MELVILL AND STANDEN: SHELLS FROM LIFU. 07 
of the last, are few ribbed, and transversely crossed twice or 
thrice with strong projecting corded ribs, the last whorl is many 
ridged and many corded. Mouth oblong, with a very strong 
prominent tooth in the outer lip, which is, besides, 4-denticulate, 
the columellar margin being also 4-denticulate. Canal rather 
short. 
We have much pleasure in associating the name of Mrs. 
Emma Hadfield with this attractive little shell.

This very interesting little shell we place provisionally 
under Glyphostoma, from which assemblage it differs in the 
simple outer lip and more uniform shape. ‘The inner or 
columellar margin of the lip possesses seven or eight close and 
minute plice, there is also one minute process at the parietal 
sinus. It is of a graceful attenuate form, six-whorled, or 
perhaps seven, but the apex is broken off in the only specimen 
we have. The pure whiteness of the shell is relieved by a row 
of brown spots between the ribs just above the sutures and in 
the middle of the last whorl. The specific name is from the 
Greek OéeoxeXos ‘wonderful,’ in allusion to the strange configura- 
tion of the species. 
M. (Cythara) cithara Gould.—A few pretty specimens. 
M. (Cythara) inepta Smith.—One fine specimen. Hitherto
