is similar to the first, except as regards the endopod, which bears the male appendages ; 

 these appendages are narrow, longer than the endopod, and widen slightly beyond its 

 extremity, and then narrow again to the narrowly rounded apex. The third pleopod 

 has the exopod oval, as in the preceding pleopodo, but slightly shorter than the 

 broadly triangular endopod, both consisting of one joint only. The fourth pleopod 

 has the endopod provided with transverse folds, the exopod with outer margin fringed 

 with numerous short setae and the transverse folds rather poorly developed on the 

 inner half only. The fifth pleopod is similar in general shape to the fourth, but has the 

 exopod 2- jointed and bearing the squamous protuberances as usual. The exopod 

 is mainly opercular, and bears only a few poorly developed transverse folds on a 

 rounded lobe of the inner margin near the base.

Recorded by Mr. Hodgson from the Auckland Islands from specimens collected 

 by the " Southern Cross." In his report on the Isopoda collected by the National 

 Antarctic Expedition Mr. Hodgson records this species from Cape Adare, and gives 

 a full description of it. It was originally described from specimens from South 

 Georgia, and the French Antarctic Expedition of 1903-5 took it at Booth Wandel 

 Island, and at Wincke Island, Flanders Bay. The species has therefore a wide 

 range in subantarctic seas, and, according to Mr. Stebbing, is probably identical 

 with Cymodocella {Sphaeroma) algoense, Stebbing, 1875, from Algoa Bay, South 

 Africa.
