Dr. Leotaud's 'Birds of Trinidad.' 107 



Trinidadian avifauna, and show its complete identity with that of 

 Venezuela. 



Having said thus much upon Dr. Leotaud's work, I will 

 conclude with a few notes upon such points as seem to require 

 special notice on turning over the pages of his " partie descrip- 

 tive." 



Cymindis pucherani (p. 40) is a supposed new species of this 

 genus, founded upon a single specimen. Can it possibly be 

 Urubitinga anthracina or U. schistacea ? 



Caprimulgus albicollis (p. 72) is evidently a Nyciidromus, and 

 should be placed in that genus — although nothing is said of the 

 long naked tarsi, which render this form so easily distinguish- 

 able from Caprimulgus. 



Chordiles ininur (p. 76) is no doubt the South American C. 

 acutipennis, not the C. minor of Jamaica. {Cf. P. Z. S, 1866, 

 pp. 133-134.) 



Hirnndo rutila (p. 87) is a Chcetura or Acanthylis (according 

 to Dr. Leotaud^s nomenclature) belonging to the family Cypse- 

 lidce. Has Dr. Leotaud ever obtained authentic examples of 

 this species in Trinidad (he does not say so positively) ? or does 

 he put it into his list upon the authority of Robin and older 

 writers ? More recent authorities doubt its occurrence in this 

 locality. {Cf. P. Z. S. 1865, p. 613.) 



Cotyle uropyijialis, Lawrence (p. 94), ought probably to be C. 

 ruficollis (Vieill.), the former being the western local form, and 

 the latter the eastern representative of the species. 



Dendrocolaptes altirostris (p. 166) is a new species of this dif- 

 ficult group, near to D. picus, but was considered by the late 

 naturalist Lafresnaye, to whom it was submitted, to be specifi- 

 cally distinct. 



Trichas velatus (p. 183) should be Trichas or rather Geo- 

 thlypis cequinoctialis, G. velata being the Brazilian form of the 

 species. {Cf. Cat. Am. B. p. 27.) 



The Tyrannus verticalis sive vociferans of Dr. Leotaud (p. 213) 

 is, no doubt, the common T. melanchoUcus, or its barely distin- 

 guishable northern representative T. satrapa. Neither T. verti- 

 calis nor T. vociferans (which are quite different species) range 

 so far south.
