The absence of natatory set from the antenne prevents the mem- 
bers of this genus from swimming. They creep along the bottom and 
frequently burrow in the mud or sand.

Length 1.03 mm. Height 0.49 mm. Width 0.38 mm. 
The shell is more than twice as long as high and nearly three times. 
as long as wide. The shell being pellucid, the color of the enclosed 
body shines through the lorica and gives it a greenish yellow tint. 
Viewed from the side the shell of the female is sub-reniform; great- 
est height situated behind the middle; obtusely and evenly rounded 
in front, obliquely rounded behind. Ventral margin sinuated. 
Viewed from above the shell is compressed, tapering equally 
and suddenly to the two pointed extremities; sides almost parallel. 
Near each extremity a process from the left valve overlaps the right. 
The projection near the caudal extremity is much more pronounced 
than the other. 
The antenne are stout; the smooth terminal claws are slightly 
curved and are not quite as long as the combined lengths of the last 
three joints. Natatory sete are absent. For the arrangement of sete 
consult the figures. : 
The second foot is six-jointed. 
The abdominal rami are strong. In the female they are curved. 
The terminal claws are stout, curved and pectinate; the shorter claw 
is a little more than three-fourths as long as the other. The longer 
claw is about half as long as the entire ramus. Habitat: The 
only specimens yet found in America were found in a small 
spring-fed water tank on Clark University campus, Atlanta, Georgia, 
Aug. 30, 1894.
