a series including both the Eudoxid and polygastric generation of 

 Cuboides vitreous Quoy and Gaimard, originally taken near the 

 Straits of Gibraltar ; a series of the nearly circumtropic Hippo- 

 podium hippopus (Forskal) and representatives of the widely dis- 

 tributed Agalma okeni Eschscholtz. 



The comparatively rare Amphicaryon acavle Chun is repre- 

 sented by a single colony from the "Alva" deep-sea station in the 

 Pacific Ocean, north of Nuka Hiva Island, Marquesas Islands, 

 depth 150 fathoms. Likewise a series of specimens of Abylopsis 

 tetragona (Otto) was taken here. 



A new locality was established for the widely distributed 

 Diphyes bojani (Chun) by the netting of a series of specimens in 

 the Flores Straits, in a depth of 140 fathoms. 



The several specimens of Porpema prunella (Haeckel), also 

 taken in the Pacific north of Nuka Hiva Island, give the third 

 record of this curious species, from a point intermediate between 

 the widely separated type-locality, in the Pacific, north of New 

 Guinea, established by the "Challenger" and the more recent 

 "Albatross" record of it from the tropical eastern Pacific, off the 

 west coast of Peru. 



Scyphomedusae 



The Scyphomedusae collection of the "Alva" World Cruise, 

 1931-32, contains only five species, but includes in these the 

 remarkable, gigantic Versura palmata Haeckel. Four of these 

 species are members of the Rhizostomae, two of which, Versura 

 palmata Haeckel and the exquisite small Mastigias papua (Lesson) 

 were taken in Banka Straits, oif Muntok Island, The specimens of 

 Versura palmata are much the largest recorded of this magnificent 

 species and are apparently the only specimens of it in an American 

 museum. 



Cephea cephea (Forskal) from the Pacific Ocean, north of the 

 Marquesas Islands, is represented by a valuable series of young 

 specimens, which establish a new locality for the species and the 

 second deposit of it in an American museum. 



Stomolophum meleagris (L. Agassiz) from Conway Bay, Gala- 

 pagos Islands, is of exceptional interest, since it is the first record 

 of an adult from this Archipelago, from which locality Haeckel 

 (1880) described a solitary larval specimen. The species, rather 

 scarce on the West Coast of the Americas, and more abundantly
