154 Obituary. [This, 



I will touch on tliis in dealing, elsewhere, with my experi- 

 ments on carnivorous animals. Meantime, I may say that 

 it seems to me to tell against mimicry in relation to the 

 host, but not against mimicry for protection from enemies. 



Finally, we have the Cuckoo as a possible model for 

 mimicry, suggesting that it, too, sometimes possesses 

 nauseousness. I refer to the resemblance between the 

 females of the Emerald Cuckoo and of Campophaga nigra 

 and hartlauhi. It even extends to the bunchy appearance 

 of the rump, noticeable in the field. 1 am aware of the 

 objections to the view that these atid the other resemblances 

 referred to here are real cases of mimicry and, np to a 

 certain point, share in them myself, but I feel that they 

 are probably strongly protective and that the element of 

 real mimicry in them is probably considerable. 



Major Meiklejohn's summary of known fact and of points 

 on which further information is needed is both interesting 

 and likely to be highly useful to investigators. In the one 

 or two places in which the above remarks happen to have 

 overlapped his statement, it has not been done with any 

 idea either of "poaching'" or of criticizing — though I 

 think that the view that the Cuckoo bases its choice on 

 egg-coloration requires careful testing. I have merely felt 

 that it is sometimes suggestive to state things from slightly 

 different standpoints. Elsewhere I have tried to suggest 

 one or two additional points for investigation.
