8. Hyastenus diacanthus. 
Nawia diacantha, De Haan, Faun. Japon. Crust. p. 96, pl. xxiv, 
fig. 1, (1839). 
Carapace triangular, rather convex. Jostral spines long~ and 
slightly divergent. Gastric region very convex, in young specimens 
almost tuberculated. Antero-lateral margins long, straight, unarmed, 
terminating posteriorly in a strong spine, directed outward, and placed 
on a level with the back of the branchial regions. Anterior legs in 
the male strong, without spines or tubercles, hand rather compressed, 
fingers leaving a slight hiatus at base when closed. First pair of 
ambulatory legs very much longer than the succeeding. The whole 
animal more or less thickly covered with stiff curled hairs. Length, 
24 in.; breadth, 1} in. 
New Zealand (Coll. Brit. Mus.). 
The range of this species extends northward through Port Essington 
and the Philippine Islands to Japan. 
PARAMICIPPA. 
Paramicippa, M. Edw. Hist. Nat. Crust. 1, p, 332, (1834). 
Carapace nearly oblong, inter-orbital space very broad, with a 
depression on each side behind the orbits. Rostrum broad, lamellate 
and deflexed, two-lobed. Eyes obliquely retractile within the narrow 
orbits, which have one or two fissures above and below. Basal joint of 
the external antenne very broad, flagellum visible from above at sides 
of rostrum. Epistome transverse. Anterior legs in the male with the 
palm enlarged, short, smooth, fingers when closed, meeting only at their 
tips. Abdomen of ¢ and 9 seven-jointed. 
This genus is closely allied to Micippa, from which it is far removed 
in Dana’s system of classification ; the orbits are formed upon the same 
plan, and the eyes, I believe, retractile in both genera; the principal 
difference is in the anterior legs, which in Micippa are slender, 
elongate, with the fingers meeting throughout when closed. 
9. Paramicippa spinosa. 
Micippa spinosa, Stimpson, Proc. Acad. Nat. Sci. Philad. p. 218, 
(1857). 
Carapace depressed, unequal above, closely tuberculated and setose. 
Dorsal spines few, long, slender, obtuse at apex, three in the median
