1") Everett, in a note to Chnjsococcyx xanthorhynclim , suggests that Hetero- 

 coccyx neglectus (Schleg.) Salvad. Ucc. Born. p. 61, the type of which is in 

 the Leyden Museum, might he a style of C. xanthorhynchus, for which reason 

 he does not enumerate it in his List as a distinct species. Shelley, in his 

 ahove mentioned catalogue, p. 294, adds it. though with a point of interrogation, 

 to the synonymy of Chalcococcyx iasalis. Dr. Finsch, whom I asked to examine 

 the bird in question, writes me that it is really a good species, allied to 

 Prodotiscus regulus Sund. and that Heterococcyx of Salvadori is a valid genus. 

 Shelley entirely forgot to mention the genus in his Catalogue.
