Body rather stouter than in P. sophia; head with lateral lobes 

 more acutely produced with less convex lower margin. Side-plate 1 not 

 very small, 2*^ in ö broader than deep, 5*^ fully as deep as 4*^. Pleon 

 Segment 3, postero-lateral coruers with obtuse point scarcely produced. Eyes 

 of moderate size, rounded oval, dark. Antennae 1 and 2 equal, more than 

 V2 as long as body; peduncles as in P. sophia; flagellum of antenna 1 

 12 — 16-jointed, of antenna 2 13-jointed. Upper lip feebly emarginate, 

 produced in front to a sharp point. Mandibular palp not very slender. 

 Gnathopod 1 very slender, 6*^^ Joint scarcely as long as 5*^, subfusiform, 

 finger very long. Gnathopod 2 in (5, 5*^ Joint shoi-t, cup-shaped, 6*^ very 

 large, oblong oval; palm minutely tuberculate, with a median sinus between 

 2 lobes, that near the finger -hinge truncate and a little emarginate, the 

 other dentiform not far from the defining angle, which is scarcely reached 

 by the broad curved finger. Gnathopod 2 in g as in c5", except that the 

 cavit}^ in the palm is wider, not bounded by a separate lobe near finger- 

 hinge, and the tooth on the other side is closer to the defining angle. Peraeo- 

 pods 1 — 2, 4*^ Joint not nearly as long as 5'^ and 6*^ combined. Peraeopod 3, 

 2*^ Joint nearly as broad as long. Peraeopods 4 and 5, 2*^ Joint oblong 

 oval, üropod 3, rami rather unequal, a little shorter than peduncle, the 

 Inner the larger, tipped with 2 setules. Telson as broad as long, with 3 

 slender spines on either side of apex. Colour, variegated with dark brown, 

 especially along the sides. L. 7 — 8 mm.

Body slender. Head, lateral lobes projecting. Side-plate 2 in d the 

 largest, 3*^ and 4.^^ successively smaller. Eyes well developed. Antennae 1 

 and 2 very slender. Antenna 1 the shorter, with veiy small accessoiy 

 flagellum. Mouth-parts as in Eurystheus (p. 610), except that 3^ Joint of 

 mandibular palp is relatively shorter. Gnathopods 1 and 2 with b^^ and 6*^ 

 joints elongate, strongly developed though weakly subchelate in c5, feebly 

 developed, almost simple, and subequal in 9 . In other respects scai-cely 

 differing from Eurystheus.
