Mr. E. A. Smith (Jour. Linn. Soc., xii, 538), considers this a 
synonym of MW. 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 IW. citharella, having 
a plain lip, is a typical Mangilia.
