(3) Dendrorxis lawrencii, Ridgw. Pr. U.S. Nat. Mus. 

 1887, p. 509 (Panama). 



(4) Dendrornis lawrencii costaricensis, Ridgw. op. 

 cit. p. 510 (Costa Rica). 



I am sorry to be obliged to differ with Mr. Ridgway, but 

 I am still of opinion that the Panama bird^ which he now 

 proposes to call D. lawrencii, and its Costa- Rioan represen- 

 tive cannot be separated from D. susurrans. I have lately 

 had a large series before me from Honduras, Costa Rica, 

 Veragua, Panama, Santa Marta, Venezuela, Trinidad, and 

 Tobago — between thirty and forty specimens. There is 

 much individual variation ; but in the Dendrocolaptinae such 

 is usually the case, and some of the Panama skins of this 

 bird are quite like the Tobago birds, upon which the species 

 was founded. 



Mr. Lawrence has called this bird D. pardalotus and D. 

 guttata; and if his D. nana is different, I am not acquainted 

 with it. See remarks by Mr. Salvia and myself upon this 

 subject, P. Z. S. 1870, p. 839. 



(5) PicoLAPTEs GRACILIS, Ridgw. (Costa Rica). 



This species is quite new to me, and different from any- 

 thing I know. It is remarkable for its short bill and small 

 size. 



~ (6) Dendrocincla rufo-olivacea, Ridgw. Pr. U.S. Nat. 

 Mus. 1887, p. 493. 



This is the bird I call D. fuliginosa (Vieill.) — a species not 

 identified by Mr. Ridgway in his monograph. I have speci- 

 mens from British Guiana [Whitehj) and Para {Wallace), 

 and there are others in the Salvin-Godman collection. 



- (7) Dendrocincla castanoptera, Ridgw. op. cit. p. 494. 

 I have examples of the same bird from Surinam {Bartlett)
