Studies in dipnoan structure

Miller, Agnes E (1962) Studies in dipnoan structure. PhD thesis, University of Glasgow.

Abstract

An examination of certain structures at an early stage in the development of the living Dipnoi is of interest and importance morphologically since this group is one of great antiquity and may on that account he expected to contain certain primitive features. In one genus particularly, Lepidosiren paradoxa, the tissue cells are of very large size and this fact makes for greater clarity in histological investigation than is the case in several other groups which do not possess this advantage. The following thesis deals with work, first of all, on the appendicular skeleton and considers the structure of the pectoral fin skeleton of Ceratodus forsteri and its hearing on the condition met with in certain other primitive vertebrates. The second part of the work concerns the axial skeleton and of this there are two aspects. One of these deals with the arrangement met with in the hinder part of the body of Lepidosiren and Protopterus, the other is an investigation into the origin of the sheaths surrounding the notochord in early stages.
