For the sake of comparison the following description may first be 

 given. 



Male. Body strongly convex, nearly parallel-sided, minutely gran- 

 ular, setulose, more especially laterally. Head with the anterior margin 

 rounded and minutely denticulate, median process prominent, com- 

 pletely separating the 1st antennae and meeting the epistome, with a 

 small knob, sometimes bifid, on its upper surface. Head and 1st 

 peraeon segment without additional sculpturing. Segments 2-6 each 

 with 2 transverse rows of small tubercles ; segment 7 also with 2 rows, 

 but the rows not so distinctly separated from one another ; tubercles 

 larger on segments 6 and 7 than on the others. 



Pleou segment 4 with 2 widely separated, pointed processes, curving 

 slightly inwards and downwards and reaching to just beyond the middle 

 of telson, both inner and outer margins fringed with stiff setae ; lateral 

 portion of segment 4 also with a fringe of stiff setae on hind 

 margin. 



Telsou broader than long, surface covered with granules which are 

 rather larger than those on the rest of the body, in the middle 2 sub- 

 median white upstanding glabrous tubercles, somewhat chisel-shaped ; 

 apex deeply notched, the lateral lobes bifid and reaching a little beyond 

 the narrowly rounded, entire median lobe ; all the lobes with long setae, 

 distal margin with a small tooth just internal to the insertion of the 

 uropods. 



Antenna 1, 1st joint with 5 marginal teeth, increasing in size distally, 

 another rather larger tooth immediately ventral to the 1st tooth, 

 flagellum 6- jointed. 



Antenna 2, 4th and 5th joints with several long setae on outer 

 margin, flagellum ca. 10-joiuted. 



Epistome with the process obscurely bifid, or sometimes with indica- 

 tions of 4 teeth. 



Maxilliped as figured by Whitelegge. 



Male appendages on 7th peraeon segment close together, elongate, 

 slender, tapering to acute apices. 



Pleopod 2 as figured by Baker.
