SENEGAL PI APEC. 
Ptilostomus Senegalensis , Swains. 
Glossy black, with transverse linear shades on the tertials ; 
quills and tail light brown, the latter with the feathers 
lanceolate. 
Corvus Senegalensis, And. — Le Pie du Senegal, PI. Enl. 538.

It appears that this singular bird supplies the place 
of our magpie in. the more southern latitudes of 
Africa ; and yet, although its size and general shape 
has some resemblance to that bird, there is no real 
affinity between them. Our magpie, in fact, is only 
a sub-genus of Corvus, as is shown by the formation 
of its hill and nostrils, while this has all the cha- 
racters belonging to the Glaucopina or wattle-birds. 
According to the analysis we have made of this sub- 
family, Ptilostomus is the rasorial genus of the circle, 
being immediately followed by Crypsirina, which, 
with the more typical species*, conducts us at once 
to the genus Glaucopis. It is really extraordinary 
that all the modem ornithologists, who have written 
upon these birds, should have overlooked one of the 
most important parts of their structure : for in none 
* liu/a leucoptera, temnura, leucogastra, sinensis vagabunda, 
and other species placed in the supposed genus Dendrooitta.
