One specimen, agreeing with a Guiana specimen in the Bremen 
collection. 
90. PreroGLossus ARAGARI, L.; Scl. Cat. p. 325. 
One specimen, similar to another from Guiana. 
Dr. Léotaud does not notice this species from Trinidad. The P. 
wiedii, Sturm, is very closely allied, and can be distinguished only 
by a slight difference in the markings on the upper mandible, as has 
been pointed out very minutely by Mr. Sturm (Monogr. Ramph. 
4 Heft). P. aragari is not confined in its distribution to Guiana 
and Northern Brazil; for Prof. Burmeister (ii. p. 208) got the true 
P. aracari in Minas Geraés. The black stripe along the culmen 
varies in extent; in our Guiana specimen it ts 53'” broad, in the 
Trinidad one 53'", in the Brazil specimen (P. wiedii) 4'". The size 
is also variable.

Dr. Cabanis has separated a conspecies from Venezuela (P. for- 
mosus, Journ. f. Orn. 1862, p. 332), said to be different from 
wiedii in having the chin and throat dark red-brown, the black stripe 
along the culmen narrower, and in its larger size (the measurements 
are, unfortunately, not noticed). I doubt whether these differences, 
based on a single specimen, are of specific value; the dark reddish- 
brown tinge on the ear-coverts, on the chin and throat, is also visible 
in our Brazilian specimen, and, as remarked by the Prince of Wied, 
is peculiar to the female.
