Reptiles - Part V - The Zoology of the Voyage of H.M.S Beagle

Thomas Bell, Charles Darwin

Description

First published in 1842, this vintage book contains part five of Charles Darwin's “The Zoology of The Voyage of H.M.S. Beagle”, a fascinating and detailed account of the research he did whilst aboard the HMS Beagle between 1832 and 1836—work that played a key role in the conception of his scientific theories on evolution and natural selection. This part concentrates on the reptiles and amphibians that he encountered and studied around the world. Contents include: “Alsodes Monticola”, “Amblyrynchus Cristatus”, “Ameiva Longicauda”, “Borborocaetes Bibronii”, “Bufo Chilensis”, “Centrura Flagellifer”, “Cyclodus Casuarinae”, “Cystignathus Georgianus”, “Diplolaemus Bibronii”, etc. Charles Robert Darwin (1809 – 1882) was an English geologist, naturalist, and biologist most famous for his contributions to the science of evolution and his book “On the Origin of Species” (1859). Many vintage books such as this are increasingly scarce and expensive. We are republishing this volume now in an affordable, modern, high-quality edition complete with the original text and artwork.

PREFACE.
A MONGST the Reptiles and Amphibians obtained by Mr. Darwin, in the Voyage of the Beagle, there are several of great interest, not merely on account of their novelty as newly discovered species, of which there are nearly thirty, or as forming the types of genera not previously known, or of any remarkable peculiarity of form, structure, or habit, although in all these respects many of them are highly interesting; but more particularly as serving to establish or confirm several points connected with their geographical distribution.
From the structure of most of these animals and their consequent habits of life, circumscribed as they are for the most part in their locomotive powers, it might reasonably be predicated that they would, upon the whole, exhibit as distinct examples of restriction, with regard to their geographical boundaries, as any class of vertebrated animals; and that the intervention of seas and of mountains would be sufficient to limit the range of a species. Such is in fact usually the case; and not only is the same species not found in the Old and New Continents, but, with very few exceptions, not even on the opposite sides of the South American Continent, in which range Mr. Darwin s discoveries have principally been made. The occurrence, however, of Bufo Chilensis at Rio Janeiro and at Buenos Ayres on the eastern, and at Valparaiso and the Archipelago of Chonos on the western side of the continent, shows an extent of distribution exceedingly unusual if not absolutely unparalleled in this family. It is, however, still possible that further and more extended researches into the characters of the animals in question, and an examination of individuals from each locality at various ages, may prove that there are two species, which have been confounded with each other, and the anomaly may thus be removed.
But although the circumscribed range of a species may be accounted for by the reasons above mentioned, and others of a restrictive nature, it is not so easy to refer to any known or obvious cause the remarkable fact of a whole genus, consisting of numerous species, being thus geographically limited. Yet this is a well-known and very common circumstance with regard to several groups of animals. In our present researches there exists a remarkable example of this fact in the genus Proctotretus , consisting, as is now known, of at least fourteen species, all inhabiting the western coast of South America. These facts, interesting as they are, have never been sufficiently investigated, although, it must be confessed, there are so many anomalies in relation to this subject, that we must despair of ever reducing the facts in question to any thing like fixed laws.
The close approximation of the Raniform and Hyliform groups of the Anourous Amphibia is strikingly illustrated by several new forms obtained by Mr. Darwin, which are so perfectly osculant between the two families, that it is difficult to assign them a decided location. And the addition of some bufonine forms in the family Ranid , as at present constituted, and on the other hand of some amongst the Bufonid , which are no less raniform in their general structure and habits, render it increasingly probable that the single character of the presence or absence of superior maxillary teeth, must be considered as insufficient to constitute alone a natural distinctive family character. There are several minor points bearing upon the natural arrangement of the Anourous Amphibians, which are illustrated by the characters of some of the species now first described, which will doubtless at some future time assist in the construction of a classification of these animals, bearing at least a nearer approximation to their natural arrangement than any that has hitherto been promulgated.
The Ophidians have been placed in the hands of Mons. Bibron, who is at the present time engaged in completing his admirable history of Reptiles, by the publication of those volumes which are devoted to this order; and it must be considered a fortunate circumstance that the delay which has taken place in the appearance of that portion of his labours, has thus afforded the opportunity of embodying in so perfect a work, the numerous discoveries of Mr. Darwin in this particular department of Erpetology.
