Remarks. Of these specimens of Pallas' widely distributed species the largest 

 measures 30 mm. by 4 mm., and the smallest 1 1 mm. by 2 mm. including the feet. They 

 are at once distinguished from Fauvel's Eurythoe laevisetis from St Thomas Island, 

 Gulf of Guinea, by the presence of harpoon-shaped chaetae in the dorsal branch of 

 the foot. E. complanata has already been recorded from Annobon by Augener (1918, 

 p. 88). Gravier's account of this species (as E. alcyonia) is probably the most complete.
