by filtli, and acquires a reddish colour. It is sought 

 for during the night by the Urtica : the Cancillus 

 sometimes grows in it. By cooking it becomes 

 digestible, and is very agreeable when stewed with 

 ciiMiamon and pepper. According to Athenasus, the 

 white pecten is the best, and the largest of the red 

 and dark coloured best in spring, whilst, according

 fection near Mytilene. Pliny, Clemens Alex- 

 andrinus, and Methymneus speak of their medicinal 

 virtues." It will be noticed that in this description 

 it is said that this shell-fish springs about. Volitat. 

 This statement is given on the testimony of Aristotle, 

 Pliny, and Massaria, and in their works is more largely

 abundantly confirmed. If a basket of the common 

 pecten be placed near the water-edge it will be seen 

 that it is speedily emptied, by its inmates springing

 This is effected by the sudden opening and shutting 

 of their valves, the lower striking against the sand 

 and acting as a spring*.

 he really is, and when and where he was seen. 

 The description of the sea-horse is given by Isidore
