Vertebrata With The Exception Of Mammalia PDF Download

Excerpt from A Manual of Land and Fresh Water Vertebrate Animals of the United States (Exclusive of Birds) The region covered by' this work is the whole of the United States between the Canadian and Mexican borders, neither Alaska nor the West Indian or Hawaiian Islands being included; the southern portion of Canada, however, is included, as it belongs to the same geographical region as the northern portion of the United States. With certain exceptions, all the species, as well as the geographic subspecies, of the four Classes of vertebrates above mentioned which are found in this large region, are described, the exceptions being those species which are of doubtful validity, those which are very rare, and certain Mexican species, chiefly of reptiles, which have been observed but a few times north of the boundary. Great care has been taken to state precisely the geographic limits of these species and subspecies. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
