Show 48 MR. F. E. BEDDARD ON THE [Jan. 19, creature. Otherwise the external characters (see fig. 1, p. 41) are much as in Manatus latirostrls. At the time of the death of the animal various circumstances prevented m e from at once making a detailed examination of the viscera. They were accordingly placed in carbolized water and left for a day or two. It is fortunate that I was compelled to take this course, as in the other event they would have probably been thrown away before the arrival of a carcass of M. latirostrls, for which I a m indebted to Mr. Gerrard, jun. If I had had only the descriptions and drawings of Dr. Murie and Prof. Garrod to compare my dissections with, I should have come to various erroneous conclusions-not, indeed, on account of any deficiencies in those drawings and descriptions, but simply on account of the variability of certain of the organs and the immense difficulty of detecting minute divergencies between an organ in one animal and its description in another. In addition to the specimen which I obtained from Mr. Gerrard, I found among the Prosector's stores some of the viscera of a small male Manatee, which I imagine to be that which arrived in 1893 in company with the mother, and died a day or two afterwards. But I a m not positive about this, and the individual may be that which was obtained by the Society in 1889. In any case the youth of the specimen has enabled me to discriminate between real specific characters and differences probably due to age. Fig. 2.
