The anterior antennae 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 antennas is stated by Claus to be 4-jomted, 

 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 antennas are furnished 

 with six setae (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. 



Hah. It occurs abundantly among seaweed, in rock-pools, etc., both in 

 Otago Harbour and along the ocean beach, Dunedin ; also on kelp in Pater- 

 son Inlet. 



Fam. ABTOTBOGID^, 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 antennae short, 9-20-jointed, alike, or nearly alike 

 in both sexes; posterior short, 3-4-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 ; rnaxillas 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 3-jointed. Fifth pair small and 1- or 2-jointed, or altogether 

 wanting. 



Genus Conostoma, n. gen. 



Body flattened, broadly ovate ; abdomen very short. Anterior antennas 

 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 pahs almost similar. Fifth pair rudimentary.
