tioii, however, convinced me that not only was the local species different 

 from either of the described species of Pleustes, but that it also differed in 

 generic character, though only to a small extent. Later on I obtained a 

 second form allied to the first, and to include both these I have formed the 

 genus Panoplcea, so named from the coat-of-mail which envelopes the first- 

 discovered form. The genus differs from Pleustes, in having a well- 

 developed squamiform plate on the ischium of the maxillipeds, and in the 

 gnathopoda being slender, and more or less chelate. The general appear- 

 ance of the animals comprising this genus is also very different. 



The following is the generic character : — 



" Coxffi of the four anterior segments well developed, those of the 

 second pair excavated on the upper part of the posterior margin. Antennae 

 subequal, without a secondary appendage. Mandibles with an appendage. 

 Maxillipeds with a squamiform process on the ischium. Gnathopoda 

 feeble, almost chelate. Three posterior pairs of pleopoda double-branched. 

 Telson simple, squamiform." 



1. P. spinosa. G. M. Thomson (loc. cit., p. 3, 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 pro- 

 duced posteriorly into two spines. Coxte of the gnathopoda narrow, but 

 deep. Eyes reniform, pale reddish in colour. Suj^erior antennfe longer 

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

 ischium and carpus long, propodos with a mobile finger articulating at some 

 distance from the setose extremity ; second pair nearly chelate, bases 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 base 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 fr-om hght to dark brown, thickly covered with black 

 stellate markings. Length 0-45 inch. 



Hah. Taken abundantly with the dredge in Dunedin harbour in 4-5 

 fathoms, among kelp and sertularians. 



2. P. dehilis, G. M. Thomson (loc. cit., p. 3, pi. L, fig. 3). 



Coxfe less developed than in P. spinosa. Pereion tumid ; pleon slender, 

 its first two segments and last of pereion produced on their postero-dorsal 

 margins into spines. Cephalon produced into a very short rostrum. Eyes 

 circular, black. Superior antennte nearly as long as the body, rather 

 longer than the inferior ; peduncle very short. Gnathopoda feeble, sub- 

 chelate ; first pair small, basos long, fringed with a row of short spines on
