No. 2. Lanius Cubla. 
This I have no hesitation in considering as the Hottniqua Shrike of 
Dr. Latham, and Le Cubla of Le Vaillant, pi. 12, with which it agrees in 
almost every point, except that the black of the head runs down to the 
beak only in a point on the front, all between the eyes and the nostrils on 
each side being of a dingy white ; this colour also extends higher up the 
back than these authors appear to represent it ; and though the feathers are 
extremely silky and soft in their texture, the white upon them is by no 
means clear or dazzling; but, like the same colour upon the edges of the 
wing coverts, is strongly tinged with . pale brown. I conclude it to be a 
young male, not entirely arrived at his full plumage. 
No. 3. Lanius Ferrugmeiis, Var. 
This, on the whole, I consider only as a further variety of Dr. Latham's 
ferruginous bellied Shrike, as^they perfectly agree in size, length, and in the 
general character of the plumage. In the present specimen, however, the 
head, upper part of the back, and the tail, are black, not brown- black as in 
the other bird ; the scapulars and lower part of the back, with the rump, 
also appear black, but on the feathers being lifted up, each is found to have 
a large white spot towards the end, with a deepish fringe of greyish black ; 
these feathers are of a very light, loose texture, and appear to have an addi- 
tional tuft of a light waving nature, nearly as long as the feather springing 
from the same shaft on its under side. The chin and throat are white^ the rest 
of the under parts cream colour. On the coverts of the wings is a length- 
ened spot of white parallel to the edge ; the quills are plain black ; the 
legs are strong, and of a blueish lead colour ; claws dark, hind claw crooked 
and strong; the bill, from the gape to the tip, is not quite an inch long, 
rather compressed ; the tail is a little rounded in shape. 
No. 4. Lanius humeralis, or White shouldered Shrike. 
The bill in this bird is three quarters of an inch from the tip to the gape, 
and not quite half an inch to the front ; the depth from the upper to the 
under edge of the bill is about one quarter of an inch. The general colour 
of the plumage appears nearly to agree with No. 8 ; but the black h
