South African Crustacea. 253 



The fifth pair have the fourth joint rectangular like that of the 

 preceding pair, but narrower, and followed by a much narrower fifth 

 joint of equal length ; the sixth joint is shorter, and perhaps carries a 

 minute nail. In all three specimens the seventh joint appears to have 

 no representative in the fourth and fifth peraeopods other than a 

 microscopic nail. To the smalluess of the nail in the second and. 

 third pairs reference is made in the specific name. This will be still 

 more applicable to the case of the fourth and fifth pairs if appearances 

 can be trusted ; nor is it likely that all three otherwise well-preserved 

 specimens would have suffered precisely the same injuries. 



The characters of the large first and small second pleopods of the 

 male are sufficiently shown by the figures.

 of genus and species see Marine Investigations in South Africa, no. II,

An ovigerous female specimen, 17 mm. broad and slightly over 16 mm. 

 long, was obtained by Dr. Gilchrist at the locality " Cape Point 

 N. 81 E., 32 miles; depth 460 fathoms." A rather smaller specimen 

 was devoid of its pleou.

The leading character for the distinction of this genus from 

 its neighbours is, as Borradaile expresses it, the " front deeply 

 cleft into two prominent rounded lobes." To this may be added 

 the very small pleopods on the sixth pleou segment of the female, 

 and the sternal grooves of that sex ending together. Some 

 of the characters based on the typical species, E. frontalis, 

 Henderson, such as " legs not knobbed or ridged," and " the 

 length exceeding the breadth " of the carapace, would exclude 

 the species now to be described.
