Excerpt from Normal Plates of the Development of Necturus Maculosus Dorso-lateral view of embryo 20 days 10 hrs. Old, length 6 mm, 6 pairs of myotomes. Outline of body conforms to curvature of egg. Head end of embryo shows three longitudinal ridges; middle ridge lies slightly above level of lateral ridges. The middle one is common anlage of fore, mid and hind brain. The lateral ones are the common anlage of the optic vesicles and branchial arches. Anus formed. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from Normentafeln Zur Entwicklungsgeschichte Der Wirbeltiere, Vol. 10: Normal Plates of the Development of Lepidosiren Paradoxa and Protopterus Annectens Conspicuous features in these stages are the cement organ a crescentic structure on the ventral side and the external gill rudiments situated on visceral arches III - VI. About stage 23 in Lepidosiren a vascular network is seen over the surface of the yolk, its cavities filled with colourless blood there being for some time after its appearance no haemoglobin present. About the time of hatching (stage 27) the larva has a somewhat tadpole-like shape the hinder tail ]ike region of the trunk being flexed ventrally. In Protopterus a larger proportion of the yolk is con centrated in the anterior swollen part which as a consequence bulges more prominently and the rudiments of various organs external gills and eyes are also seen to be relatively larger than in Lepidosiren. Within a short space of time after hatching (stage 28) the trunk becomes straightened out and the pinnae of the external gills appear as two rows of little knobs on their external surface. The myotomes are seen to be growing actively in dorsiventral direction. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

As scientific analysis of testable hypotheses has replaced the speculative approach to study of bone disease in recent and fossil amphibians and reptiles, the field has advanced from simply reporting observations to analyzing their implications. This process is predicated upon a reproducible data base which explains/diagnoses the nature of bony alterations and a secure review of the literature. Thereby hangs the rub. The herpetological literature are difficult to access (let alone read) and are scattered through many prominent and eclectic journals and in the lay literature. While older diagnoses often have not stood the test of time, the clarity of report descriptions usually allows confident identification of the underlying pathology.

A discussion of the neural crest and neural crest cells, dealing with their discovery, their embryological and evolutionary origins, their cellular derivatives - in both agnathan and jawed vertebrates or gnathostomes - and the broad topics of migration and differentiation in normal development. The book also considers what goes wrong when development is misdirected by mutations, or by exposure of embryos to exogenous agents such as drugs, alcohol, or excess vitamin A, and includes discussions of tumours and syndromes and birth defects involving neural crest cells.

Comparative Vertebrate Neuroanatomy Evolution and Adaptation Second Edition Ann B. Butler and William Hodos The Second Edition of this landmark text presents a broad survey of comparative vertebrate neuroanatomy at the introductory level, representing a unique contribution to the field of evolutionary neurobiology. It has been extensively revised and updated, with substantially improved figures and diagrams that are used generously throughout the text. Through analysis of the variation in brain structure and function between major groups of vertebrates, readers can gain insight into the evolutionary history of the nervous system. The text is divided into three sections: * Introduction to evolution and variation, including a survey of cell structure, embryological development, and anatomical organization of the central nervous system; phylogeny and diversity of brain structures; and an overview of various theories of brain evolution * Systematic, comprehensive survey of comparative neuroanatomy across all major groups of vertebrates * Overview of vertebrate brain evolution, which integrates the complete text, highlights diversity and common themes, broadens perspective by a comparison with brain structure and evolution of invertebrate brains, and considers recent data and theories of the evolutionary origin of the brain in the earliest vertebrates, including a recently proposed model of the origin of the brain in the earliest vertebrates that has received strong support from newly discovered fossil evidence Ample material drawn from the latest research has been integrated into the text and highlighted in special feature boxes, including recent views on homology, cranial nerve organization and evolution, the relatively large and elaborate brains of birds in correlation with their complex cognitive abilities, and the current debate on forebrain evolution across reptiles, birds, and mammals. Comparative Vertebrate Neuroanatomy is geared to upper-level undergraduate and graduate students in neuroanatomy, but anyone interested in the anatomy of the nervous system and how it corresponds to the way that animals function in the world will find this text fascinating.

“Authoritative and comprehensive—provides an up-to-date description of the tool box of methods for inventorying and monitoring the diverse spectrum of reptiles. All biodiversity scientists will want to have it during project planning and as study progresses. A must for field biologists, conservation planners, and biodiversity managers.”—Jay M. Savage, San Diego State University “Kudos to the editors and contributors to this book. From the perspective of a non-ecologist such as myself, who only occasionally needs to intensively sample a particular site or habitat, the quality and clarity of this book has been well worth the wait.”—Jack W. Sites, Jr.
