 ter nodoso-costata, costis rotundatis, remotis, vix obliquis, anfr. 

 ultimi inferne subevanidis, transversim confertim elevato-striata ;

Habitat. — Paumotus . 



Shell thick, oblong ovate, longitudinally nodosely ribbed, ribs 

 round, prominent, remote, somewhat oblique and curved, on the 

 spire and upper part of the last whorl swollen, becoming obsolete 

 on the lower part of the body whorl, transversely encircled with 

 close set elevated striae ; whorls rounded ; spire turrited ;

ReynarTcs. — The above species in shape and sculpture resem- 

 bles some varieties of M. ruhra^ Brod. 



The latter species, answering to the original description by 

 Broderip, occurs only at the Paumotus ; those of Reeve's de- 

 scription inhabit both the Hawaiian Islands and Paumotus. 

 There is still another distinct variety, lineated transversely, — a 

 perfect gem, when alive and in good condition.
