Mostly inhabi- tants of north- ern and Antarc- tic Seas they range from the Fig. 48 Egg case of Buccinum undatum shore to a depth of 100 fathoms. BDCCINUM UNDATUM Linne. Waved Whelk. An opaque, almost lustreless shell, sculptured with many fine thread-like spiral ridges arranged in groups; whorls seven to eight; shell wall glazed near inner lip; opercu- lum pale yellow with layers of growth re- sembling the epidermis of shell. Length inches. There are many extraordinary varie- tal manifestations of this species, dwarfs, keeled, elongated, thin, reversed, two to three operculated shells. Some of the most remarkable have been taken off the English coasts. It lives from tide mark to consid- erable depths. In America the specimens are slightly smaller than the European ones. Tons of these whelks are carried to the British fish markets. In the year 1504, when Warham was enthroned Archbishop of Canterbury, there were provided for a feast '8,000 whelks at 5 shillings per 1,000.' The curious spawn cells are called 'Sea Wash Balls' on account of their being used by sailors to wash their hands.
