Mr. A. Adams obtained two similar species from Japan ; and 

 as the shells do not rank satisfactorily under any established 

 group, he proposes the above genus for their reception. M.Crosse 

 suggests that Columbella dormitor, Sby., may be congeneric. 



Mangelia variegata. 



M. testa valde attenuata, tenui, parva, pallida carnea, rufo-fusco 

 normaliter bizonata, interdum unizonata, seu zonis interruptis; 

 Venice nucleoso conspicuo, anfr. uno et dimidio, apice mamillato ; 

 anfr. norm, vi., subrotundatis, suturis valde impressis ; costis 

 radiantibus ix., angustis ; costulis spiralibus crebris, validieribus, 

 in spira circ. x., cestas superantibus ; apertura valde elongata; 

 canali brevi, aperto ; labre tenui, juxta suturam conspicue arcuato; 

 labio tenui. Long. -31, long. spir. -17, lat. •! pell., div. 22°. 



Variat costis crebrioribus, sculptura minus expressa. 



Hab. Sta. Barbara [Jewett). 



Mangelia (? variegata, var.) nitens. 



M. testa M. variegata simili, sed uitentiore, fascia alba et altera
