muscular system, quite sufficient to prove the distinctness of the present 
species from P. satyrus with which a comparison was made, even if 
the external characters had been lacking. The skulls of the two forms 
are different externally and internally; the face of that of P. catvus 
being more prognathous, and the outline in profile more concave, the 
interorbital region directed slightly backward; the cribriform plate 
has a crista galli; the petrous bone has a sharp edge making deeper 
the pits for the occipital lobes of the brain. The hinder part of the 
vomer is covered by the pterygoids; and the nasal bone in “Sally” 
skull was ridged in the middle line, but this may be an individual 
peculiarity, as two other skulls of this species did not possess it. Other 
differences exist, but sufficient have been mentioned to show that there 
exist quite enough to separate P. catvus from P. satyrus. A 
female of this species lived for over eight years in the Menagerie of 
the London Zoological Society in Regent’s Park. The then Superin- 
tendent, the late Mr. A. D. Bartlett has given an interesting account 
of it in the Proceedings, (1. c.). She was quite young when received 
and Mr. Bartlett states that ‘Sally’ as she was called “had always 
shown a disposition to live upon animal food,” being in this respect 
quite different from other species of Simia. “Soon after her arrival, 
I found she would kill and eat small birds seizing them by the neck, 
she would bite off the head and eat the bird—skin, feathers and all; 
for some months she killed and ate a small pigeon every night. After 
a time we supplied her with cooked mutton and beef tea; upon this 
food she has done well. I have never found any ordinary Chimpanzee 
that would eat any kind of flesh. 
“Another singular habit was the producing pellets or ‘quids,’ 
resembling the castings thrown up by Raptorial birds. They are 
composed of feathers and other indigestible substances, that had 
been taken with her food. Moreover she is an expert rat-catcher, 
and has caught and killed many rats that had entered her cage 
during the night. Her intelligence is far above that of the ordinary 
Chimpanzee. With but little trouble she can be taught to do many 
things that require the exercise of considerable thought and under- 
standing; she recognizes those who have made her acquaintance, and 
pays marked attention to men of color, by uttering a cry of bon, bun, 
bun. She is never tired of romping and playing, and is generally in 
a good temper.” 
Professor Romanes in the same publication, (1. c.) narrates 
some interesting experiments he made with this animal, exhibiting her 
high intelligence. “This,” he says, “is conspicuously displayed by the
