 kind of sea-urchin ; whilst his " little sort, with 

 very long and hard spines, and living in places 

 where the sea is many fathoms deep," and of

 spines would attract attention at all times from 

 the fisherman, among whose lines they would get 

 entangled, when set in water of a depth of 

 from forty fathoms downwards. It is abundant 

 in places on the Lycian coast. 



Besides those enumerated there is the little 

 Echinus monilis, better known as a fossil than as

 tribe, one of which, the Amphidetus mediterraneus,
