    C. primigenius, and not of E. antiqum, with the ridge formula of the second milk-molar of which last-named species they agree. They differ from E. antiquus in the absence of the mesial expansion of the plates, by their being wider (laterally), and in closer proximity to each other.] 39. —The left horizontal ramus of the lower jaw. It contains the third milk-molar in situ, which shows nine plates, all much worn. The discs of wear exhibit indications of crimp- ing in the middle of the plates. Three outer mentary foramina and one inner are visible. Length of fragment 8 in. Height 2-8 in. 40. —A much mutilated fragment of the left ramus of the lower jaw of a young individual. It contains in the alveolus the five posterior plates of the last milk-molar in germ. 41. — The anterior portion of both rami of the mandible contain- ing the ultimate milk-molars on either side tn situ. The left ramus is broken posteriorly to the molar. The anterior portion of the alveolus of the first true molar is present. The right ramus is broken a little behind the coronoid process of the ascending ramus. The beak is broken, otherwise the symphysis and the diastemal ridges are entire. Mentary foramina, one inner and two outer, in each ramus. Each molar has eleven plates, all much worn; the molars are inclosed in the cement, which is well preserved. Length of left ramus 11 in. Greatest thickness 2*5 in. Height 4-3 in. Length of molar 3-9 in. Greatest width 2-1 in. 42. —The right ramus of a lower jaw; the ascending ramus is imperfect, wanting the condyle and the coronoid apophysis. Part of the alveolus of the ultimate milk-molar is present, and the first true molar is in place. It contains thirteen plates and a subordinate anterior ridge and a heel. The ten anterior ridges are more or less worn. The beak is broken and the diastema are imperfect. Mentary foramina, two. Length of fragment 14 in. Length of molar 6 in. Width at second ridge 2 in. 43. —A fine specimen of a lower jaw; it comprises the horizontal rami which are nearly entire, and considerable portions of the ascending rami, and has the first true molar on either side in place. The condyles and the left coronoid apophysis
