Boone, Mollusca, Cruises of ''Ard" arid "Alva" 287 



The "Alva" World Cruise obtained several specimens of Sepioteu- 

 this mauritiana Quoy and Gaimard in Noumea, New Caledonia, 

 establishing a new distribution record for this species, which 

 greatly extends its geographic distribution. So far as published 

 records show, S. mauritiana appears to be absent from the collec- 

 tions of American museums. 



Larval forms of the exquisite little Oegopsid, Abraliopsis mori- 

 sii (Verany) from Flores Straits and of the sea-arrow, Omma- 

 tostr-ephes sagittatus (Lamarck), from off Canary Islands, were 

 secured. An extensive series of Onychoteuthis banksii Leach 

 was taken by the "Ara" in the Sulu Sea, off the Zamboangan 

 coast of Mindanao. 



The rare Sepia rouxii d'Orbigny was taken in series by the 

 "Alva" in Georgetown, Penang, Malay Straits. The largest of the 

 Mediterranean Sepiidae, Sepia officionalis Linne was taken at 

 Naples, by the "Alva" Mediterranean Cruise. 



The rare and exquisite little Hawaiian Sepiolid, Euprymna 

 scolopes Berry, was taken in Kewalo Bay, by the "Ara" World 

 Cruise. 



The Octopoda are represented by six species, five of which are 

 members of the littoral fauna of the Indo-Pacific region, while the 

 sixth species is an abyssal octopod from the continental shelf of 

 the southeastern United States. These littoral octopods include 

 the widely distributed Octopus {Octopus) rugosus (Bosc), of 

 which an exceptionally fine series was secured in the Marquesas, 

 the Society Islands, Seba-Seba Bay, Durian Straits and the harbor 

 of Southport, Australia, collected by the "Alva" World Cruise; 

 young forms of Octopus (Octopus) horridus d'Orbigny from the 

 Red Sea; O. (O.) cyanea Gray from Hawaii; 0. (0.) macropus 

 Risso from the Marshall Islands, a locality record of especial 

 interest for this species and the seldom captured O. (0.) ornatus 

 Gould of Hawaii, these last four species being taken by the "Ara" 

 World Cruise. 



The deep-water octopod, Bathypolypus arcticus Prosch, as its 

 name indicates, is an inhabitant of the European and east Ameri- 

 can Arctic waters, known as far south as southwest Ireland and 

 South Carolina. The "Alva" collected two fine specimens off Fowey 

 Rocks, south Florida, in a depth of 100 to 200 fathoms, thus sub- 

 stantially extending the southern range of this bathypelagic 

 octopus.
