This is a very small species presenting all the characters 

 of a typical Cypridopsis — somewhat like 0. newtoni in

Shell seen laterally renifonn, highest in the middle, height 

 equal to more than half the length (fig. 1), anterior margin 

 broadly rounded, and produced at the ventral angle so as to

 of the terminal claws (fig. 3) ; mandibular palp rather short 

 and stout (fig. 4) ; apices of posterior feet simply setiferous, 

 not forcipate ; caudal rami (fig. 7) simple, setiform. Ejacu-
