Genus V. ENNEOCTONUS. 
Type. 
. Enneoctonus, Boie, Isis, 1826, p.973. . . . . . . . H#.collurio. 
This genus has for its type H. collurio, the Red-backed Shrike, which 
migrates from the Palaearctic Region south through eastern and southern 
Africa. It also includes a closely allied resident African form which, as 
is so often the case, has a more rounded wing than the migratory species. 
The members of this genus have the mantle and scapulars rufous, and in 
the adult males the crown and nape is grey. They differ from the females, 
which rather resemble the young birds and have a somewhat barred plumage. 
In all structural characters they resemble Lantus.
