42 DR. G. 8. BRADY ON THE 
1. FLAVIA CRASSICORNIS, sp. nov. (Plate X. figs. 26-31.) 
Antennules very short and stout, two-jointed, moderately setiferous (fig. 26). Feet 
of the first pair as in Dactylopus, the terminal ungues thick and hook-like (fig. 29): 
inner branch of the second pair (fig. 30) longer than the outer branch, very slender, 
with truncate unarmed apex; near the base there is on each margin an angular 
prominence, from which springs a minute seta, and near the distal extremity on the 
outer margin a rounded non-setiferous tubercle, nearly opposite to which, from the 
inner margin, arise two long and delicate plumose sete. Anterior foot-jaw simple, 
elongated, with a slightly curved terminal unguis (fig. 27); posterior somewhat 
similar, the hand armed with a long slender marginal spine and a strong curved 
terminal unguis (fig. 28). 
A single specimen of this species occurred in a gathering from among alge in 
Lyttelton Harbour. The posterior antenne, mandibles, and maxille were not seen 
distinctly enough to permit of their being figured, but in general conformation are 
similar to those of most Harpacticide. 
Genus Puroso, gen. nov. 
Body slender ; in general appearance like Canthocamptus. First four pairs of feet 
with both branches three-jointed ; feet of fifth pair foliaceous, unbranched. Internal 
branch of antenne two-jointed. Mandible strongly toothed, palp two-branched. 
Anterior and posterior foot-jaws simple, with large terminal ungues and no palp. 
1. PHROSO GRACILIS, sp. nov. (Plate XI. figs. 19-27.) 
Female.—Antennules eight-jointed, rather densely setiferous ; first four joints stout, 
last three much more slender (fig. 20): lengths of the joints as in the following 
E84 DINO Ee 
T2293 5 5 2) Pb 
Antenne (fig. 21) nearly as large as the antennules, three-jointed ; to the basal joint is 
attached a two-jointed internal branch. Mandibles well developed (fig. 22), with sharp 
slender teeth and a palp composed of a large basal joint and two single Samed branches. 
Maxille (fig. 23) small, lobose (imperfectly seen), Anterior foot-jaw (fig. 24) slender, 
simple, geniculated, with a stout terminal unguis and three plumose sete attached to 
the second joint. Posterior foot-jaw (fig. 25) larger than the anterior, composed of a 
single stout joint which bears a long falcate, terminal unguis, Basal joint of the fifth 
pair of feet (fig. 27) short and broad, and bearing on each lateral angle a long seta; 
terminal joint subovate, twice as long as broad ; apex narrow and truncate; external 
formula ; from the fifth joit arises a stout sensory filament. 
margin ciliated above, and below the middle having two long widely separated sete. 
Length 1:3 millim. Male unknown. 
Hab. One specimen taken in the surface-net, Port Chalmers.
