1. Micrastur gilvicollis. — Sparvius gil 'vicollis, Vieill. ; M. 

 concentricus, Auct. 



A fine specimen in M. Verreaux's Mexican collection agrees per- 

 fectly with Mr. Cassin's plate and description of M. guerilla (Jonrn. 

 Acad. Philad. ii. p. 295. pi. 40), and I have no doubt is the same bird. 

 M. Jules Verreaux writes to me that he considered this at first to 

 be the young of M. concentricus, though he was afterwards inclined 

 to alter his opinion. Mr. George Gray and Mr. J. H. Gurney, 

 however, both regard this example as referable to an immature 

 stage of M. concentricus, and such will probably be found eventually 

 to be the case. The specimen in question has been selected by Mr. 

 Gurney for the Norwich Museum. 



2. Ciccaba huhula (Daud.) ; Bp. Consp. i. p. 43? 



An example, which I am unable to refer otherwise than to this 

 species, has the white feather-margins on the upper surface nearly 

 evanescent, leaving the back nearly uniform slaty black. M. Jules 

 Verreaux, who has examined a second example, considers it as a de- 

 cidedly different species, probably undescribed ; but I should wish 

 to consult a larger series of specimens before determining as new 

 a bird of this difficult group. 



3. Scops flammeola, Kaup. — Strix fiammeola, Licht. in Mus. 

 Berol. ; Ephialtes flammeola, Licht. Nomencl. p. 7. 



This diminutive species of Scops is described by Kaup in a Mo- 

 nograph of Strigidse, which will shortly appear in the Society's 

 Transactions. A single specimen obtained by M. Salle from the 

 vicinity of Jalapa is in the late Prince Bonaparte's collection. 



4. Trogon massen^e, Gould, Mon. Trog. pi. 16. 



M. Verreaux's collection embraces fine examples (S et ?) of this 

 splendid species. 



5. Dendrocolaptes sancti thomje. — Dendrocops sancti 

 thomce, Lafr. Rev. et Mag. de Zool. 1852, p. 466. 



In M. Verreaux's collection is a fine specimen of this bird, for 

 which I believe M. de Lafresnaye's name is unfortunately chosen, 

 as the present example is from Southern Mexico, and I possess an- 

 other from Honduras. Besides, I recognize the same species among 

 some drawings by Mr. Bell, of birds obtained on the coast of Mos- 

 quitia. I therefore doubt whether it really occurs in the island of 

 St. Thomas, and consider S. Mexico and Central America as its true 

 habitat. 



6. Cyphorinus prostheleucus. — Scytalopus prostheleucus, 

 Scl. P. Z. S. 1856, p. 290. 



I have already made some remarks on this species, which is by 

 no means a Scytalopus, but a Cyphorinus, closely allied, if not iden- 

 tical, with Cassin's C. leucostictus. See antea, p. 63.
