Habitat. — In sandy bays plentifully, from half-tide 

 to low-water, and sparingly to a few fathoms 

 beyond low-water. When put into a vessel with 

 water, they dart through it with great rapidity; but 

 they soon settle down with their tail under their 

 body, forming an oval like a small barley-corn, by 

 which they can be readily distinguished. When a 

 little sand is introduced, they burrow quickly into it. 

 When in life, their eyes are a bright red covered 

 by a white areola ; and these organs may almost 

 be said to be confluent, so closely do they come 

 together on the front of the head, although in 

 many cases a thin ridge may be seen between 

 them.
