Dr. J. C. Willis, F.E.S., F.L.S., followed with his lecture on 

 "Endemic Genera in relation to others," showing numerous 

 lantern-slides in elucidation of his remarks, abstracted as 

 follows : — 



In a paper of 1916 the deduction was made that, in general, 

 endemic species of small area were not relics, but species in the 

 early stages of spreading, and much evidence has since been 

 brought up to show the truth of this. It is now proposed to 

 extend this deduction to endemic genera, and to endeavour to 

 show that there is no appreciable difference between a local 

 endemic and an allied genus of wide distribution (of course work- 

 ing always with groups of genera) other than age. 



The case of the endemic genera of islands is taken for detailed 

 illustration, and a prediction is made about the general composi- 

 tion of the list of such genera. In the first place, it is clear that 

 such a prediction can only hope to be successful if the islands 

 obtained the bulk of their floras by means of land communica- 

 tions ; if their floras be really casual oversea migrants, one can 

 hardly hope ever to predict it.
