by dissection, the Sooty Monkey, at least, is destitute of laryngeal 

 sacs, (but has large cheek pouches) and we may readily infer the 

 same of the other species, its immediate ally. The relationship, as 

 it appears to us, between these two animals and the Indian Macaci, 

 is that of representation. They have not indeed the muzzle so pro- 

 duced and the supra- orbital ridge so developed as in the Macaci; 

 but in these points they exceed the African Guenons generally, and 

 are also we think stouter in their proportions. They appear, indeed, 

 to constitute a form, intermediate between the Macaci and Cercopi- 

 theci, on the one hand ; as are the Colobi between the Semnopitheci 

 and Cercopitheci on the other. What the Colobi of Africa are to 

 the Semnopitheci^ these two monkeys (and others have perhaps to 

 be added) are to the Macaci, With respect to the genus Cercocebus, 

 I should be inclined to restrict it, excluding from it the Grivet and 

 Green Monkeys, and modify its characters accordingly, taking the 

 Sooty and White-eyelid Monkeys as its typical examples, a plan 

 which, it appears to me, is preferable to the creation of a new ge- 

 neric title, which often leads to confusion." 



Mr. Owen exhibited a preparation of the ligamentum teres in the 

 Coypou, which he had received from Mr. Otley of Exeter. 



TWEEDSIDE PHYSICAL AND ANTIQUARIAN SOCIETY. 



A stated Quarterly meeting of this Society, the establishment of 

 which we mentioned in vol. i. p. 159, was held at Kelso on Monday 

 last, Major Watson, Woodside, in the Chair. The donations re- 

 ported as received since last meeting, and those announced as now 

 on their way from various contributors, were of a description equally 

 interesting and valuable with any that have been noticed at the pre- 

 vious meetings of the Society. 



From Mr. Herman, London. — Magnificent tiger skin. The ani- 

 mal, when alive, must have measured fully 11 feet from tip to tip. 



From Mr. Wilkie of Ladythorn. — Three fine specimens of foreign 

 shells (Pearl Nautilus and Leopard Cowries). 



It was announced to the meeting that Mr. Selby of Twizel, one 

 of the most distinguished of our native naturalists, had signified his 

 intention of presenting to the Society the appropriate and valuable 

 donation of a collection of Scottish insects. 



Specimens of native birds have been received from the Rev. Joseph 

 Train; Mr. Gilbert Bruce; Mr. John S. M'Dougal, Coldstream; 

 Mr. Johnston, Todrig, &c. Of these we may mention the follow- 

 ing :—
