These selected paragraphs distill the contents and give you a quick look inside The Appendages, Anatomy, and Relationships of Trilobites: Look inside the book: The appendages of Neolenus, Isotelus, Ptychoparia, Kootenia, Ceraurus, Calymene, and Acidaspis are discussed, as fully as circumstances warrant, in the first part, and new restorations of the ventral surfaces of Neolenus, Isotelus, Triarthrus, Ceraurus and Cryptolithus are included It is not supposed that these restorations will be of permanent value in all of their detail, but they are put forward as the best approximations to the real structure that the writer is able to present from the materials so far discovered. ...The most striking characteristics of the appendages are as follows: the antennules are long, and turn backward instead of forward; none of the limbs projects beyond the margin of the dorsal test; the exopodites extend beyond the endopodites, reaching very nearly to the margin of the test; the endopodites are not stretched out at right angles to the axis, but the first three segments have a forward and outward direction as in Triarthrus, while the last four turn back abruptly so that they are parallel to the axis; the limbs at the anterior end of the thorax are much more powerful than the others; the dactylopodites of the endopodites show a fringe of setæ instead of three spines as in Triarthrus and Neolenus.
