REPORT ON THE ISOPODA. 109 



Studer's description 1 of the species is so sufficient that I need not redescribe it. 

 Station 145a, December 27, 1873 ; lat. 46° 41' S., long. 38° 10' E.; depth, 310

Of the genus Apseudes three distinct species were dredged during the voyage of 

 the Challenger ; one of these is apparently a new species and is described in detail 

 below ; a second species would seem to be identical with Studer's Apseudes spectabilis ; 

 both these species are from Kerguelen ; the third species, from shallow water off Sydney 

 in Australia, I identify with Haswell's Apseudes austrcdis. 



There are not a great number of species of this genus known, and the majority of 

 these are from the European seas ; a remarkable form is Chilton's Apseudes timaruvia 

 from New Zealand; 2 this species differs from all others of the genus by the absence of an 

 exopodite to the antennae and by the similarity of the fossorial limbs to the succeeding 

 thoracic appendages ; it would be interesting to have a little more information respecting 

 this species, which may well, as Mr. Chilton suggests, be the type of a distinct genus. 



The new species from Kerguelen described in the present Report does not present 

 any special features of interest. 



This genus is, so far as is known, confined to shallow water ; no representatives 

 from deep water have been described.

Among the Isopoda obtained at the Island of Kerguelen by the German ship 

 " Gazelle," and figured and described by Studer in his account of the collection's, is a 

 species of Apseudes, named by him Apseudes spectabilis ; during the Challenger 

 Expedition a single specimen of this species was also obtained at Christmas Harbour, 

 Kerguelen, which agrees so closely with Studer's description and figures that I have not 

 deemed it necessary to redescribe this species in the present Report. 



At the same locality, a number of specimens of a smaller species of Apseudes were
