The fact tliat both the forms referred to this ^cnus were 

 found in wells suggests that they belong to the subterranean 

 fauna. Tiie eyes, however, although small, are well-pig- 

 mented and facetted. Certain blind forms referred to the 

 genus Palcemonctes have been described from subterranean 

 habitats in Texas and in Cuba. They are still imperfectly 

 known and it does not soem certain that they are correctly 

 assigned to that genus. They are certainly si)ecifically, and 

 probably generically, distinct fioui the forms here dealt 

 with.
