preceding joints armed on their inner edges with plumose setae, the merus liaving, 

 in addition, ordinary setae, the carpus armed with a few simple setae, the propo- 

 dus similarly armed to the carpus. Second thoracic legs relatively shorter than 

 in the type species, with the merus slightly longer than the carpus, propodus very 

 small, nail distinct and longer than the propodus; latter armed with about five 

 plumose setae at its tip in addition to a few simple setae, not nearly so densely 

 armed as in the type species; remaining joints feebly armed with simple setae 

 only. Endopods of the remaining thoracic limbs missing in the type specimens. 

 Exopods of the thoracic limbs well developed, those of the first and second limbs 

 longer than the endopods, outer distal corner of the basal Joint slightly acuminate, 

 flagelliform part of ten joints. Pleopods of the female as usual for the genus, 

 those of the male well developed, natatory, inner brauch of the first pair a short 

 rounded lobe armed at the tip with three setae and with three setae near its base, 

 lateral lobe rather narrow with two setae at its tip; second, third, and fifth pleo- 

 pods of the male consisting of two equal multiarticulate branches, the inner brauch 

 with the usual lateral lobe; fourth pair of pleopods of exactly the same structure 

 as the others but with the outer brauch terminating in a very long strong seta, 

 quite simple and longer than the whole pleopod itself. Telson as long as the 

 last Segment of the pleon, lateral margins straight, whole telson gradually narrowing 

 to its apex, latter broadly rounded, entire, armed with three (? sometimes four) 

 pairs of equal spines, which are about one-fifth of the length of the telson, and 

 are adorned on each side with a closely set row of minute spinules or setae; 

 median setae absent; lateral margins armed with about thirteen short spines 

 occupying the distal two-thirds of the margin. Inner uropods about one and a 

 quarter times as long as the telson, ciliate all round, with a Single spine at the 

 inner posterior corner of the otocyst. Outer uropods about one and a third times 

 as long as the inner and broader than the latter. Length, 10 mm." (Holt u. Tattersall,

„Form robust, compact sublinear in shape. Carapace not much wider than 

 pleon, emarginate posteriorly, evenly rounded in front, cervical sulcus well marked. 

 Pleon with the first segment longer than next four, which are sub-equal in length, 

 last segment about twice as long as the preceding. Ocular lamina slightly cleft 

 in the middle dorsal line, composed of two sub-rectangular contiguous plates, rather 

 large, minutely hispid all over; teeth about twelve in number, confined to the
