The cranial extremities of the bones show well defined articular surfaces, the depressions and eleva- tions in which are homologous in the bones of the left and the right hand sides. (See P^ig. 2.) A layer of fibro- cartilage probably was interposed between the styloids and the os tcinporis. The description of the styloid liones given by ^^'arren, which applies well to the specimen before the writer, is as follows : p,j. 2 Articular sur.

This process is rarely seen in ])lace ; but in the head of a young elephant we find it connected with the tem- poral bone by a ligament. The cranial extremity of this bone, pre- senting the marks of the attachment of a fibro-cartilage, which inter- vened between it and the os temporis, is more than an inch across its longest diameter. From this end the bone tapers with some degree of regularity to its cervical extremity, which is pointed. The bone is cur\ed at its upper part; and one side of the curved portion is fluted like the human clavicle, where the subclavian muscle lies under it. The texture of the bone is c^uite dense; for which reason it has been preserved in a state of perfect integrity, notwithstanding the slenderness in its ; The Basi-hyal Bone (Figs. 3,4, 5).—The extreme length of the bone, measured at the symphyses with the thyro- hyals, is cm.
