certain amount of give-and-take, or reciprocal mimicry, seems 

 to have occurred not only between the Heliconii and the 

 Pierines, but also between the Pierines and the Pairilio. 



Dr. Dixey concluded by urging the importance of accurate 

 observations in the field, especially as regards the habits, 

 postures, modes and times of flight, prevalence, seasonal 

 occurrence and exact distribution of all forms associated in 

 mimetic relations. Only by such means, in conjunction with 

 experiments conducted in the midst of their natural surround- 

 ings, could the suggested explanations of these complex 

 phenomena be satisfactorily and finally tested.* • 



Prof. Poulton expressed his gratification with the paper, 

 and at the fact that the Hope Collection under his charge 

 had afforded material for the work. He thought the result 

 of the paper was to extend the theory of Fritz Miiller over 

 some of the ground hitherto believed to be covered by the 

 theory of Bates. Mr. Blandford, Mr. Tutt, and Prof. Meldola 

 contipued the discussion.
