half its size, has decided me, in the absence of other information to 

 regard it as distinct. A shell from Port Moresby closely resembles 

 the Ellioe one, differing by larger size and more swollen contour.

The inadequate description and poor figure quoted, suggest, but 

 fail to demonstrate, that a shell figured herewith should be so 

 named. The species is represented by a single, perforated and 

 decollated example from the Funafuti lagoon. It is 5^ mm. in 

 length, has thirteen whorls remaining, and in colour is ochraceous 

 splashed with white. The last whorl has six spiral ridges, two of 

 which are basal ; the three preceding whorls have each three, and 

 those above each two such ridges. The ridges are smooth, elevate 

 and keeled, the anterior of each series the larger ; on the upper

whorls the posterior ridge tends to divide into beads. The inter- 

 stices are broad, deep and finely spirally grooved. The spur of 

 the outer lip crosses the pillar. Anal notch deep and cordate. 

 Canal short and perpendicular. 



Pease described T. incisus from Hawaii.* I have collected at 

 Port Moresby, British New Guinea, what seems a form of that 

 described above. It differs in colour being variegated with black, 

 chocolate and white. The upperm9st ridge has not the same 

 disposition to become beaded but longitudinal plications are 

 developed in the interstices. The protoconch in these Papuan 

 shells is six whorled, bicarinate and crossed by coarse bars, like 

 the apex I figure for T. obesula.
