“The total length of the skeleton, without cartilage, is 14 feet 8 inches; the head measures 2 feet 5½ inches in length, and the lower jaw 2 feet 3 inches in length. The first three cervical vertebræ are anchylosed; the next one is more or less free; and the remaining three are anchylosed again. The dorsals are ten in number, the last bearing a short rib 8 inches in length. Five of these ribs are jointed direct to the sternum; the following two meet the cartilage of the fifth rib. “The sternum is composed of four pieces, 20 inches long, with a width of between 5 and 7 inches. It is not yet sufficiently cleaned to enable me to have it photographed; this, however, will be done as soon as possible, and copies forwarded to the Society. The lumbars number twenty, the last nine having V-bones attached. The fifth lumbar is 17½ inches high, 4 inches wide at the top, and 11¾ inches at the base, including the side processes. The eleventh lumbar is the widest, being 4¾ inches at the top. The caudals probably amounted to 13; but five of these are missing; the basal one is very small, about the size of a pea; and as it was firmly attached to the second last, there can be no mistake about it. “The head is 2 feet 5½ inches long and 14 inches across at the widest part; the lower jaw 2 feet 3 inches long and 6¼ inches high behind the tooth. The left tooth measures 6 inches in length, 3⅜ inches in width, and is 1¾ inch thick [not well represented in the figure]. The space between the teeth measures 7¼ inches. The limbs are very imperfect; all the smaller bones are missing; and there is only a part of one scapula. I did not find the pelvic bones. “This animal was captured about a year ago, near Lord Howe’s Island.”—_Krefft_, P. Z. S. 1870, p. 426. THE END.
