The iiext paper was also communicated by Mr. Loveli Reeve, and 

 contained " Descriptions of fifty-four new species of Mangelia, from 

 the coUection of H. Cuming, Esq.": — 



, The Mangelioe are nearest allied to those aberrant species of Pleu- 

 rotoma in -vvhich the predominant character of that genus, the fissure 

 in the upper extremity of the lip, becomes modified into a somewhat 

 obscure sinus. Their general aspect is that of a more or less fusiform 

 Marginella, without plaits or polished exterior; distinguished, on 

 the other hand, by a iow of faint wriakle-like denticulations on the 

 inner surface of the lip and columella, and a gutter-like sinus in the 

 lip at its junction with the body-whorl.
