P. 8. The name Asio, Briss., 1760, should supersede Otus, Cuv., 

 1799, and the type will then stand as Asio otus (Lin.). 



The genus Glaucidium belongs to the subfamily Surnlna. 



P. 10. The name cUmacteris, applied to the type of Scotornis, is, 

 I believe, a mistake for clvnacurus. 



P. 12. Erolla, Less., 1831, should give way to Peltops, Wagl., in 

 Oken's ' Isis,' 1829, 



P. 13. In my former criticism on the use of the word Capita I was 

 misled by its erroneous application in Mr. Gray's first edition to the 

 Bucco tamatia of Gmehn. Mr. Gray has now cleared the difficulty 

 by showing that Capita and its synonym Nyctactes are equivalents 

 of Micropogon, Tern., and he has therefore given a new name, Chau- 

 nornis, to B. tamatia, Gm. In a supplementary note, p. 102, Mr. 

 Gray points out that this genus ought in strictness to bear the name 

 of Bucco, Lin., as the only species of Bucco mentioned by Linnaeus 

 belongs to this group. There is indeed no denying that modern 

 authors have departed from the original type of Bucco, Lin., in re- 

 stricting that name to the East Indian Barbets ; but this application 

 of the term (though incorrect) is now so universally adopted, that I 

 decidedly think it has acquired a prescriptive right which it would 

 be very injudicious to set aside. 



P. 18. Heliothryx should be written Heliothrix. 



P. 20. It appears from Cuvier's ' Reg. Anim.' that the Merops 

 moluccensis, Gm., is the type of Commerson's genus P/iiledon, and 

 that name is long anterior to Philemon, Vieill. 



P. 23. Dendroina, Sw., cannot be synonymous with Diglossa, 

 Wagl., as it is described by Swainson with the margins of the beak 

 entire. Dendroma appears to me to be equivalent to Philydor, Spix, 

 and to include his three species superciliaris, albogularis, and rufi- 

 collis. 



P. 24. The earliest specific name of Xiphorhynchus procurvus 

 seems to be trochilirostris, Licht., and that of Sittusomus sylviellus 

 is erithacus, Licht. 



P. 2G. Thriothonts should be written Thryothonis (from Opvor, a 

 reed, dopew, to leap). 



Thryothorus arundinaceus , Vieill., should be called T. ludovicianus 

 (Lath.). 



According to my obsen'ations, the Edela ruficeps. Less. (Ortho- 

 tomus edela, Tem., P. C. 599. f. 2.), is the sam.e as Motaciila sepium 

 of Rafl[les, but is not the Orthotomus sepium of Horsfield. 



P. 28. The earliest binomial specific name of Locustella is rayi, 

 Gould. It is a misapprehension of Ray's meaning to call the bird 

 Locustella avicula, Ray. He uses the word avicula not as being less 

 general than Locustella, but more so. He intended to say, " a small 

 bird called Locustella," and not " the species of Locustella called avi- 

 cula," which would be his meaning if avicula were a specific name. 



The genu?, Erythropygia, Smith, ought, I think, to be .separated from 

 Aedoti, Boie, notwithstanding the similarity of plumage. Erythropygia 

 is a South African group connecting Cossypka, Vig., with Sudicola. 

 while Aedon is an European genus near Acroccphalus.
