No doubt tbe word " accessorii " is applied to tbe flagellum of the lower antennae in the above 

 account by an accidental mistake in writing.

The observations refer to the Crustacean fauna of Dunedin Harbour, the maximum depth of 

 the bay being probably about 6 fathoms. Under "Amphipoda Normalia. Fam. Gam- 

 maridse. Subfam. Stegocephalides." there is instituted the new genus Panoplcea, thus 

 defined : — 

 " Coxae of the four anterior segments well developed, those of the second pair of pereiopoda 

 excavated on the upper part of the posterior margin. Antennaj 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." Mr. Thomson says, " 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 weU-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." The new species, figured PI. I. figs. 2, 3, are named PanojUoea spinosa and 

 > PanopUta dehilis. Of these, through the kindness of Mr. Thomson, I have been able to 



examine specimens, and it appears to me that Panoploea spinosa is certainly an Ipliimedia, 

 while Panoplosa dehilis has numerous points of resemblance to Amphithopsis longimana, 

 Boeck, but as the species has three dorsal spines, it may be more correct to place it in the 

 closely allied genus Halirages, Boeck. It cannot be generically united with Panoploea 

 {Iphimedia) spinosa. In " Subfam. Phoxides. Genus Amphilochus, C. Spence Bate," is 

 described " Amjjliiloclms squamosals, n. sp. (PI. I. fig. 4.)." In "Subfam. Gammarides. 

 Genus Eusirus, Kroyer.,"is described "Eusirus euspidatiis, Kroyer, var. antardieus, n. var." 

 Of "Melita tenuicornis, Dana {Mcera tenuicm-nis, Sp. Bate, Paramosra tenuieomis, Miers)," 

 it is said, "the females are remarkable for possessing a hook-like process on the coxal 

 lamellae of the fourth pair of pereiopoda, almost exactly similar to that figured and described 

 by Fr. Miiller (Facts for Darwin, p. 27) as occurring in At. insafiahilis." In "Genus 

 Megamoera, Spence Bate," " Megamoera fasciculata, n. sp. (PI. I. fig. 5), is described. 

 In "Fam. Corophiidae. Genus Corophium, Latr." a description is given of Gorophium 

 contractum, Stimpson.
