The chief peculiarity of the animal of Tapes (PulZastra, Sow.), as distin- 

 guished from the rest of the Conchacea, is the presence of a byssal groove 

 in the foot. The shell — and there are upwards of eighty species — is 

 characterized throughout by an oblorjg or obliquely oblong growth, densely 

 concentrically groove-striated, and of a uniform dull or rusty buff colour, 

 sometimes passing into pink, most frequently painted with sharply angled 

 hieroglyphic marks. 



Not more than about a tenth of the Tapes have been collected in the 

 Western Hemisphere. Throughout the Eastern Hemisphere they are 

 abundant, ranging from Australia to Northern Europe, four very charac- 

 teristic and good-sized species inhabiting Britain. Of these one, T. vir- 

 ginea, well illustrates the buff colour, passing into a delicate pink.
