FROM THE FALKLAND LSLAND9. ' 339 



exaiuinntion in the year 1918, thoiigli the eyes had become orange 

 lather than red. 



Chevreux in 1913 describes his Stehh'mgia gracilis as having the 

 body "teinte de blanc et de rose" and the eyes " d'un rouge vif." 

 It also agrees with our Falkland specimens in having no accessoiy 

 Ungellum to the first antenna, and the telson slit for half its 

 length, but the smoothly rounded apex of each lobe is devoid of 

 the spinule which our specimens have, and the slender spinose 

 pei'a3opods cannot be reconciled with the comparatively stout and 

 smooth lower joints of the Falkland species, of which " six more 

 specimens removed from as many different limpets were found 

 later." One of these smaller examples, however, proved to belong 

 to a different genus. As to the Paramcera specimens, so far as 

 I have been able to verify the details, they agree with those 

 which I liave figured in the ' Challenger ' Amphipoda, pi. 76, the 

 pecies being there named Atijloides aash-aUs (Miers).
