GEOGRAPHICAL DISTRIBUTION. 



Despite the great additions to our knowledge of the two families of 

 serpent-stars, we are scarcely yet in a position to do more than hint at 

 the faunal distribution of the species. There is, so to speak, a fauna 

 of the North Atlantic, whereof the extreme Umits are from the Medi- 

 terranean, on the east, to Cape Cod, on the west. The A^nj^hhira squa-

 rohiista, O. Sarsil, and O. nodosa are common to the two sides of the 

 Atlantic, as well as Oj^hiocwifha sjnnulosa ; while Ophiofhrix rosula,
