1 8 Melvill, Molluscan Fauna of the Arabian Sea, etc. 



A thin, waxy little Bullia, with a superficial resem- 

 blance to certain Nassae, e.g., N. teretiuscula Ad., and 

 pulchella Ad. Very smooth, slightly shining, cinereous 

 drab in colour, seven whorled, two being apical, swollen, 

 vitreous, the rest all longitudinally ribbed, the ribs very 

 smooth, as are the interstices, the last whorl about equals 

 the remainder put together, here the ribs disappear below 

 the middle of the whorl, and in their place are several 

 spiral deeply sulcate lines around the base of the shell. 

 The aperture is oval, outer lip a little effuse. 



Ten or twelve specimens.

This cannot be confounded with B. lineolaia ( = Belan- 

 geri Kien), there being no trace of fulvous marking, nor 

 is the shell of the same consistency, being far more delicate. 

 The transverse sulculi, too, in B. lineolata, are only partial 

 over the whorls, leaving a considerable space below the 

 sutures smooth, with the exception of a once folded 

 sutural plait. The species before us is ovately fusiform
