Now Orthotomus sericeus rubicundulus Chasen and Kloss, 1931 . See Smythies, 2000: 532–533 , and del Hoyo et al., 2006: 425 . HOLOTYPE : AMNH 592445 , adult male, collected on Serasan Island ( 5 Sirhassen Island ), 02.30N , 109.03E ( USBGN , 1982a), South Natuna Islands , Indonesia , on 23 September 1893 , by Alfred Everett. From the Rothschild Collection. COMMENTS : In the original description, Chasen and Kloss designated as type an adult male with wing measuring 55 mm . They had in their type series four specimens of this form, including the holotype , which they had borrowed from Rothschild. They labeled each of these specimens with a long narrow label on which is typed ‘‘ Orthotomus ruficeps rubicundulus Chas. & Kloss’’, with AMNH 592445 being additionally marked ‘‘Type’’. The wing of this specimen measures 55 mm . The three paratypes are AMNH 592447, adult male with wing 54 mm , AMNH 592448 and 592449, females with wings measuring 50 and 53 mm , respectively, all from Sirhassen Island, collected by Everett on 23 September 1893 . A fifth specimen, AMNH 592446, adult male, was apparently not borrowed and is not a paratype . This form was described too late to have been included in any of Hartert’s lists of Rothschild types, and the holotype bears only an AMNH type label.
