XV. — Descripfion of a neir Species of Bush-Shrike from the 

 Kmjsna District of Cape Colony. By W. L. Sclater, 

 M.A., F. Z.S.J Director of the South-Arri(\in Museum. 



(Plate VI.) 



Lamarius MARAisr, sp. iiov. (Plate VI.) 



Head and back bluish grey, slightly streaked with green ; 

 back and wings dull green, brightest on the rump and upper 

 tail-coverts; a few of the outer wing-coverts tipped with 

 dull white; wing-quills dusky, edged along the outer web 

 with green, the inner edges of all except the first two pale 

 yellow ; tail-quills dull green, the inner webs and tips of all 

 but the two central edged with pale yellow ; eye-coverts 

 greyish. Beneath dull whitish, the neck and breast with 

 narrow, rather irregular, fine bars of greyish black, and 

 slightly tinged with yellow ; thighs greenish ; abdomen and 

 under tail-coverts pure white ; edge of the wing, axillaries, 

 and under wing-coverts bright lemon-yellow. Iris reddish 

 brown ; bill dark horn, base of lower mandible light horn ; 

 tarsi bluish slate. Length of skin about 7'5 inches, wing 

 3*25, tail 3'5, culmen 60, tarsus 0"92. 



The female resembles the male, but there is not quite so 

 much yellow about the breast, and it is slightly smaller. 

 Wing 3- 10 inches, tail 3*20, tarsus 0-90. 



Mr. Marais, after whom I have named this species, sent 

 me the first example of it two years ago, but I originally 

 thought that it must be a young specimen of L. rnbi- 

 (jinosHS. He, however, stated that his specimens were 

 adult birds, and he has since bhuL a good many more 

 examples.
