358 Mr. Home's Description of the Anatomy 
of this species, as I am informed by Captain Bligh, are so 
short, that the points only are seen projecting beyond the hair. 
The Ornithorhynchus Hystrix is a nearer approach to the 
more perfect quadruped than the paradoxus ; and, as its tongue 
is similar in some respects to those of the Manis and Myrmeco- 
phaga, it was natural to look among the different species of 
these genera, for other points of resemblance. 
I have examined a figure of the Manis of Sumatra, drawn by 
the late Mr. Bell, while resident there, whose abilities as an 
anatomist and draughtsman, make his death a considerable loss 
to science.* The form of the head, the opening of the mouth, 
and the general appearance of the animal, led me to believe it a 
still further remove from the Ornithorhynchus than the Myr- 
mecophaga; and the following circumstances, in the internal 
structure of these two genera, confirm this opinion. The Myr- 
mecophaga has two caeca, which resemble that of the Ornitho- 
rhynchus ; whereas the Manis has no appearance whatever of 
caecum. 
There are two specimens of Manis preserved in spirit, in the 
Hunterian Museum, one male, the other female ; both of these 
I have examined. 
The tongue was small, cylindrical, and very long ; and the 
muscle by which it is retracted lay between the abdominal 
muscles and peritonaeum of the right side, forming a semicircle 
between the lower end of the sternum and the. navel : the theca 
in which it was inclosed, had an attachment to the lower end of 
the sternum. The tongue was smooth; and there was no ap- 
pearance of teeth on it, or on the palate. 
* This drawing is in the possession of Mr. Marsden, who proposes publishing It 
in the next edition of his History of Sumatra.
