us, but as it is said to belong to Section Simpulum, whereas our 

 species belongs to Gutturnium, the two must be regarded as 

 distinct. 



Cantharus kingieola, spec. nov. 



Shell fusiformly oval, somewhat solid ; colour opaque-white, 

 except the summit, which is pale-orange. 



Nucleus small, of two and a-half smooth, convex turns. 

 Spire-whorls five, slopingly convex, subangulated towards the 

 anterior by reason of the greater volume of the axial costae. The 

 axial ornamentation consists of close, elevated, rounded, straight 

 costae (twelve on the penultimate whorl), which thicken very 

 rapidly as they approach the front suture (there they are about 

 twice as wide as the interspaces). The spiral ornament consists 

 of roundly compressed valid lirse (seven on the penultimate 

 whorl) which cross the costae, and of a sutural adpressed band. 



Body whorl convex, contracted anteriorly ; there are twelve 

 axial costse, which are most developed at the rounded periphery, 

 and become evanescent in front of it; there are about 15 spiral 

 lirae, fairly regular, with occasional interstitial threadlets, and 

 there is a sutural band. 



Aperture elongately oval, half as long as the shell. Outer lip 

 uniformly convex, varicosely dilated ; acute, prominent lines 

 within. Columella concavely arcuate, not plaited at the base. 

 Beak short, rather wide, slightly upturned. 



Length, 18; width, 9 mm. 



King Island ; two specimens. 



Marginella cratericula, spec. nov. 



Roundly obconic, somewhat bullaeform, having the general 

 features, as regards shape of a Bullinella, translucent, shining, 

 bluntly rounded posteriorly (where the shell is widest), rapidly 

 attenuating to the subacute front. Spire concealed and sunken 

 to form a shallow crateriform depression. 



Outer lip slightly thickened, smooth on the inner margin. 

 Columella with two closely approximate large plaits ; the anterior 

 one the larger, terminating in a slight anterior emargination. 



Length, 2-3 ; width, 1*5 mm. 



D'Entrecasteaux Channel, Tasmania ; 10 fathoms ( W. L. May), 

 two examples. 



This species is conspicuous by its impressed spire, which 

 separates it from all other Marginellidae. 



Marginella multiplicata, spec. nov. 



Shell minute, rather solid, shining white, having much the 

 shape of M. Isseli. Spire concealed. Aperture equalling the 

 total length of the shell, but not extending much beyond the
