Conirostres. — Most of the North American species of this, 

 which is the t3'pical tribe of insessorial birds, belong to the frm- 

 gillidce, one of the aberrant families. The two normal families 

 also include a tolerable number of species, but the two remaining 

 aberrant families {musophagiclce and huceridte) have no members 

 in North America. Among the fringillidcE we find one alauda, 

 two plectrophmies, onefrbigilluy two linarice, o\ie pi/rrhula, and 

 two loxiae, common to the two countries. In addition to these the 

 alauda calandra of the south of Europe is noted in the Fauna 

 Soreali-Americana as having been taken at Hudson's Bay, but 

 as the only authority is a specimen in the British Museum of 

 not very certain origin, it is omitted in the preceding list. The 

 perfection of ornithological structure is to be found, according 

 to Mr. Swainson, in the corvidce, the typical family of the co?z?- 

 ?-05/re5, or typical tribe of the insessorial or typical order. The 

 raven, which is a typical example of the genus corvus, is common 

 to the four quarters of the world, and most ornithologists con- 

 sider the carrion crow and the magpie of America to be the same 

 with those of Europe. Mr. Audubon, however, describes the 

 former as a peculiar species under the name of americanus, and 

 Mr. Sabine has treated the magpie in a similar manner, though 

 he has not been followed by subsequent writers : — it is certain 

 that he has failed in pointing out any constant or appreciable
