" This species is abundant all along our sandy 

 shores, near high-water, under decomposing sea- 

 weed ; and higher, above the ordinary tide-mark, 

 where they burrow to the depth of three to four 

 inches, ' till they find sufficient moisture for their 

 wants and comfort.' Their burrows are small, round, 

 perpendicular holes, about the size of a goose-quilL 

 In some places the sand is so much riddled that the 

 holes are very conspicuous. If rudely disturbed, the 

 occupants are seen leaping about in all directions, 

 and it takes nimble fingers to get hold of one of 

 them. When the sand is gently rubbed off, layer 

 by layer, with the edge of the hand, till the animals 

 are partially exposed, they lie motionless, seemingly 

 feigning death ; but if tossed out, as already stated, 

 they at once bound olf, endeavouring to escape, 

 which most of them generally succeed in doing.
