1859, p. 13. Progne dominicensis, nobis (nee Gm.)=P. leuco- 

 gastra, Baird, Rev. Adi. B. part i. p. 280. 



The males, as far as my observations go, never have 

 the glossy steel-blue of the back on the throat and chest, 

 thus differing from the true P. dominicensis of the 

 Antilles. 



„ p. 14. Chlorophanes atricapilla, nobis, ?= C. guatemalensis, 

 Scl. The difference is very slight. 



„ p. 19, Sturnella hippocrepis, Wagl. (?) 



I agree with Cabanis in uniting all the numerous 

 species of Sturnella of this form under the old name 

 oiS. ludoviciana. I am quite at a loss to detect the cha- 

 racters by which they are said to be distinguishable. 



„ p. 20. Icterus affinis, Lawr. = /. spurius, L. 



„ p. 119. Thamnophilus melanurus, nobis (nee Gould) = 7^. 

 melanocrissus, Scl. P. Z. S. 1860, p. 252. 



„ p. 122. Contopus borealis, nobis (nee Sw.) = C. pertinax, 

 Cab. et Hein.: Scl. Cat. p. 231. 



„ p. 122. Contopus mesoleucus, Scl. = Tyr annus borealis, 

 Sw. : Scl. Cat. p. 230. 



„ p. 122. Contopus sordidulus, Sc\.= Tyrannula richardsoni, 

 Sw. r. B.-Am. : Scl. Cat. p. 231. * 



„ p. 124. Lipaugus 7'ufescens,Sc]. Probably from Panama. 

 We never met with the species in Guatemala. At 

 Panama it does occur. 



„ p. 124. Chiroxiphia linearis (Bp.). Never from Vera 

 Paz ; the species is peculiar to the Pacific coast-region. 

 The supposed specimens from Vera Paz came through 

 Don Vicente Constancia, whose information respecting 

 localities I have sometimes found incorrect. 



„ p. 125. Nyctidromus americanus (Linn.) ? = N. guianen- 



sis, Gm. Probably the only species of the form. 



The true Caprimulgus americanus, L., founded on C. 



jamaicensis, Briss., is the Siphonorhis americanus, Scl. 



(see Cat. Am. Birds, p. 282).
