'812 COLLECTIONS FROM MELANESIA.numerous generic divisions proposed by him would doubtless requireconsiderable modification in any general systematic arrangement ofthe group. Of the numerous Australian additions to this Orderdescribed by Haswell, but few are in the collections received fromDr. Coppinger,1. EpMppiphora kroyeri, White.Several small specimens from Dundas Straits, 17 fms. (No. 161),one from Prince of AVales Channel, 7-9 fms., and one from PortDenison, 4 fms. (No. 122), are referred to this species. They agreewith White's much larger types in the form of the body, the coxaeof the thoracic legs, and particularly in the great development of thepostero-lateral lobes of the fourth coxae, in the broadly roundedbasus-joints and somewhat dilated ischia of the three posterior legs,and in other points. White's examples (from Tasmania) are dried,and the first and second legs are now l)roken, as also the terminalsegment in both specimens. In the specimens from the ' Alertcollection the terminal segment is elongated, narrowing slightlyto the distal extremit)-, with the sides straight, and is divided bya narrow median fissure ; the imperfect terminal segments inWhite's types seem to show a similar structure ; in this particularthey differ from L. nitens, Haswell, from Port Jackson. L. australiensis,Haswell, has a very close resemblance to L. kroi/eri, and Ishould have considered it identical with it, were it not for the probabledifference in the form of the terminal segment, since L. australensisis only distinguished by Haswell from L. nitens by the formof the eyes and the palms and fingers of the second legs.In the present uncertainty as to the true limits of the genera ofthis group, I refer to this species under White's original designationEjphijypiphora. By Boeck this genus is doubtfully considered to beidentical with his Socarnes, first described in 1870.Mr. Thomson* i-ecords the species from Dunedin, New Zealand(as Lysianassa tcroi/eri) ; but as he says nothing of the form of thetelson or terminal segment, I am not sure of the identity of hisspecimens with the true kroyeri.2, Leucothoe spinicarpa, var. commensalis.Gammarus spiuicarpus, Ahildffaarrl, Zool.
