GEOGRAPHICAL DISTRIBUTION. 



There is given here a list of the Stations and other places from which the Challenger 

 Expedition procured Scaphopods and Marine Gasteropods, so far, at least, as these have 

 been sent to me. The names of these molluscs from each locality have been added in 

 alphabetical order as simplest for reference, and all species first brought to light by the 

 Expedition are here reckoned as new.
