FROM THE FALKLAND LSLAXDS. 339 



examination in the year 1918, though the eyes had become orange 

 lather than red. 



Chevrenx in 1913 describes his Stehhiv ykc gracilis as having the 

 liody " teinte de l)lancet de rose" and the eyes " d'un rouge vif." 

 Jt also agrees with our Falkland specimens in having no accessory 

 flagellum 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 

 perseopods ca,nnot be reconciled with the comparatively stout and 

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

 specimens removed from as many different limpiets were found 

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

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

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

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

 species being there named Atijloides ausiralis (Miers).
