"ENDEAVOUR" SCIENTIFIC RESULTS. 



Stebbing has since suggested the establishment of a new 

 genus, Parawaldeckia, for its inclusion. 



The present specimen, which is a male with greatly elon- 

 gated tiagellum to the second antenna, appears to be quite 

 the same as the type specimen of Lysiannax stcbbingi, 

 G. M. Thomson, which was obtained at Pirates Bay, Tas- 

 mania, and with which I have compared it. In the 

 "Endeavour" specimen the telson (Fig. 8 //) has the pos- 

 terior margin transverse \vith two setules at each posterior 

 angle. Mr. Thomson's type is mounted permanently so 

 that the telson is seen in side view and the posterior border 

 cannot be made out, but it shows the two setules at the

angles as in the "Endeavour" specimens. In Socarnoides 

 hergueleni, Stebbing, which I have considered to be the 

 same as the present species, the angles of the telson bear 

 setules but the margin between is rather deeply indented 

 or cleft. I give also a drawing of the third uropod (Fig. 

 3 a). 



If all the forms I have grouped under the name .V. kidderi 

 are rightly included, the species is widely distributed in 

 Australian and New Zealand seas and in Subantarctic 

 regions.
