Mr. G. A. K. Marshall on 



undoubted defence against baboons as it was against the 

 kestrels (pp. 842-3). Hence the small and medium-sized 

 species were eaten somewhat freely, altliough with evidence 

 from time to time that the acid was disliked, and, on the 

 other hand, a large species with a gieater amount of 

 secretion was avoided, and evidently recognized at sight. 

 Another one being seized, discharged its secretion into the 

 baboon's mouth with immense effect. When however it 

 was killed and offered piecemeal, all the parts except those 

 which contained tlie acid were eaten by the other baboon. 

 If we allow for the fact that Garahid/v, attacked under 

 natural conditions, have a much larger supply of the acid, 

 we must admit that they possess a very powerful defence, 

 and that the meaning of the chief quality which under- 

 lies the aposematic appearance of the large species is 

 tolerably clear.
