The hyoid bone is very complicated and singularly varied in conformation in the genera and species of tortoises, but it is not necessary for our purposes to enter into a detailed description of it. From what has preceded, it may be observed that there is more difference in the arrangement and mutual relations of the bones of the head in the different tortoises, than probably in the heads of all quadrupeds, and most assuredly than in the entire class of birds. There are proportional, though not so considerable, differences in the other parts of the skeleton. The most general character of the tortoises, as is well known, consists in their having the bones of the thorax outside, enveloping with a cuirass or double buckler what subsists of the muscles, and serving even as a shelter to the bones of the shoulder and the pelvis. This dorsal buckler is formed principally of eight pairs of ribs, united towards the middle by a longitudinal series of angular plates, which either adhere to the annular parts of so many vertebrae, or constitute a part of them. What is most remarkable is, that these annular parts alternate with the bodies of the vertebrae, and do not correspond to them directly. The ribs catch in by sutures with these plates. They also catch together through all or a portion of their length. There are eight vertebrae in front, which do not share in this arrangement. The first seven, which are the ordinary cervical, are free in their movements. The eighth, which may be considered as the first dorsal, is. . . This item ships from La Vergne,TN., RareBooksClub.com<
