Ridgway's description was based upon 20 specimens, all of which must 

 be considered cotypes. No. 69984 was marked as the type by Richmond 

 and has been designated as such by Grinnell (Univ. California Publ. Zool. 

 32: 113, 1928), but it seems to be simply a lectotype, with no more claim 

 to typeship than any other of the series. 



The fates of the six remaining cotypes are as follows : 



No. 69983, an unsexed adult, and No. 69988, an unsexed immature, were 

 sent to J. H. Gurney on Jan. 12, 1882, and are now in the Castle Museum, 

 Norwich. No. 69990, an immature male, was sent to Osbert Salvin in Aug. 

 1876, and is now in the British Museum. No. 69991, an immature male, 

 went to the Mombusho Museum in Tokyo in 1877 and was destroyed by the 

 great earthquake and fire of 1923. No. 69992, an unsexed adult, should 

 still be in the national collection, but cannot now be found. No. 69996, an 

 unsexed pullus, was sent to von Berlepsch on Sept. 25, 1882, and pre- 

 sumably later entered the Senckenberg Museum at Frankfurt-am-Main, 

 although it could not be found there in 1932 (see Abbott, Condor 35: 11, 

 1933). 



The original label of No. 69980 became separated from the skin at the 

 time of mounting, and the bird was given a new number when dismounted 

 in September 1880.
