A very distinct large smooth-whorled snail, not easily to 

 te compared with any other Cape species. We have great 

 pleasure in uniting with this the name of its discoverer, J. 

 Crawford, Esq., to whose indefatigable researches we are 

 indebted for the whole of the material in this paper.

 and consequently demanding a rejoinder on my part.
