Now Colluricincla woodwardi Hartert, 1905 . See Mayr, 1967: 14 , Schodde and Mason, 1999: 463 , and Boles, 2007: 432–433 . HOLOTYPE : AMNH 656877 , immature male, collected at McArthur Station , 16.27S , 136.06E ( Storr, 1977:110 ), McArthur River , Northern Territory , Australia , on 5 September 1913 , by H.G. Barnard. From the Mathews Collection via the Rothschild Collection. COMMENTS: In the original description, Mathews gave the place and date of collection of the type as McArthur River on 5 September 1913 . The above specimen is the only such specimen that came to AMNH and is the holotype . It bears a Mathews Collec- tion label, marked ‘‘ Type’ ’ by Mathews and a Rothschild type label. In addition there is an H.L. White Collection label (no. 145), filled in by Barnard , a Rothschild Collection label printed ‘‘ Ex. coll. G.M. Mathews’ ’ and a ‘‘ Figured’ ’ label, indicating that it was illustrated in Mathews (1923a , pl. 480, opp. p. 302, text p. 302), where it is confirmed as the type of didimus . The wing measurement of 114 mm given for this specimen is correct, but the specimen is a very worn juvenile. There is one paratype : AMNH 656878 , female, collected on the McArthur River , on 29 August 1913 , by Barnard and also from the H.L. White Collection (no. 145). These specimens were probably acquired from White during Mathews’ 1914 trip to Australia ; neither was cataloged by Mathews. [ Colluricincla woodwardi assimilis Mathews ] Mathews (1914: 100) described assimilis from ‘‘ Northern Territory [East]’’ and designated as type a specimen collected at Napier Broome Bay, North-west Australia on 20 July 1910 . There is no specimen of Colluricincla in AMNH collected on 20 July 1910 from either Northern Territory or Western Australia .
