6 STALK- AND SESSILE-EYED CRUSTACEA 
are small, sub-equal, the external orbital spine is acute, and the five 
branchial spines form a regular series, and are equidistant. 
4. Paramithrax barbicornis. PII, fig,2. ¢@. 
Pisa barbicornis, Latr. Encycl. x, p. 141, (1825). 
Paramithrax barbicornis, M. Kdw. Hist. Nat. Crust. 1, p. 824, (1834); 
Miers, Ann. Mag. Nat. Hist. (ser. 4) xvi, p. 219, (1876). 
Carapace nearly ovoid, convex reddish livid brown, covered with 
long concolorous, or brown on white hairs. Sides dilated after the 
postocular teeth. Rostral spmes strong, triangular, acute, divergent. 
Orbits deeply notched above, terminated posteriorly by a small spine, 
two other spines after the notch, which are stronger, especially the 
former, which forms the posterior extremity of this part of the orbital 
margin. Four small spines on the sides, of which the two first are 
obtuse, placed near to one another, the two last acute, separated. 
Anterior legs reddish, small, wrists as long as the palms; fingers 
slender, conical, white, acute, without teeth. Ambulatory legs rather 
large relatively to the body, with long yellowish hairs. (Latr.). 
Australia (Mus. Paris); New Zealand (Coll. Brit. Mus.). 
Some specimens from New Zealand, in the Collection of the British 
Museum, are, I think, to be referred to the foregoing species, of which 
the description applies to the young female. The males have the 
anterior legs greatly developed; arm with a series of strong spines 
above; wrist with two ridges, the inner divided into several lamellate 
or tuberculiform lobes, the outer uninterrupted, except at the base. 
Hands compressed; fingers leaving a space at base when closed. 
Carapace, when the hairs are removed, appears covered with numerous, 
wart-like, minutely punctate flattened tubercles. Length, 2 in.; 
breadth, 14 in. 
Should this species, on comparison with specimens of both ages and 
sexes from Australia, prove distinct, it may be designated by the name 
of P. latreillei.
