77. North on the Nests and Eggs of Australian Birds. 
[Nests and Eggs of Birds found breeding in Australia and Tasmania. 
By Alfred J. North, C.M.Z.S. Vol. iii. Part 1.* Sydney, 1911.] 
We have received another part of this valuable work. In 
it the account of the Australian Cuckoos is finished and 
that of the Parrots is commenced. Many interesting parti¬ 
culars are given concerning the breeding-habits of the 
Australian Cuckoos. It appears to be now quite settled 
that Cucu’us inornatus in some cases feeds its own young. 
A startling picture, taken from a photograph, is given of 
“Fred” (an Australian aboriginal) taking a nest of the 
Blue-tailed Lorrikeet. 
78. Percival on European Migrants in British East Africa. 
[European Migrants in British East Africa. By A. B. Percival. 
Journ. E. Afr. Nat. Hist. Soc. vol. i. p. 101 (1911).] 
This is a nicely written paper upon a very interesting 
subject, and Mr. Percival deserves our thanks for calling 
attention to it. British East Africa, he reminds us, is half¬ 
way between the winter and summer residences of many 
European migrants, and a series of dates when birds pass 
through it on their southern journey, and again on their 
return trip, would be of great importance. Mr. Percival, 
whose business it is to wander about the country as Game- 
warden, has excellent opportunities for occasionally turning 
his attention to Birds, and invites his brother-members of 
the Natural History Society of East Africa and Uganda to 
aid him in this task. We trust that they will follow his 
excellent advice. 
Mr. William Sclater read a paper on South-African 
migration before the British Association in 1905, and 
Mr. Percival copies Mr, Sclater’s list of migrants and 
makes remarks on it. At least ninety species of the South- 
African Avifauna are known to go north every year to breed 
in Northern Europe and Asia, and must necessarily pass 
through Africa on their journey. It is probable that a large
