This species is so extremely rare that I have never been able to see a specimen in any collection, nor to learn 
anything respecting it ; but as I am perfectly satisfied of its being a good species, rather than omit it I have 
copied the figure published by Le Vaillant in his Hist. Nat. des Couroucous ; and also the short account lie 
has there given of it. 
“ This species comes from St. Domingo, and is alluded to by Buffon, who seems to have considered it a 
mere local variety of the Couroucou a ventre rouge de la Guyane. But I think that a comparison of our 
figure of this species with those of the species alluded to in its adult, as well as its young state, will convince 
any one of BulFon’s mistake in this respect. 
“ I am not aware whether the individual which forms part of my collection be male or female ; I know, 
however, for certain that it is an adult. It is surprising that M. le Chevalier Lefebvre Deshayes, who has 
given so long an account of this species, should have said nothing upon the differences of the sexes, — a kind 
of information in my opinion which would have been more instructive than what he tells us, when he says, 
that this bird with its beak reduces to powder sound wood when it cannot find worm-eaten wood to de- 
posit its eggs in, which certainly seems like an impossibility. This species is very rare in collections, for I 
have only seen, in addition to the specimen in my own collection, two others in the collections of the late 
Abbe Aubry and Dr. Mauduit. It has never been in the collection of the Paris Museum, although Buffon is 
quite correct in saying that he received a figure and description of it.” 
In the “ Tableau Encyclopedique,” above-quoted, M. Vieillot states that it is found in Mexico, but from my 
own knowledge of the group I am of opinion that he is mistaken on this point, and that he has confounded 
it with a species inhabiting that country. In its affinities it is most nearly allied to the Trog. temnurus ; 
the marking of the wing and other particulars being very similar in both species. 
At Saint Domingo several names are applied to it ; in some of the provinces it is called Calegon rouge, in 
others Dame, or Demoiselle Anglaise ; and also Pie de Montagues, from its continually residing among the 
mountains.
