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. calvus 

 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. calvus 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 Simla. "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
