The original description was based on male specimens, but 

 Stebbing (I.e. p. 66) mentions a smaller specimen which " differed 

 from the largest and from the one figured by having the telsonic 

 apex simple, not trilobed, and by having much-reduced lobes on the 

 basal part of the telson." 



Two large females agree with this description. Moreover the 

 uropods are shorter and do not reach the telsonic apex. The only 

 setae present on the pleon and uropods are : a row along the basal 

 margin of 6th segment in advance of the insertion of the uropods ; 

 a tuft on the outer margin of peduncle of uropod ; a tuft on inner 

 apical angle of inner ramus ; and a tuft on the underside of telson on 

 either side of the terminal notch. 



The hind margins of the peraeon segments are not cut into blunt 

 denticles as in $ , but segments 1-5 are ornamented each with a 

 transverse row of 7 tubercles (1 median, 1 medio-lateral and 2 

 lateral), and segments 6 and 7 with a row of 6 tubercles (the median 

 one being absent). The medio-lateral tubercles gradually converge 

 posteriorly. On segments 6 and 7 there is a small inconspicuous 

 tubercle between the medio-lateral and lateral tubercles. 



The peculiar pittings on the integument of $ are inconspicuous 

 in $ . 



Though apparently nearly full grown, these specimens are not 

 ovigerous, and the mouth parts are not modified.
