belonging to the Genera Phytotoma, Indicator, Cursorius, &c. 87 
which it is certainly closely allied, than the superficial characters 
already given of it afford me. I have, however, subjoined a 
detailed account of the chief characters of the bird in the above 
description, in order that those ornithologists, who may have 
the good fortune of being able to compare the species of the 
true PAytotoma with it, may ascertain how far the birds agree. 
I have to add, when alluding to the extraordinary dimensions of 
the bill of the species, that the jaw-bones extend in width even 
further than the beak itself; the space between them being 4*;ths 
of an inch, while that between the gnathidia of the lower man- 
dible is but 4z,ths. 
The greatest breadth of the skull above is 3ths of an inch.

public mark of approbation, and whose long continued friend- 
ship demands from me this private tribute of esteem.
