 674344View Materials, adult male, collected on Kohama-jima (not Kobamashima), Ryu Kyu Islands , Japan, on 26 July 1904, by collectors for Alan Owston (no. 1647). From the Rothschild Collection. 

COMMENTS: Ogawa (1905) studied this collection made by Owston’s collectors in the Ryu Kyu Islands in 1904 prior to the purchase of selected specimens by Rothschild. Ogawa did not designate a type in the original description but charted the measurements of his 15 specimens, each of which bears a collector’s number, from the six islands listed above. Hartert (1919: 126), by giving the collector’s number ‘‘1647’’ of the type, designated it the lectotype; the number used by Ogawa was the same in this case. It also bears a Rothschild type label. Morioka et al. (2005: 100) commented on the frequent misspelling of this type locality.

Specimens purchased from Owston routinely bear two Owston labels, one in Japanese and one in English. It is difficult to be certain of the paralectotypes in the type series of osai because the collector’s number used by Ogawa in his chart were written in red pencil on the Japanese labels and this has faded over time so as to be almost unread- able. The following specimens are definite paralectotypes: Kuroshima, AMNH 674337View Materials (1648 on English label, same no. used by Ogawa), female, 12 July 1904. Ishigaki , AMNH 674338View Materials (1655, 1580?), male, 5 June 1904  ; AMNH 674339View Materials (1657, 1581), female, 26 May 1904  ; AMNH 674340View Materials (1658 K, 1261), male, 29 May 1904  ; AMNH 674341View Materials (1654, 1587), male, 26 May 1904  ; AMNH 674342View Materials (1658, 1584), female, 26 May 1904  ; AMNH 674343View Materials (1656, 1582), female, 26 May 1904. Arugusukujima, AMNH 674345View Materials (1646, also used by Ogawa), male, 15 July 1904 (Ogawa called this locality Shinojoshima). The following two specimens may also be paralectotypes: Iriomote , AMNH 674335View Materials (1652, 1578), male immature, AMNH 674336View Materials (1653, 1579), female immature, 25 June 1904  ; the two specimens listed as immature by Ogawa are listed under 1578 and 1579, but the sexes are reversed and the date is given as 26 June 1904. Morioka et al. (2005: 100) commented on the frequent discrepancies between what is written in Ogawa’s charts and the dates on specimens. Some of the specimens listed as from Okinawa (above, under connectens) may be specimens that Ogawa identified as osai, but I was unable to read the red pencil numbers on any of them.
