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.

This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.

This is a pre-1923 historical reproduction that was curated for quality. Quality assurance was conducted on each of these books in an attempt to remove books with imperfections introduced by the digitization process. Though we have made best efforts - the books may have occasional errors that do not impede the reading experience. We believe this work is culturally important and have elected to bring the book back into print as part of our continuing commitment to the preservation of printed works worldwide.

Excerpt from A Guide to the Study of Insects, and a Treatise on Those Injurious and Beneficial to Crops: For the Use of Colleges, Farm-Schools, and AgriculturistsThe typical Crustacean cannot be said to have a true head, in distinction from a thorax bearing the organs 'of locomotion, but rather a group of rings, to which are appended the organs of sensation and locomotion. Hence we find the appendages of this region gradually changing from antennae and jaws to foot-jaws, or limbs capable of eating and also of locomotion; they shade into each other as seen in Fig. 9. Sometimes the jaws become remarkably like claws or the legs resemble jaws at the base, but towards their tips become claw-like; gill-like bodies are sometimes attached to the foot-jaws,'and thus', as stated by Professor J. D. Dana in the introduction to his great work on the Crustacea of the United States Exploring Expedi tion, the typical Crustaceans do not have a distinct head,' but rather a head-thorax (cephalothorax).About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.

Alpheus Spring Packard, LL. D. (1839-1905) was an American entomologist and palaeontologist. He was the son of Alpheus Spring Packard (1798-1884) and the brother of William Alfred Packard. He was born in Brunswick, Maine and was Professor of Zoology and Geology at Brown University in Providence, Rhode Island from 1878 until his death. He was a vocal proponent of the Neo-Lamarckian theory of evolution. His chief work was the classification and anatomy of arthropod animals, and contributions to economic entomology, zoögeography, and the phylogeny and metamorphoses of insects. He wrote school textbooks, such as Zoölogy for High Schools and Colleges (1904). His Monograph of the Bombycine Moths of North America was published in three parts (1895, 1905, 1915). Other works by him include: Guide to the Study of Insects (1869), The Mammoth Cave and its Inhabitants (1872) with F. W. Putnam, Life-History of Animals (1876), A Naturalist on the Labrador Coast (1891) and Lamarck, the Founder of Evolution: His Life and Work (1901).

Skeleton cartilaginous; 5-7 pairs of gill-openings Elasmobranchii. Sharks, Rays. 2. Skeleton cartilaginous or bony; scales often square, enamelled. Ganoidei. Sturgeon, Garpike, and Lung fishes. 3. Skeleton bony, of numerous separate bones; 4 pairs of gills...Teleostei. Cod, Cunner, Perch, etc. The sharks, though fish-like, are very different from ordinary bony fish. Their cartilaginous skeleton, includin the larger, upper lobe. They also have from five to seven gill-openings or slits, whereas the cod or perch has but one. The skin is either smooth, or with minute scales, forming shagreen. Both jaws arc armed with numerous sharp, flattened teeth, arranged in rows and pointing backward, enabling them to seize and retain their prey. Fio. 152.--Cestracion, or Australian Shark. ing the skull, is so soft that it can be cut with a knife, while the tail is one-sided, the vertebral column ending With the appearance of sharks the world of life realized a new order of things. Never before had animals lived so well adapted for the destruction of the lower orders of animals, however well protected they were by solid shells and other means of protection. Sharks and i53.-Teeth of the ces-skates are engines of destruction, tracion. being the terror of the seas. Their entire structure is such as to enable them to seize, crush, tear, swallow, and rapidly digest large fishes, shell-fish, starfish, sea-urchins, or other marine animals. Moreover their own forms are ...
