X 1859, p. 13. Progne dominicensis, nobis (nec Gm.) = P. leuco- 
gastra, Baird, Rev. Am. 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 
of S. 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. = I. spurius , L. 
p. 119.* Thamnophilus melanurus , nobis (nec Gould) = T. 
melanocrissus, Scl. P. Z. S. 1860, p. 252. 
p. 122. Contopus borealis , nobis (nec Sw.) = C. pertinax, 
Cab. et Hein.: Scl. Cat. p. 231. 
p. 122. Contopus mesoleucus , Scl. = Tyrannus borealis , 
Sw. : Scl. Cat. p. 230. 
p. 122. Contopus sordidulus , Scl.= Tyrannula richardsoni, 
Sw. P. B.-Am. : Scl. Cat. p. 231. 
,, p. 124. Lipaugus rufescens , Scl. 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. 
Z „ p. 125. Nyctidromus americanus (Linn.) ‘I = N. guianen- 
sis , Gm. Probably the only species of the form. 
The true Caprimulgus americanus , L., founded on C, 
jamaicensis , Briss., is the Sip honor his americanus, Scl. 
(see Cat. Am. Birds, p. 282).
