I am indebted for the specimens which form the subject of the 

 following notes to my friend the Rev. Canon JsForman, F.R.S., 

 by whom they were collected in the spring of the year 1897. 

 The mountings submitted to me consisted altogether of dried 

 shells, and in no case was the contained animal preserved, 

 excepting in a few of those collected between tide-marks, 

 and only in some of these littoral forms was the original colouring 

 discernible. Apart from such as appear to be new to science, 

 the collection is interesting as extending the known range of 

 several species from the European and IsTorth Atlantic areas much 

 further southward, though not quite into the tropical zone. All 

 the species belong, so far as can be ascertained from the shell- 

 characters, to well-known genera. The foilowmg lists show 

 separately the species found in the littoral zone and in deep 

 water.
