3. THE PECTENS (No. 1) 



A globe trotting collector would be able to gather about two hundred and fifty 

 species of pectens if he were equipped to search in deep water as well as shallow. 

 He would spot a colorful scallop peering at him with its row of luminous little eyes 

 fringing the edge of its mantel, each equipped with cornea, lens and optic nerve. As 

 he stertched forth his hand to grasp this treasure he would probably be disconcerted 

 at the hasty flight of the pecten darting out of reach by rapidly opening and 

 closing its pretty valves. 



The adult is usually free swimming, but when a juvenile it spun a byssus through 

 a notch in the shell and attached itself to some stationary object. 



The pecten with its radially ribbed surface, scalloped margins, diversity of color 

 and pattern has inspired the artist through the ages. Pilgrims to the Holy Land 

 wore a Mediterranean species as a badge of honor. Today the scallop is the 

 handsome trade mark of an international oil company.
