Die tierwelt der nord-und ostsee

TLDR: An account—systematic, biological, ecological—of the fauna of the North Sea and the Baltic, and is expected to be completed in about 2000 pp.

Abstract: THE series of which this forms the first section is planned to give an account—systematic, biological, ecological—of the fauna of the North Sea and the Baltic, and is expected to be completed in about 2000 pp. in three years. Each part deals with one group of animals, is separately paged, and bears a number in Roman figures and a letter, so that eventually all the parts with the same Roman figure can be placed together and bound in the sequence indicated by the letters; e.g. all the parts on Ccelenterata will be headed “III.” followed by one of the letters a-f according to the class or order—the part on Ctenophora will be marked “III. f.”Die Tierwelt der Nord- und Ostsee.G.
