11(3 ItEVlEWS AND NOTICES. 



Giant Eagle Owl were all found nesting. There is a good 

 paper on '' Bird-Farasites and Bird-Phylogeny " by 

 Laancelot Harrison, B.Sc. He discusses the relations and 

 biology of the Mallophaga group of insects (biting lice) 

 which infest birds. 



Mr. C. F. M. Svvynnerton, F.L.S., F.E.S., etc., gives an 

 interesting paper on the coloration of the mouths and eggs 

 of birds. No. 1, the Mouths of Birds, is illustrated by a 

 double coloured [)late of the insides of certain birds' mouths. 

 These have in many cases striking coloration. 



The July number contains Part 2 of Dr. V. G. L. van 

 Someren's paper on the Birds of Uganda and British East 

 Africa, with plates 8 to 13. Plate 10 represents several 

 exam})les of Corvus scapulatus on a rocky^ hillside. 



There is a paper l)y Dr. A. G. Butler on " The assumption 

 of Summer Plumage in L^^^romelana oryx." Dr. Butler 

 argues, from a specimen in his aviary, that the summer 

 plumage is assumed l)y a gradual change in the coloration of 

 the feathers, and not by a partial or complete moult. 



The October number contains Part 2 of Swynnerton's 

 paper " On the Coloration of Birds' Eggs." This is illus- 

 trated by a coloured plate of 25 eggs. The author carried 

 out certain experiments, which he describes, showing that 

 certain animals had certain preferences. He deals with the 

 theory of coloration of eggs : their conspicuousness or 

 otherwise, variability, etc. 



Avicultural Magazine. Vol. VII.. Nos. 1-12, Novemljcr 

 1915 to October 191G. 



It is proposed to notice only articles of S. African or 

 general interest. The November number contains a short 

 account of the breeding and rearing of a hybrid weaver-bird 

 — a cross between a male Hyphantornis cucullata and a 

 female H. spilonotus. Mr. Albert Pam gives us some 

 notes on the transi)ort of birds. The January 191(3 number 

 opens with an article on the genus Zosterops by Dr. A. G. 

 Butler, which is illustrated by some pretty photographs of 

 Zosterops capensis, the Ca[)e White-eye; while Mr. 

 F. E. Blaauw writes on " Sunbirds in their native haunts"
