There are still several points in Mr. Crombie's paper of minor

Note on the Probable Migration of Pingutculaj/fandi/lora through 





the Agency of Birds. By Prof. Allmax, M.D., LL.D., 

 F.K.S., President Linn. Soc. 







[Read June 6, 1878.] 



In the month of June 1877 I received from the co. Cork a consi- 

 derable number of specimens ofPinguicula grandiflora, and planted 



them round the margin of a small pond at Parkstone in Dorset- 

 shire. 



They took admirably to their new locality, and for some months 

 continued to flourish ; but towards the end of autumn I was dis- 

 appointed at finding that they began to disappear, and before 

 winter was well advanced a large proportion of my plants had 

 completely vanished. 



A conversation with Prof. Thiselton Dyer led me to suspect 

 that birds were the depredators ; and that in this suspicion I did 

 no injustice to the birds, became sufficiently obvious when a 

 sudden visit to the pond would startle a Blackbird or Thrush from 

 his occupation among the surrounding marsh-plants. On such 

 occasions recent marks of beaks were visible in the peat, and 

 sometimes a recently eradicated Pinguicula might be seen lying on 

 the ground. 



That the birds actually made away with the plants and did not 

 confine themselves to a search for worms which might be concealed 

 among their roots, may be concluded from the actual disappear- 

 ance of most of the uprooted plants. It was chiefly after the 

 plants had passed into the state of bulb-like buds, in which they 

 continue during the winter, that they became liable to attack. 



One fine patch, however, which had been partially protected by 

 surrounding it with branches of trees, escaped destruction and 

 threw up in abundance during the spring its beautiful blue 

 flowers. 



But what especially surprised me was the fact that during 

 the last spring, at a distance of nearly a hundred yards from
