pelled to make. As a whole, they are distinguished from 
all other birds by their short, 
finch-like bill, the commissure 
of which is always arched, and 
sometimes sinuated,like that of 
a Frinyilla. The genus Glnu- 
copis, which is the pre-eminent 
type, shows us this structure in 
great perfection add- 
ed to another which is equally 
indicative of the rasorial struc- 
ture, that is, strong walking 
legs. Following this we have the Senegal Piapec, form- 
ing our genus /'/(Vos-towms*, intimately related, accord- 
ing to M. Temminck, with his Comm (jymnocephalus t, 
upon this authority we conjecture the last mentioned 
bird may prove the grallatorial type. The singular genus 
Brachy stoma, from New Holland, long since noticed by 
us, as connecting this group with the jays, leads at once 
to the finch crows of India, all of which, in our opinion, 
are merely variations of that type named Crypsirina by 
M. Vieillot.^ Some of these, from their close resemblance 
to Glaucopis, have actually been placed in that genus by 
M. Temminck, who seems to have overlooked the entirely 
tlilferent structure of their legs. The circle is thus 
closed, and we find that these five types represent the 
primary divisions of the whole class. 
(112.) The following genera we exclude from this 
family, where they have been placed by some authors : — 
Epimachus, as belonging to the suctorial birds; Coracins. 
as being completely united toEurystomus by two species 
now before us, the latter being well-known as a fissiros- 
tral group; and Gmewfo, as unitetl'to among the 
fiturnida:. The Paradise birds {Paradiseada:'), hitherto 
arranged with the crows, form the most aberrant group 
of our Tonuirostres, and are placed between the hoopoes 
and the honcysuckers.
