the "Alva" World Cruise. The second species is the vermilion 

 Pentaceraster alveolatus (Perrier) , highly interesting in its vari- 

 ability, even as exhibited in the small series obtained by the "Ara'" 

 in Philippine waters. The distribution of these sea-stars is as 

 follows : 



Linckia laevigata Linne, Kaneohe Bay, Oahu, Hawaii. 

 Pentaceraster alveolatus (Perrier), Zamboanga, Philippine 

 Islands. 



Crinoidea 



The Crinoidea are represented by five species, all members of 

 the superf amily Comasterida, three of which were collected in the 

 Dutch East Indies, by the "Alva," as follows : 



Comatula pectinata (Linne), Durian Straits. 

 Comaster gracilis (Hartlaub), Flores Straits. 

 Lamprometra vrotectus (Lutken), Bali. 



The remaining two species were collected in the Anambas 

 Islands, South China Sea, by the "Ara," as follows : 



Comanthus samoana A. H. Clark, 3.2 miles S.S.E. of Pule 

 Telaga Island. 



Amphimetra ensifer (A. H. Clark), 3.2 miles S.S.E. of Pulo 

 Telaga Island. 



Ophiuroidea 



The Ophiuran collection of the "Alva" World Cruise of 1931- 

 32 includes nine genera represented by twelve species from five 

 archipelagoes — the Samoan, Fiji, Society, Palm (Queensland), 

 Bali and Seba-Seba Bay of the Sunda Isles. 



The three species from Ingham Island, Queensland, are each 

 of unusual interest. Amphioda ochroleuca (Brock), hitherto 

 known only from the type, a single specimen taken in Amboina 

 and deposited in the Gottingen Museum, is now represented in 

 the Vanderbilt Marine Museum by three specimens from Ingham 

 Island, which greatly extend the known range of the species. The 

 rare and lovely Ophiactis brocki de Loriol, likewise known only 

 from the type and taken at Amboina and deposited in the Geneva 

 Museum, is here represented by two specimens from Ingham 

 Island and seventeen from the Society Islands, indicating an
