114 Mr. 0. Salvin on Mr. Lawrence's 



name must be treated as a synonym of A. plagiata, Schl. In 

 his note on Geotrygon chiriquensis, Mr. Lawrence complains 

 that Mr. Sclater and I misled him into giving a new name to 

 the species, by having wrongly united G. albifacies to G. chiri- 

 quensis (Exot. Orn. t. 39) ; but regretting, as I do, the error we 

 made, I think Mr. Lawrence was in a position to put us right 

 when he had the true G. chiriquensis before him, having indeed 

 the same materials in his hands which viltimately gave us the 

 clue to our error. The anomalous fact of a distinct species 

 occurring in Costa Rica, and intercepting the range of our 

 so-called G. chiriquensis was sufficient to render the reopening 

 of the question a prudent step. 



I now record the additional species, all of which, except nos. 

 7 and 19, have been forwarded to us by Mr. Carmiol since the 

 publication of my former notes : — 



1. Geothlypis poliocephala, Baird, Rev. Am. B. p. 225 : 

 G. aquinoctialis, Scl. & Salv., Ibis, 1860, p. 273. 



— 2. Stelgidopteryx pulvipennis (Scl.), {vide supra). 



3. Calliste FLORIDA, Scl. & Salv., P. Z. S. 1869, p. 416, 

 t. xxviii. 



4. HiEMOPHiLA uuFicAUDA (Bp.)j Scl., Cat. Am. B. p. 118. 

 In a former note on Zonotrichia melanotis, Lawr. (Ibis, 



1868, p. 115), I inadvertently wrote humeralis for ruficauda, 

 certainly intending to say that Z. melanotis appeared to be 

 allied to, or perhaps the same as H. ruficauda. I have now 

 seen both species, and am satisfied they are distinct, though 

 near allies. 



— 5. Cyanocitta ornata (Less.) ; Scl., Cat. Am. B. p. 143. 



— 6. Calocitta FORMOSA (Sw.) ; Scl., Cat. Am. B. p. 145. 

 The acquisition of these two species of Corvida makes a great 



addition to the Bird-fauna of Costa Rica. 



— 7. Thamnophilus immaculatus, Lafr,, R. Z. 184.5, p. 340 : 

 Scl., Cat. Am. B. p. 17^ : Phlogopsis ellisiana, Scl., P. Z. S. 

 1855, p. 109, t. 100, Cat. Am. B. Ap. p. 360 ( ? aut c? juv.).
