Mr. E. A. Smith (Jour. Linn. Soc., xii, 538), considers this a 

 synonym of M. citharella, Lam. This may indeed be the case, 

 but if so, we can retain but few of the numerous species of 

 Mangilia. It is narrower than that species, and the outer lip is 

 toothed, thus placing it in Cythara, whilst M. citharella, having 

 a plain lip, is a typical Mangilia.
