Flaiihton Crustacea from Neio Zealand. 233 



Podon polyiihemoides (Leuckart). 



Podon polypheuioides, Poppe, Abh. naturvviss. Ver. Bremen, x. p. 298 

 (1889) ; Kriimer, Trans. New Zealand Inst, xxvii. p. 221 (189o) ; 

 Hansen, Cladoceren u. Cirripedien, Plankton-Exp. p. 8 (1899) ; Lill- 

 jeborg, Nova Acta Reg. Soc. Sci. Upt<al. (3) xix. p. 633, pi. Ixxxv. 

 figs. 7-11 (1900). 



Numerous females and a few males are in the collection 

 (hauls 1 A, 1 B, and 1 c). They agree closely with Lilljeborg's 

 description and figures. It is interesting to confirm the 

 occurrence of this sj^ecies in New Zealand waters, since it 

 has not been recorded from any locality nearer than the Gulf 

 of Guinea {Hansen). 



Like the last, this is a " neritic " species, only occurring 

 close to land ; unlike it, however, it is by no means confined 

 to the warmer seas, being found as far north as the Lofoten 

 Islands. 



{b) I SO POD A. 

 Munna sp. 



Three immature female specimens, not exceeding 1"3 mm. 

 in length of body, are in the collection (haul 1 b). They 

 apparently belong to an undescribed species, but in the 

 absence of i'ully adult specimens it seems inadvisable to 

 attempt to diagnose it. The antennules consist of six seg- 

 ments, apart from a very minute and somewhat doubtful 

 terminal segment. The only species recorded from New 

 Zealand is M. neozelam'ca, Chilton *, which has five large 

 segments and two minute terminal ones in the antennule. 

 Chilton's species further differs from the present in its much 

 larger size (3 ram.) and in having the female operculum 

 broadly truncate instead of pointed. 



(c) Ampiiipoda. 

 Paradexamine pacijica (G. M. Thomson). 



Paradcxamine lyacijica, Stebbiug, Das Tierreioh, Amphipoda, 1. Uam- 

 maridea, p. 518 (190(3). 



Numerous small specimens (haul 1 b), none exceeding 

 2*5 mm. in length, a[)pear to belong witliout doubt to this 

 species, which is known from New Zealand and from East 

 Australia.
