Shell, seen from the side, siliquose, greatly curved, greatest height equal to 

 two-fifths of the length, behind the middle ; anterior half of much less height 

 tlian the posterior, and bending downwards; anterior extremity narrow, but well 

 and evenly rounded; dorsal margin strongly arched throughout, without any

 ventral margin deeply concave in front of the middle, behind the middle gently

There are only two Ostracoda which this very small species can be said to
