Book Description
Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

The Development of the Larval Pigment Patterns in Triturus alpestris and Ambystoma mexicanum

Book Description
In the animal world, pigments and colour pigment patterns play an important role. Pigments in the epidermis offer protection against solar radiation, and the various colour patterns provide the animals with concealment, advertisement and disguise (Cott 1940). The study of pigment cells and colour patterns is a multidisciplinary research field which includes developmental biology (determination, differenti ation, migration), genetics (phenotypic gene expression, colour mutants), cell biology (ultrastructure, organelles, cell surface), biochemistry (enzymes, metabo lism), physiology (control of colour changes) and dermatology, as well as ecology and evolution. In the present study we investigate the development of two different amphibian larval pigment patterns. These patterns might serve as specific models for the arrangement of cells derived from the neural crest (NC), involving their migration, differentiation and interaction with each other and the embryonic environment. Because of the NC origin of pigment cells, we consider first some general aspects of NC development, before turning to pigment cells and specific problems in pigment pattern formation. The NC arises during neurulation, an early process in vertebrate embryoge nesis. In amphibians, the crest lies on top of the neural tube as a flat epithelial sheet or strand of cells (Detwiler 1937; Schroeder 1970; L6fberg and Ahlfors 1978; Spieth and Keller 1984). Here the term 'crest' is much more appropriate than in birds or mammals (Newgreen and Erickson 1986), where the crest cells start to migrate before a true crest has formed.
