 twice as long as broad, and tapering behind to pointed extremity. 

 Abdomen length one-half entire body length. Head about twice 

 as broad as long, front not emarginated between anterior lateral 

 lobes but expanded be}ond them. Lateral edges of head cleft, 

 front lobe smaller than hind lobe, and latter projecting at sides 

 beyond anterior one. Front with decided median excavation 

 with median point in its center. Eyes compound, small, rounded, 

 situated dorsally at base of post-lateral lobe. First antennce with 

 basal segment very short and not expanded, second segment little 

 longer than first, and third and fourth equal segments about 

 twice length of first. First antenuc-e reach little beyond end of 

 peduncle of second antenna. Second antennae with basal seg- 

 ment not very evident in dorsal view, second, third and fourth 

 segments subequal, and fifth segment little longer than fourth. 

 Flagellum formed of five articles. Retracted second antennae 

 reach front edge of first thoracic segment. Maxillipeds with 

 palp of three segments. Thoracic segments of equal length. 

 Epimera separated dorsally from first three segments, not acutely 

 produced behind. Epimera of last four segments also distinct, 

 produced into acutely pointed processes. Abdomen formed of 

 four segments, as three short ones followed by long-pointed 

 terminal one, with lateral sutures of another partly coalesced 

 segment. Apex of terminal segment acute, its lateral edges 

 near end denticulated. Abdominal sides taper gradually to about

 on either side half way from base to apex. First three pairs
