LOPHOPHORUS. 121 



appear to have been observed by any other continental 

 author. Its characters are, however, very distinct, 

 especially as to the short 6-jointed antennae and the 

 laminated subtriangular fifth feet ; and I do not 

 doubt that when the proper localities are searched 

 it will be found generally distributed round the 

 European shores. 



Genus 5. LOPHOPHORUS,* nov. gen. 



Anterior antennae (PL XIII, fig. 1) short and stout, 

 8- (?) jointed ; posterior (fig. 2) simple, 3-jointed. 

 Mandibles (fig. 3) dilated at the extremity, strongly 

 toothed, and provided with a 2-branched palp (fig. 4), 

 the primary branch of which is 3-jointed ; secondary 

 branch short, 1 -jointed, and attached to the basal 

 segment, which is much the longest of the three. 

 Maxillge (fig. 5) powerfully toothed and bearing three ex- 

 panded branchial plates. First foot-jaw (fig. 6) stout, 

 the last two or three joints armed with strong curved 

 spines ; second foot-jaw (fig. 7) very stout and robust, 

 otherwise somewhat like that of Cyclops. First four 

 pairs of swimming feet (fig. 8) 2-branched, the branches 

 3-jointed ; fifth pair foliated (fig. 9), bearing a strong 

 resemblance to those of many Harpactidae.
