• On muddy bottoms in the Andaman Sea some small and rather damaged 

 specimens of two species of Comatula? were trawled. These were Eudiocrinus 

 (i.e., Pentametrocrinus) from 922 fathoms, and Antedon (?)— a ten-armed species

ANTEDON BIFIDA. 



Antedon bifida 189:3. Bell, Cat. Brit. Echinoderms in Brit. Mus. (1892), p. 56. 



Professor Bell, in discu.ssing the distribution of Antedon bifida, says : •' If the 

 last views of Carpenter (Journ Linn. Soc. xxiv (1891), p. 68) are correct this pro- 

 tean specie.s [i.e. Antedon bifida] is represented off Bengal, for it would appear 

 that A. duebeni is probably a synonym." 



The author intended to say Brazil ; A ntedon dilbenii was described from Rio 

 de Janeiro and has not been found elsewhere.
