Excerpt from book: PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON A NEW STARFISH FROM THE MAGELLANIC REGION. BY AUSTIN H. CLARK. The new starfish described below was dredged by the "Albatross " on her voyage from the Atlantic into the Pacific. It represents a type hitherto not known from the Magellanic portion of the subantarctic belt. Family ODONTASTERIDE Verrill. Odontaster proplnquus new species. Five arms; R=29mm.; r=14 mm.; R:r=2.1:l; superomarginals 17. This form agrees most minutely with 0. elongatui (Sladen) from Kerguelen, Marion and Heard Islands, excepting in having much shorter arms and no pseudopedicellarise. It will probably prove to be a Magellanic variety of that species. Type.? Cat. No. 36,976, U. S. N. M., from "Albatross" Station 2771, off southeastern South America, in 50% fathoms.

BY WILLIAM HEALEY DALL. Among some alcoholic specimens collected by the' 'Albatross'' at the Galapagos Islands in 1887-8, were two small specimens belonging to the section Naesiotus which were overlooked at the time of Dr. Stearns' report of 1893. Being engaged on a report on a collection made during the California Academy of Sciences Galapagos Expedition of 1905-6, it seemed proper to describe the above mentioned species in order that they might be included in the general summary of the landshell fauna. Bulimulus (Naesiotus) saeronius n. sp. Shell very small, smooth, short-conic, the last whorl much the largest, five-whorled, the apex dimpled, the apical whorl delicately transversely striated, the suture deep, widening and becoming channelled on the last whorl;...
