428 Annals of the South African Museum. 



Female. Head only very faintly crenulate, " limbe posterieur " 

 with margin entire, the lateral processes not creuulate. Eyes not 

 distinguishable. Ovarian bosses on segments 1-4. Maxilliped with 

 inner distal angle of anterior part not so much produced as in Sars' 

 figure, without any indication of a palp. First marsupial plate 

 without posterior process on distal lobe, overlapping ridge well 

 developed ; posterior margin of plates 2 and 3 setulose, of 4 and 5 

 strongly setose. 



In other respects corresponding with Sars' description. 



Length: ? 5mm., $ 2mm.; breadth: $ 3'5 mm., J T5 mm. 



Colour: In spirit dull pinkish. 



Locality : Off Port Shepstone, Natal. 24 fathoms, s.s. " Pieter 

 Faure/' '(S.A.M. No. A4860.) 



Host : Galathea dispersa Bate. In the branchial cavity. 



Geogr. Distribution: Coast of Norway. On Munida rugosa and 

 teniiimana. (Sars.) 



PARAGIGANTIONE n. g. 



Female. Body oval, asymmetrical. Epimera well defined, extend- 

 ing the whole length of the segment, not expanded. Pleon segments 

 distinct. Pleura hiding the pleopods but not expanded, entire. 

 Maxilliped similar to that of Gigantione, without palp. All 7 pairs of 

 peraeopods developed. Pleopods biramous, entire, inner rarnus larger 

 than outer. Uropods biramous, rami subequal, ovate, not pedunculate. 



Male. Peraeou and pleon segments distinct. A median ventral 

 papilla on peraeon segments 1-6. Pleopods present on segments 1-5, 

 lobe-like. Uropods lamellate, uniramous, ovate. 



Parasitic in the branchial cavity. 



This genus differs from Gigantione in having in the ? non-pedun- 

 culate uropods, the segments not expanded and the pleopods not 

 fimbriate or fringed. No mention is made of the ventral papillae of 

 the <$ in any species of Gigantione, so that their absence may be 

 reckoned as a characteristic of the genus. 



The only other genus in which the $ has biramous uropods and the 

 pleon segments of the <$ are distinct is Aporobopyroides Nobili 1906, 

 but in this genus the 5th and 6th pleon segments of the $ are fused 

 dorsally and ventrally and there are no pleopods or uropods. The <$ 

 of Urobopyrus Richardson 1904 is unknown.
