Probably rather common in sand and mud on the Bay of Fundy coast, and perhaps less so on the Atlantic shores. May be very rare or quite wanting in the Gulf of St. Lawrence. Habits. This is a very striking sliell, and one easily distinguished from all others by its ten raised revolving ribs. The ground color isadul}, fulvous or yellowish-red, but the ribs are darker. Of these there can always be counted nine, generally ten and rarely more on the lower whorl, of which only two, rarely three, revolve on the upper whorls. The ribs being large and very solid, give the shell a handsome fluted appearance. The lower end tapers to a canal. It is about three inches in length, though frequently somewhat larger. It seems to prefer mud and sand bottoms in rather shal- low water on our coasts, rather than rocks in deep water as Gould suggests. In L'Etang Harbor it is often dredged with mud, but occurs in greatest per- fection and beaut}' in the clean sand and clear water about low- water mark, at Hospital or Little Hardwood Island in Passama- quoddy Bay. There it lives half- burrowing in the sand,with only its spire projecting at times, and Fig. 3 -F«ms decemcomtm. leaving deep furrows behind as si7e. it works its way along. Specimens from this locality are very clean and bright and show no trace of the parasitic growths w^hich Natural
