MARINE COPEPODA OF NEW ZEALAND. 45 
 foot-jaw and fifth pair of feet. The manus of the second pair of foot-jaws (Pl. LX. 
fig. 29) is ovate, elongated, the anterior margin fringed with a continuous series of 
short setz ; terminal unguis long and slender. Feet of the fifth pair (Pl. XII. fig. 14) 
stout, simple, with truncate apex, which bears three short, stout, and very blunt spines, 
the outermost of which is attached at a little distance from the apex: the inner 
margin bears beyond the middle a single seta; the outer margin has also a single seta 
much nearer the base, and is slightly pubescent between that point and the apex. 
The shell is extremely hard and thick, and closely beset with small circular puncta. 
Colour dark brown. Length ‘85 millim. 
Hab. Taken in the surface-net, Port Chalmers and Otago. 
Subfamily IpY1Nn &. 
Genus Ipya Philippi. 
1. Ipya rurcata (Baird). 
Tisbe furcata Claus, Lilljeborg. 
Canthocamptus furcatus Baird. 
Tdya furcata Boeck, Brady, Thomson. 
On alge in Lyttelton Harbour. “Common in shore-kelp and rock-pools near 
Dunedin ; also on kelp in Paterson’s Inlet” (Zhomson). 
Genus ScuTeLLipIuM Claus. 
1. ScUTELLIDIUM PLUMOSUM, sp. noy. (Plate XII. figs. 16-21, 23-25.) 
In general form and appearance indistinguishable from the British S. tishoides. 
The setose investiture of the first foot (fig. 20) is, however, more dense, and the 
spinous armature of the last joint of the outer branch of the swimming-feet (fig. 21) 
is also different, there being on the outer margin towards the apex two plumose 
lancet-shaped spines with intermediate small hairs, while in S. tisboides (fig. 22) there 
are three stout, non-plumose, dagger-shaped spines with no intermediate hairs. Fifth 
foot in the female (fig. 25) elongated, slender, subcrescentic, pointed at the extremity, 
with setose margins, but not pubescent on the surface; in the ma/e (fig. 23) small, 
subquadrate, with obliquely truncated apex, which bears three long and several 
shorter sete. The antennules in the male are geniculated (fig. 16): from the second 
joint springs a small biarticulate peduncle, which bears three stout sensory filaments, 
and to the antepenultimate joint is attached a much longer and stouter sense-organ. 
Length ‘88 millim. 
Hab. This species occurred sparingly in surface gatherings from Otago and Port 
Chalmers, and in gatherings from seaweeds in Akaroa and Lyttelton Harbours.
