«I never remember having seen this shell with any shells or peb- 
bles attached to it, but the first two or three whorls sufficiently indi- 
cate that some have been agglutinated to it at one time or another 
by the numerous indentations which they exhibit. The under sur- 
face of the shell is generally marked with a circular brown band, the 
centre being widely umbilicated.”

“This shell exhibits very slight evidence of ever having had any 
matter agglutinated to it. It somewhat resembles the preceding 
species, but may be readily distinguished by the elaborate manner in 
which the whorls are diagonally carved with grooves and striz. ‘The 
periphery of each whorl is most unusually dilated beyond their 
laminal bases; it is exceedingly thin and fragile, and very unevenly 
undulated.”

“«T have seen several specimens of this very pretty species; the 
shell is of a bright subrosaceous fawn-colour, and entirely covered 
with fine diagonal striz and cross grains. The agglutinating property 
_ seems confined to the upper portion of the whorls, so that there is 
always a band of fine pebbles or shells around the sutures, and they 
exhibit a regular increase in their selection as the agglutinating 
surface increases with the growth of the shell.”
