Genus Dactylopus Claus. 



1. Dactylopus tisboides Claus.

 188 °- " » G. S. Brady (i), p. 106, pi. liy. figs. 1-16. 



Hob. Between tide-marks, Otago Harbour. 



2. Dactylopus hanseni, sp. nov. (Plate XI. figs. 11-18.) 



Very similar to D. tisboides in general appearance (fig. 11), but rather larger. 

 Antennules of the female (fig. 12) eight-jointed, rather densely setiferous; fourth 

 joint bearing a stout sensory filament. Posterior foot-jaw (fig. 14 a) slender ; hand 

 bearing on each margin a single seta and a fringe of minute cilia ; terminal claw 

 slender, about as long as the hand itself. Terminal claws of the first pair of feet 

 (fig. 15) long and slender, as are also the spines of the outer branch ; penultimate 

 joint of the inner branch bearing near the distal extremity a single small plumose seta. 

 Fifth pair of feet of the female (fig. 18) large, the inner lamina considerably shorter 

 than the outer one ; apex finely ciliated, snbtruncated, and bearing two long and two 

 short setae ; distal extremity of the outer lamina bearing six seta? of various lengths 

 and widely separated, the lateral margins ciliated ; no cilia between the large setae. 

 Length - 85 millim. 



Male. — The antennule (fig. 13) is geniculated, but none of the joints are very tumid ; 

 terminal joint of the inner branch of the second pair of feet (fig. 16) forming two 

 curved finger-like processes, from near the base of which spring two long plumose setae : 

 fifth pair small (fig. 17) ; inner lamina shorter than the outer, with two short spine- 

 like apical setae ; outer bearing six setae, the two apical ones much longer than 

 the rest. 



Hab. Lyttelton Harbour : on algae, 1 specimen ; tow-net at 6 fathoms, 1 specimen. 



The nearest allies of this species seem to be I), cinctus (Claus) and I), stromii 

 Baird, but both of them differ distinctly in minor points. 



Genus Flavia, gen. nov. 



Like Dactylopus, except that the inner branch of the second pair of feet consists 

 of one greatly elongated joint, and is entirely destitute of spines or claws (Plate X. 

 fig. 30). Anterior and posterior foot-jaws simple, prehensile, with long terminal 

 ungues.
