the origins of the legs being placed close to one another. The 
last joint of the abdomen is not much produced, but pointed. 
Oviferous legs are moniliform, the last joint armed with a 
straight claw or spine. 
Hab.—German Ocean. 
Genus IV. Nymphon. 
Species 4. Nymphon Johnstonii (mihi).* Body granular : legs 
smooth, without spines or hairs, except at the distal extre- 
mity of the second tarsal joint, which is armed with a fringe 
of strong spines: oculiferous tubercle projecting consider- 
ably above the eyes. 
The whole animal is of a straw-colour, except the claws at 
the extremities of the mandibles, and the edges of the oral 
aperture, which are black. The rostrum is longer than the 
first joint of the mandibles. The oculiferous tubercle is situ- 
ated on the posterior edge of the cephalo-thoracic segment of 
the body, and projects considerably backwards: the eyes, in- 
stead of being arranged on its summit, being arranged around 
its sides. The legs are slender, a deep sulcus runs along the 
sides of each of them, beginning at the proximal extremity of 
the thigh, and ending at the distal extremity of the second 
tarsal joint. The second tarsal articulation is armed with a 
fringe of strong spines, which are situated in a line above the 
auxiliary claws, and cover the bases of the latter. The abdo- 
minal segment is prominent, and the anal aperture is very 
distinctly seen in it. Length of the body two lines: span of 
the legs two inches and three quarters. 
Hab. German Ocean. 
Species 5. Nymphon pellucidum (mihi). Animal slender, pel- 
lucid: body without spines : legs armed with spines placed 
at regular intervals, patent on the second tibial joint, third 
coxal joint about half as long as the first, second tibial 
very long and slender: auxiliary claws strong: abdomen 
prominent, extremity bifid.; 
Hab. Firth of Fort . 
Species 6. Nymphon minutum (mihi). Animal slender, pel- 
* JT have named this species after Dr Johnston of Berwick—a naturalist 
who has done much to elucidate the natural history of this family of Crus- 
tacians.
