THE MOLLUSCA—HEDLEY. 411 
I cannot, from published data, separate the later described Z. 
solida, Sowb., and H. inflewa, Pease. Granted this synonomy, 
the species extends to Fiji, Paumotus, and Hawaii. 
EULIMA DECIPIENS, sp. nov. 
(Fig. 4). 
Shell small, straight, rather broad, translucent, 
glossy. Colour porcelainous white. Apex mucro- 
nate. Whorls eleven, scarcely rounded, sculpture 
none. Suture scarcely perceptible; what first 
appears to be the suture, proves with further 
magnification to be the internal septa seen 
through the shell substance. Aperture pyriform, 
oblique, with a callous arched columella. Length 
5, breadth 14 mm. 
One living specimen from the lagoon. 
This species somewhat resembles Z. piriformis, 
Brugnone, than which it is rather narrower. 
STYLIFER VARICIFERUS, Sp. Nov. 
(Fig. 5). 
Shell ovate conical, thin, translucent and shining. Apex broken 
but apparently acicular. Remaining whorls nine, of which the 
latter are markedly tumid and narrow, giving the shell a squeezed 
or telescoped aspect. The upper whorls are smooth and polished, 
the lower gradually. acquire an oblique, longitudinal sculpture 
which becomes coarser as the shell proceeds and finally on the
