XI. — A neio Family of i'rustacea Isopodcx. 

 By George M. Thomson, F.L.S. 



[Plate I.] 



In the ' Mission de File Campbell/ published in 1885, the late 

 Dr. Filliol briefly described (p. 492) an Isopod obtained at 

 Stewart Island as Idotea Stewarti, and figured it at pi. liii. 

 figs. 8 and 9. The following is a translation of the very 

 brief description : — 



"Inner antennae very short, 4-jointed; terminal joint 

 elongated, slightly enlarged in the middle. Its apex reaches 

 the end of the second joint of the outer antennje. The latter 

 are 5-jointed ; iheir lower margin is i'urnished with numerous 

 harsh hairs. The three first pairs of feet increase in size 

 posteriorly ; their third, fourth, and fifth joints are furnished 

 with numerous hairs on their lower margins; the claws are 

 long, slender, recurved, and acute. The last segment is 

 elongated and rounded at its apex.^^ 



Among some Crustacea received from my friend Dr. Chilton, 

 from Mr. 11. Drew of Wanganui, were two dried specimens of 

 this species.
