198 AMERICAN JOURNAL 



Shell shortly ovate, rather solid, narrowly umbilicate, trans- 

 versely marked with fine crowded strife ; whorls 4 J, planely 

 convex, generally marginated at the sutures ; aperture oval, 

 edentate, slightly oblique; columella slightly nodosely callous 

 on upper part. Light horn color, or chestnut horn color, or 

 chestnut, obscurely finely striped longitudinally. 



Yar. Yery rarely encircled by three interrupted chestnut- 

 brown bands. 



Observations. — The above has been referred to decussatula, 

 Pfr., by Mr. Cuming, which inhabits, as reported, the Solomon 

 Islands, but, as we are inclined to believe, the Samoan. Our 

 species is thicker, rather more stout, whorls are not rounded, 

 and the aperture differs from decussatula.

 lida, dextrorsa, parum glabra ; anfr. 5, plano-convexis, sutura 

 bene impressa, interdum marginata ; labro anguste, £Bqualiter 

 et subrotunde incrassato, dextro recto, superne subangulato.

 dextral, somewhat glabrous ; whorls 5, planely convex, suture 

 well impressed and sometimes marginated ; aperture ovate, 

 vertical, dentate, rounded at base ; lip narrowly, evenly, and

 lineata, Less., as well as elongata, nob., to which refer for my 

 remarks.
