Although not very striking in appearance, this little shell 

 does not seem to suggest a close comparison with any hither- 

 to known species, but in external form it may be said to have, 

 on a very small scale, some resemblance to AI. patriarclialis 

 (Lamk.).

This pretty shell is unique as far as my knowledge goes. 

 Unfortunately I have no certain knowledge as to its habitat ; 

 but it was found in the collection of ]\r. Denans without label, 

 and most likely it was among the many fine shells collected 

 by that gentleman at Goree, West Africa.
