1887.] MB. R.TRIMEN ON LANIARIUS ATROCROCEUS, 'Ad/ 



of damaging the L. atrocroceus. At length (several interlacing 

 branches partly screening the birds) he ventured a shot, and had 

 the satisfaction of securing the prize in excellent condition. The 

 L. atrocoecineus still kept in close proximity, apparently looking out 

 for his opponent. Mr. Eriksson shot this specimen also, iu order 

 to make sure of its being a male. 



'• This discovery of a second example of L. atwcroceus in a locality 

 so little removed from that of the first is of much interest : and in 

 the complete absence of any record of so conspicuous and striking a 

 bird from any other part of Africa, teivds strongly to localize the 

 race or variety within very narrow limits. [The sex of Dr. Brad- 

 shaw's specimen vras not ascertained.] 



" The case of this Laniarius seems much to resemble those of the 

 singular form of Cheetah {Felts lanea of Sclater), of which only five 

 specimens are known, all from the very limited area of Nel's Point, 

 in the Beaufort District of the Cape Colony, and the equally aberrant 

 Leopard {F. pardus, L., var. melas; see Trimen, P. Z'S. 1883, 

 p. 535, and Giinther, P. Z. S. 1885, pi. xvi. p. 243), of which only 

 three examples aie known, from the neighbourhood of the Koonap 

 Eiver, in the Fort-Beaufort District on the eastern side of the Cape 

 Colony. It is very noticeable that, in all three cases, the abnormal 

 form does not replace the normal one to which it is so nearly re- 

 lated, but occurs in the midst of the latter, quite isolated, yet ap- 

 pearing to maintain and perpetuate (albeit in but very few individuals) 

 its peculiarities of colouring or of pattern."
