Crustacea from New Zealand. 3 



I have formed this genus to include two species which 

 appear to me to be the southern representatives of the Arctic 

 genus Pleustes. It differs from Pleustes only in the well- 

 developed squamiform plate on the ischium of the maxillipeds, 

 and in the gnathopoda being slender and more or less chelate. 

 In the general appearance of the species, however, there is 

 a very perceptible difference. 



1. Panoploea spinosa, n. sp. (PI. I. fig. 2.) 



Cephalon produced into an acute rostrum. Pereion broad, 

 smooth, the dorsal margins of the last segment and of the 

 first two of the pleon produced posteriorly into two spines. 

 Coxae of the gnathopoda narrow, but deep. Eyes reniform, 

 pale reddish in colour. Superior antennae longer than the 

 inferior. Both pairs of gnathopoda very slender : first chelate, 

 ischium and carpus long, propodos with a mobile finger arti- 

 culating at some distance from its setose extremity ; second 

 pair nearly chelate, basos very long, propodos fringed with 

 simple hairs on its inferior margin, dactylos articulating 

 almost as in first pair. Pereiopoda increasing somewhat in 

 size posteriorly, squamiform plates of the basa of the last three 

 pairs toothed on their posterior margins. Three posterior 

 pairs of pleopoda subequal ; rami of the penultimate pair 

 unequal. Telson subquadrate ; extremity slightly excavate. 



Colour varying from light to dark brown, thickly covered 

 with black stellate markings. Length 0*45 inch. 



Several specimens taken in Dunedin Habour, in 4-5 

 fathoms. 



2. Panophxa debilis, n. sp. (PI. I. fig. 3.) 



Coxae less developed than in P. sjnnosa. Pereion tumid ; 

 pleon slender, its first two segments and last of pereion pro- 

 duced on their postero-dorsal margins into spines. Cephalon 

 produced into a very short rostrum. Eyes circular, black. 

 Superior antennae nearly as long as the body, rather longer 

 than the inferior ; peduncle very short. Gnathopoda feeble, 

 subchelate : first pair small, basos long, fringed with a row 

 of short spines on the anterior margin, propodos long, dactylos 

 small, transverse ; second pair similar in form, but very long 

 and slender. Pereiopoda as in P. spiJiosa, but with the mar- 

 gins of the squamiform plates smooth. Telson rounded at 

 the extremity. Colour uniformly light brown ; when exa- 

 mined under a low power of the microscope the whole body is 

 seen to be dotted with reddish-brown star-like marks. Length 

 0'35 inch. 



Not uncommon in Dunedin Harbour, in 4-5 fathoms.
