 N. siituralis var. = recurva (Sowb.). 



C. spiralis and D. spiratns are very common, the former 

 on rocks, the latter in sand. Cfuscata may frequently be 

 found at very low tides from its habit of exposing itself 

 when left stranded. It apparently burrows in sand. In its 

 normal form it appears to be a somewhat smooth-backed 

 shell with marbled markings and white transverse lines 

 filetted with brown. Some specimens, however, are longi- 

 tudinally corrugate, and they do not appear to have the 

 beautiful coloration just mentioned.
