creature. Otherwise the external characters (see fig. 1, p. 47) are 

 much as in Manatus latirosiris. 



At the time of the death of the animal various circumstances 

 prevented me from at once making a detailed examination of the 

 viscera. Thej 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. latirostris, 

 for which I am indebted to Mr. Gerrard, jun. If I had had only 

 the descriptions and drawings of Dr. Murie and Prof. Garrocl 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 Mi-. 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 am 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.
