5(3 MR. A. O. WALKER ON AMPIIIPODA 



joints of tlie perseopods. From JE. cuspidatus, var. antarcticus, 

 Tliomsoii, it is separated by tte conspicuous dactylus of the 

 maxillipedes. 



Fam. Calliopiid^. 

 Greuus nov. Oeadarea*. 



Body compressed. 



TLird joint of mandibular palp rather shorter and narrower 

 than the 2nd. 



Maxilla and maxillipedes as in Amphitliopsis, G. 0. Sars. 



Upper antennae with a small secondary appendage. 



Lower antennae considerably longer than the upper. 



Gruathopods very unequal, the 2ud much longer and propor- 

 tionately narrower than the Ist. 



Telson entire. 



This genus is very near to Aonjyhithopsis, Boeck, 1870, as 

 restricted by Gr. 0. Sars (' Amphipoda of Norway,' p. 455), but 

 differs in the more compressed body, the narrow 3rd joint of tlie 

 mandibular palp, and the relative inequality of the guathopods 

 and antennae. From Boeck's definition it also differs in the 

 dorsal prolongation of the first two segments of the metasome 

 (Boeck says " Corpus compressum, nee carinatum, nee spinosum "). 

 The greater length of the lower antennae than the upper justifies 

 the placing of this genus in the Calliopiidae even more than 

 Amphitliopsis, but, as G. O. Sars remarks of the latter, botii show 

 considerable aflB.nity with the Paramphithoidae. 



0. LOKGIMANA, U. sp. (PI. 10. figS. 77-89.) 



Cape Adare beach, after gale, April 5, 1899 ; Jan. 17, 1900. 

 Dredged, 8 fath., Jan. 17, 1900. 



Body rather swollen. Segments of mesosome subequal, except 

 the last which is as long as the two preceding. First two seg- 

 ments of metasome in adults dorsallj produced in a sharp tooth ; 

 the 3rd segment has the hind margin straight, but hollowed out 

 just above the acute posterior angle, lower margin convex. 

 TJrosome about as long as the last two segments of the metasome. 

 Anterior side-plates of the mesosome slightly turned outwards, 

 convex. 



Head as long as the first two segments ; rostrum very short, 

 acute. Eyes not discernible.
