xi INTRODUCTION. 
has been published by Professor Bocage, wherein will be found a 
full account of Senor Anchieta’s labours. We cannot too warmly 
express our thanks to our excellent friend above mentioned, who 
has sent us over from Lisbon many rare species to aid us in the 
preparation of the present work. 
Finally, we have deemed it of some advantage to future students 
of South African ornithology to give a list of the principal papers 
published in the Ibis which relate, more or less, to the subject of 
the present book; and we only regret that space has not allowed 
us to give more than the present slight sketch of the labours of 
our predecessors in the field of South African ornithology.
