Discussion. 



The President (Prof. Sollas) expressed his sense of the great 

 amount of labour which had been expended in the investigation of 

 this interesting genus. It was fortunate that the study of Palaeo- 

 zoic Gasteropods, which made great demands on the skill of the 

 palaeontologist, was in hands so competent as those of the 

 Authoress.
