Genus: OPHIOTHELAVerrill 

 Ophiothela danae Verrill 



Plate 50 



Type : The type series v^as secured in the Fiji Islands, in large 

 numbers, on Melitodes virgata Verrill (Melitodes ochracea Dana) , 

 by Prof. J. D. Dana, of the United States Exploring Expedition. 

 The depository is not stated, but a part of the material is in the 

 Museum of Comparative Zoology, Cambridge, Mass., and a part 

 very probably is in the Philadelphia Academy of Sciences. 



Distribution: This remarkable little Ophiuroid, most fre- 

 quently found commensal in corals, or on the spines of echinoids, 

 has a wide geographical distribution. Bathymetrically, it is 

 known from the shore line down to 100 fathoms. It has been 

 recorded from the Arabian coast of the Red Sea (Koehler), east- 

 ward to Puri, Orissa, India, on the Bay of Bengal, 10 fathoms, 

 (Koehler) and at Singapore (Turneretscher) , northward in the 

 Formosa Straits (Lutken, Lyman), and the Korean Seas (Dun- 

 can) , and numerous specimens clinging to Melitodes sp., Moroiso, 

 Misaki, in 5 to 10 fathoms and more from off Misaki, Japan, which 

 appears to be the northernmost record for 0. danae (Matsumoto) . 

 Southward it is known from the Philippines between Burias and 

 Luzon and at four other "Albatross" stations in the Sulu Sea, in 

 depths from 18 to 24 fathoms and also from numerous "Siboga"
