The specific limits within this genus are at present imperfectly drawn,

 difficult to decide just what species really are valid. Fortunately the color of 

 the type-species, bicolor, appears to be both constant and distinctive, and as it 

 is particularly mentioned by Agassiz, it makes his diagnosis of both species and
