Dorsal carina from peraeon segment 5 to pleon segment 4, the denti- 

 form projection encreasing in skength on successive Segments, subdorsal 

 carinae ending in a small tooth on each side of the Segments. Head, rostrura 

 reaching slightly beyond 1^* Joint of antenna 1, post-antennal corners 

 subacute. Pleon segments 1 and 2, postero-lateral corners with 2 projectiug 

 angular points, segment 3, postero-lateral corners acute, strongly produced, 

 without Upper projecting point. Eyes rather large, piriform, brilliant carmine. 

 Antenna 1 not very long, P* Joint longer than 2^ and 3"^ corabined, flagellum 

 about twice as long as peduncle, 20-jointed. Antenna 2 not much louger, 

 ultimate and penultiniate joints of peduncle subequal, flagellum twice as 

 long as peduncle. Gnathopods 1 and 2, 5*^ Joint as long as 6*^ 6*^ slightly 

 widening to not very oblique palm. Peraeopod 5, 2^ Joint as long as 3*^ — 6*^ 

 combined, widened except at distal end, which is produced to small acute 

 lobe. Uropod 3, rami long, not very broad, spinules few. Telson oblong 

 oval, apical margin insinuate, not deeply. Colour dark red, especially at 

 bind margin of segments. L. Q about 9 mm. 



North-Atlantic, North-Sea and Skagerrak (South- and West-Norway). Semi- 

 parasitic on Holothuria tremula Gönn.

Much indurated, carinate from peraeon segment 1 to pleon segment 4, 

 laminar, obtuse, backward produced processes, encreasing in size successively 

 to pleon segment 1, on 2^ — 4*^^ more acute, on 4**1 diminished in size; 

 peraeon segments 1—7 with subdorsal lateral tubercle, pleon segments 1 — 3 

 with 4 lateral tubercles, 4*^ with one and a ridge, 5*^ and 6*^ centrally faintly 

 carinate. Head not carinate, rostrum very long, acute, reaching end of 

 peduncle of antenna 1. Pleon segments 1 — 3, postero-lateral angles acute, 

 with another tooth above the produced point, pleon segment 2 with tooth 

 at antero-lateral corner. Eyes very prominent, rounded or oval, rieh 

 vermilion. Antenna 1, 1^* Joint longer than 2^ and 3*^ combined, flagellum 

 nearly thrice as long as peduncle, with about 30 joints, 1^* longest, accessoiy 

 flagellum 1-jointed, ahnost rudimentary. Antenna 2 not much longer, ulti- 

 mate Joint of peduncle shorter than penultimate, flagellum with 50 joints 

 or more, 1^* longest. Upper lip faintly insinuate at naiTOwed apex. Maxiila 1, 

 inner plate with 9 setae, outer with 11 spines. Gnathopods 1 and 2 stronger 

 than in other species of the genus. Gnathopod 1, h^^ Joint nearly as long 

 as 6*^, twice as long as broad, 6*^ oblong, a little widened at the short, 

 serrate, almost transverse palm, finger armed on inner margin with 12 spines. 

 Gnathopod 2 like gnathopod 1, but 6*^ Joint longer. Peraeopods 3 and 4, 

 2^ Joint deeply grooved behind; peraeopod 5, 2^ Joint not equal in length to 

 3d — ßth combined, expanded above, produced into a naiTow lobe below. Uropod 3, 

 rami long, broad, ending very acutely. Telson little longer than broad,.
