290 MELVILL AND STANDEN : SHELLS FROM LIFU. 



Very small, and with some slight resemblance to M. thepa- 

 lea. The nodulous papillre are, however, much larger in pro- 

 portion to the size of the shell, and, in consequence, fewer. 

 The upper whorls are closely tubercled, shining white. The 

 four rows — two on the penultimate, two on the last whorl 

 — are approximate, and the space contained by them is banded 

 with ochre, the white shining nodules standing out more promi- 

 nently. The mouth is narrow, oblong, sinus deep, outer lip 

 much thickened, four toothed within as is the columellar 

 margin. Rare; we have seen very few examples. (6>eoTeA?ys

A very delicate, beautiful little shell. It is pyramidally 

 spindle-shaped, white, with seven whorls, two being glassy and 

 apical, the rest ventricose, impressed at the sutures, the longi- 

 tudinal ribs are nodulous, shining, and very regular, one spiral 

 sulcation crosses each rib in the middle, the interstices between 

 are beautifully longitudinally striolate. At the sutures, and in 

 the middle of the last whorl (in some specimens also on the 

 upper whorls), there is a very pale ochraceous banding, the 

 nodules of the ribs still retaining their white lustre. In other 

 specimens the first three or four whorls remain quite colourless. 

 The mouth is oblong, sinus sutural, obliquely extending over the
