EUDORA. 151 



Devonshire (Montagu) ; Firth of Forth (Goodsir) ; Moray 

 Firth (Rev. G. Gordon). 



Cuma Edwardsii, Kroyer; Spence Bate. — Less com- 

 pressed than the last, more pointed in front, and five seg- 

 ments behind the carapace. 



Weymouth (Professor Williamson). 



Gen. 53. EUDORA, Spence Bate* 

 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. 



Plymouth Sound, within the Breakwater ; sent to Mr. 

 Bate by W. Webster, Esq. Some of the specimens had 

 eggs in the incubatory pouch.
