EXPLANATION 



OF THE 



mjk^^i^ 



PLATE I 



Figiufi 1. BuLiMUs cincliis, Nobis. 



Habitat, Calcutta. 



Remarks. — In the event of this shell not having been previously described, 1 

 propose the above name for it, from the AVhite Band with which the body whorl 

 is girt. For the possession of this rare Bnlimus I am indebted to Burn W. 

 Bndd.M.D. of this City. 



Figure 2, 3. Turbo Rotelliformis, Nobis. 



Habitat, South Seas. 



Remar.'cs. — This shell was brought into Boston during the last year, and ap- 

 pears to be nndescribed; on the upper surface it has every appearance of a 

 large Rotella, but underneath the large and deep Umbilicus shows that it does 

 not belong to that Genus. Should it prove to be new, a description of it will 

 appear in the Annals of the Lyceum of Natural History of this City.
