REPORT ON THE CRINOIDEA. 137 
The four Caribbean species of Pentacrinus are widely distributed among the West India 
Islands; and it is possible (or rather probable) that systematic dredgings among the 
islands of the Pacific, like those of the ‘‘ Blake” in the Caribbean Sea, would largely 
increase the specific range both of Pentacrinus and of Metacrinus. 
Among the Comatulee the well known Antedon eschrichti is universally distributed 
in the Arctic Ocean, and on both sides of the Atlantic as far south as lat. 43° N.; while 
Antedon dentata of the Barents Sea, the north-east Atlantic, and the Scandinavian 
coasts is abundant on the banks off New England. Antedon carinata is another widely 
distributed species, occurring both on the Atlantic and on the Pacific coasts of South 
America, at Java, Mauritius, the Seychelles, and elsewhere; while Actinometra pulchella of 
the Caribbean Sea has also been dredged in moderately deep water off the coast of Morocco. 
The greater number of the Comatulee, however, like the four species of Bathycrinus
