understanding of the various allied forms can only be effected liv a comparison of 

 Lafresnayes and Des Murs' ty])es, and with a larger material than is available at 

 present in any one museum. Hartert has compared most of the material in the 

 British Museum, and he has come to the conclusion that Dendrornis guttafoides 

 Sclater (nee Lafr !) Cat. B. Brit. Mtis. XV., p. 128, from Cayenne and British 

 Guiana, is the same as our i). r.sororia; while the real Deiu/roriuH Q'' yasica"') 

 quttatoides Lafr., Ri'c. et Mag. Zool. iSoU, p. 387 (ex Colombia), is quite a different 

 bird, with a much more rufous underside. The description of Xasica beauperthuysii 

 Puch. et Lafr., Rec. I'.t Mag. Zool. 1850, p. 419 (ex Peru), also does not suit our 

 sororia. {N.bi'aupertkui/.^ii is given by Sclater \_Cat. B., XV'., p. 133] as a synonym 

 o{ Dendrornis stisurran.i, but this can hardly be correct I) Dendrornis eijtoni Sel. 

 is also somewhat similar to our sororia, but the apparently entirely black bill, 

 whiter throat and pectoral spots distinguish it well enough. The types of 

 Dendrornis poh/sticta have also a much whiter throat, more blackish edges to the 

 feathers of the jugulum and breast, and a shorter bill ; but Hartert has the 

 impression that they are not very adult, and he thinks that it is not quite 

 impossible that they are the young of our sororia (= guttatoides Scl. nee Lafr. !), 

 and that one of the skins in the British Museum supposed to be poh/sticta is 

 certainly indistinguishable from Sclater's " guttatoides" {fvoxn the same locality 1) 

 and our sororia. More material must be examined.
