Dr H G Bronn's Klassen und Ordnungen des Tierreichs wissenschaftlich dargestellt in Wort und Bild

Abstract

BAND 6, Abteilung 1 contains accounts of the Lepto-cardii and the cyclostomes contributed by four succes sive authors—Drs. Lonnberg, Favaro, Mozejko, and Rauther, the last named being responsible for this Lieferung 39 which completes the Abteilung. He has contributed the last dozen pages of the description of the urinogenital organs of cyclostomes, a clear account of the development and organogeny of Lampetra and of Bdellostoma and of the biology of the principal species, and a scheme of classification in which the characters of the known genera and species are con cisely stated. A short discussion on variation and similar matters, some general observations on geograph ical distribution, and an appendix on the origin and relationships of cyclostomes, form the concluding part of the text. There is an adequate systematic and subject index. Opportunity might have been taken to refer in the appendix to memoirs by Cole and others which have been issued since the earlier parts of the volume were published.
