The last cephalothoracic segment is expanded laterally, and 
bears upon each side a long seta. The fifth feet are attached to 
these expansions, are one-jointed, linear, and each bears at the 
tip a single seta. 
Females average a little more than \ mm. in length. The 
color in all the specimens I have seen has been purplish. My 
specimens agree very well with the descriptions of Sars and 
Schmeil, the only marked difference being in the length of the 
caudal setae. More complete descriptions of the European form 
may show other differences, but so far as the descriptions go f 
they apply very well to our form. 
G. bicolor occurs in stagnant pools, and is somewhat rare.
