Remarks. — Three color phases of this species occur in New Jersey. 

 The most frequent is pale gray with darker mottling, giving a color 

 closely simulating sand; a second type is darker, the gray being 

 suffused with dusty-brown; the third type resembles the first, but 

 the body is much speckled with a pale green, giving the creatures a 

 striking resemblance to the crusts of reindeer-moss that are frequent 

 features of their habitat.
