Three species of Antedon were obtained by the naturalists of the »Varna«, together with a couple of Pentacrinoids, the specific identity of which is a little doubtful. Two out of the three, Ant. Eschrichti and Ant. quadrata, are the most widely distributed of the Arctic Comatulae, and extend southwards into the North Atlantic as far as Lat. 45° N.; but the third, Ant. prolixa, had only been previously obtained in Smits’s Sound, 10° farther north, by the British Arctic Expedition of 1875—76.
