38. Of thefmallTrochus, or ftriated papillaceous top-fhell, with 

 five Volute (u), I have gathered a quart or two at a time, with 

 the fimes in them, at ebb-tides among the fea-rocks, near Emble- 

 ton. The inveftient Cuticula of the fhell is brown, and very 

 rough. When polifhed by the collifion of the fands and tides j 

 it is of a beautiful pearl-colour, with brown ftriGe, tranfverfe, 

 and wavy. 



39, 40, 41. The Trochus with fix Volute, and an acuminated apex 

 (vj ; the fmall ftriated Nun or Venus-Shell (w) ; and the very fmall 

 deprejjed orbicular Cochlea, are frequently brought on ftiore empty ; 

 the firft moft rare and moft beautiful, with red fpots on a pearl- 

 coloured ground ; the fecond often gathered on the fhores near 

 Embleton, and at Holy- I/land ; the laft, with only one wreath, is 

 found in great numbers on the foliage of fubmarine plants. 



The frem-water fliell-fifhes, the Mytul'i jluviatiles, or River- 

 Mufcles, are plentiful in moft of our rivers.
