scarcely two-thirds of the length of the eighth joint ; the accessory 

 claws are scarcely half the length of the large claw. 



The length of the body is an eighth of an inch : of the posterior 

 appendages a third of an inch. 



Specimens of this species were obtained with the dredge in Port 

 Stephens. 



Genus. NYMPHOPSIS. Haswell. 



First pair of appendages well developed, cheliform. Second pair 

 well-developed, palpiform with nine joints. Third pair with seven 

 joints, none of them provided with compound spines. 



Nymphopsis armatus, n. sp. 



[PL LV., tigs. 1-4.] 

 The thorax of this species is about three times as long as its 

 greatest breadth, a little narrower behind than in front ; the lateral 

 processes are long, and are separated from one another by tolerably 

 wide intervals ; the last pair are directed much more backwards 

 than outwards, the thorax appearing to bifurcate behind and the 

 two processes thus formed not diverging widely from one another. 

 The abdomen is very long, being more than half the length of the 

 thorax, narrow, cylindrical, armed near the extremity with two 

 powerful acute spines. The ocular lobe is also very long, about half 

 the length of the abdomen with two closely approximated eyes. The 

 proboscis is as long as the thorax ; broad at the base and narrowing 

 a little towards the apex which is truncate. The first pair of 

 appendages extend a very little beyond the extremity of the 

 proboscis ; the first joint is long and narrow, but a little expanded 

 at the extremity where it is produced into a circular rim forming 

 a cup at the bottom of which the second joint is articulated, apices 

 of the fingers extending a little beyond it; this rim is armed with 

 one or two spines ; the fingers are slender, strongly curved, crossing 

 at their tips, and leaving a wide space between when closed. The 

 second pair of appendages ai'e a little longer than the first, slender ; 

 the first joint is short, the second and fourth long, the former being 

 slightly longer than the latter which has a rounded tubercle on
