This differs from Cuma in having the upper antenna ob- 
solete, lower antenna very short, consisting of a peduncle of 
three joints, and a filamentous terminal appendage. 
Eudora truncatula, Spence Bate. — The lateral angles 
of the carapace meet in front of the antennal segments, and 
are somewhat raised above them. The lower front edge is 
considerably produced, and gives a truncated character to 
the appearance of this species ; its margin is serrated.
