GLAUCOPINE. — O7 
pelled to make. Asa Kiger 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 Fringilla. The genus Glau- 
copis, which is the pre-eminent 
type, shows us this structure in 
great perfection (fig.152.), add- 
ed to another which is equally 
indicative of the rasorial struc- 
ture, that is, strong walking 
legs. ae rah we have the Senegal Piapec, form- 
ing our genus Ptilostomus*, intimately related, accord- 
ing to M. Temminck, with his Corvus gymnocephatus ‘, 
upon this authority we conjecture the last mentioned 
bird may prove the grallatortal type. The singular genus 
Brachystoma, 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 cf 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 
different 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; Coracias. 
as being completely united toLurystomus by two species 
now before us, the latter being well-known as a fissiros- 
tral group; and Gracula, as united to Pastor among the 
Sturnide. The Paradise birds (Paradiseade), hitherto 
arranged with the crows, form the most aberrant group 
of our Tenuirostres, and are placed between the hoopoes 
and the honeysuckers.

¢ As the name of Crypsirina has the priority over that of Dendrosttta, we 
have considered it but just to adopt the first, aithough given to an aberrant 
species (C. temia) which connects this group with Piilostomus.
