Sniitli sugg'ost('(l lliiit rrinij(( Gray might bp sviioiiymoiis with tliis 
species, writing: It seems to me jiroljable that tlie //. tor::'Hs yer., is identical 
with this si)ecies {rcliu/a). It was collpct(‘d by I’eron (hiring one of the early 
Frimch voyages, but the exact |tart of Australia, wliere lie obtained it is not 
stated. Accepting this suggestion Hedh'v used toridnx, and I utilised it in 
the Ba.sie List, but in the moi’e detailt'd examination necessary for this 
account 1 found too many diserepaucu's, and now record ioruJns as available 
for a Shark Ray shell, whicli is not at present in our collection. 
Deshayes’ descrijition agrees vvilh the ligure which sliows a subglobose, 
subpei’torate shell, smooth, whit(' with one anl(‘-|)eri])heral brown band : the 
sutures deep, the whorls convex. The illustration is of a shell of the Shark 
Bay form, being more eonv(>.\ than the more northern rehiga series.

I his spcu'ie.s was described as “depressedly globose, oblicpiely striate, 
whitish, with one chestnut band and man.v orange lint's; spire little elevated, 
whorls convex; aperture obliipu' narroiv; with a hidden perforation and an 
obtuse tooth on the base of the mouth, breadth 15, hei,ght 10 mim. New 
Zealand.” 
I he slu'll had not conu' from New Zealand, apparently Pfeiffer being 
misled by inspt'ction of a plate of New Zealand shells which Gray had had 
prepared. This plate was never issued. A s]iecimen fi'om Broome is here 
figured as it agret's with the tigure and description, and the original s|)eeimen 
may have been collected at CygiU't Bay along with ieptogramma described 
about the same time.
