G. M. Tuomson.—On the New Zealand Copepoda. 111 
The anterior antenne in the male have the third and fourth joints some- 
what swollen and bent, a character specified by Claus, though it is not as 
distinctly shown in his figures as in the specimens examined by me. The 
secondary branch of the posterior antenne is stated by Claus to be 4-jointed, 
while Brady considers it to be 1-jointed, though he admits that in some 
specimens it appeared to be very indistinctly 4-jointed. I should say the 
four joints were present, but they can only be made out by a high-power objec- 
tive of good definition. The terminal joints of these antennse are furnished 
with six sete (of which four are long and geniculated), and two short pectinate 
spines. The mandibles terminate in four rather blunt apical teeth. There 
appears to be no essential difference between the fifth pair of feet in either 
sex; the figures of this organ in both Claus’s and Brady’s works are 
slightly different from mine. The same remark applies to a certain extent 
to the figures of the entire animal, as well as of the first pair of legs, but 
the differences are so slight, that I have not the slightest doubt of the 
correct identification of our species with the European one. 
Originally described from specimens found at Nice in the Mediterranean; 
also found (but sparingly) in tide-pools, among Laminaria, etc., on the 
British coasts. 
‘Hab. It occurs abundantly among seaweed, in rock-pools, ete., both in 
Otago Harbour and along the ocean beach, Dunedin; also on kelp in Pater- 
son Inlet. 
Fam. ARTOTROGIDA, Brady. _ 
Body broad, depressed, rounded or subovate, composed of 10-12 seg- 
ments, first segment very large, and composed of the coalescent cephalic 
and first thoracic somites, abdomen short, distinctly separated from the 
cephalothorax. Anterior antenne short, 9-20-jointed, alike, or nearly alike 
in both sexes; posterior short, 8-4-jointed, secondary branch (when pre- 
sent) 1-jointed. Mouth produced into a siphon composed of the elongated 
labrum and labium; mandibles stilet-shaped, simple or provided with a 
slender, filiform palp; maxille usually 2-branched and setiferous; first 
and second pairs of foot-jaws simple, prehensile, 2-4-jointed, usually clawed 
strongly at the apex. First four pairs of feet usually 2-branched, each 
branch 2- or 8-jointed. Fifth pair small and 1- or 2-jointed, or altogether 
wanting. 
Genus Conostoma, n. gen. 
Body flattened, broadly ovate; abdomen very short. Anterior antenne 
few- (about 9-) jointed; posterior 4-jointed, secondary branch wanting. 
Mouth siphon rather slender and short. Anterior foot-jaws 2-, posterior 
4-jointed. Feet of the first pair with both branches only 2-jointed; next 
three pairs almost similar. Fifth pair rudimentary.
