Body robust, somewhat depressed, smooth. Peraeon Segments 1 and 2 

 Short; the rest longer, subequal. Head not strougly produced, obtusely conical. 

 Side-plates all very small, squamiform, subequal. Eyes very small, not 

 prominent, rounded oval, oblique, with a very light whitish yellow pigment. 

 Antenna 1 robust, as long as body, densely setose with long setae; S'^ Joint 

 of peduncle longer tban 2*^, or than the 4-jointed flagellum; accessory 

 flagellum very small, 3-jointed. Antenna 2 shorter and more slender, but 

 armed like the 1^*; ultimate and penultimate joints of peduncle subequal; 

 flagellum shorter than in antenna 1. Gnathopod 1 very setose; 6*** Joint 

 about as long as 5^^ narrowly oval. Gnathopod 2 in (5, 6*^ Joint very 

 setose, bind margin running out into a long palm-defining tooth, separated 

 by a deep and rather wide interval from the smaller tooth near hinge of the 

 strong, somewhat sinuous finger. Gnathopod 2 in 9 like gnathopod 1. 

 Peraeopods 1 and 2, 2*^ Joint somewhat dilated. Peraeopods 3 — 5 subequal, 

 robust, not very long, finger strong, falciform. Colour nearly translucent, 

 with faint yellowish pigmentation. L. Q 11 mm.

9 . Body rather slender, quite smooth. Peraeon segments successively 

 longer to the 4*''*. Head angularly produced in front. Side-plates all very 

 small, Eyes extremely minute, though well developed and with dark pigment. 

 Antenna 1 rather sti'ong, veiy long, densely fringed with long setae; 3"^ Joint 

 of peduncle much longer than 2*^, longer than the 5-jointed flagellum; 

 accessory flagellum minute, 3-jointed, Antenna 2 armed like antenna 1, 

 somewhat shorter; ultimate and penultimate joints of peduncle subequal. 

 Gnathopods 1 and 2 apparently as in D. porrecta (p. 712). Peraeopods 1 

 and 2, 2'^ Joint expanded, between oval and fusiform. Peraeopods 3 — 5 

 not very long nor very spinöse. Colonr in spirit simply greyish white. L. 5 mm.

Body extremely slender, long, smooth. Head-not very large, not much 

 produced. Side-plates all very small. Eyes without Visual Clements, represented 

 by patch of white pigment on each side. Antennae 1 and 2 extremely 

 slender and long, setose with short setae. Antenna 1 longer than the body; 

 flagellum in ö with 5 joints, in 9 with 4. Gnathopod 1, 4*^ Joint longer 

 than usual, 5*^ longer than the fusiform 6*^ Gnathopod 2 in d, 2*^ Joint 

 dilated only in distal half, 5*** Joint short, 6^^ with front margin veiy convex, 

 bind slightly concave, distally produced to a sharp tooth with smaller one 

 between it and hinge; the finger far overlapping both, with tubercle at its 

 base, its apex reaching the 5*^ Joint or nearly. Gnathopod 2 in 9 like 

 gnathopod 1, but with 5*^^ Joint not longer than 6*^^. Peraeopods 1 and 2,
