A particularly fine series of the genus Cataiilus was shewn by Messrs. J. Cosmo 

 Melvill, Ed. Collier, B. R. Lucas, R. Cairns, R. Standen, and the Manchester 

 Museum. Practically all the known species and varieties of this interesting genus 

 were exhibited, but in the discussion which followed there was a general opinion 

 that too many species had been made out of what may be merely local forms of the 

 .same thing.
