Sir. T. D. A. Cockerell read a paper on the geographical distribution 

 of Slugs. The author divided the known Slugs into six families: — 

 Succineida, Vaginulida, Arionidce, Limacida, Testacellidce, and Selenitida,

 to a subfamily of Succineida, and the generic nomenclature of the whole 

 group was revised, two new genera and one new subgenus being named. 

 The Philomycida were made a subfamily of the Arionida. The distri-

 Madagascar, was indicated.
