64 CARNIVORA. 



islands, belonging to the governor, which have hair similar to the 

 feathers of the silken hen. 



A Fox [(Canis Vulpes, Linn.) 1 .] 



I have compared this animal with the dog, so that what I have not 

 taken notice of, is to be found in a dog. 



The mouth and larynx as in the dog. The roof of the mouth black. 

 A worm in the tongue. No length of the oesophagus below the 

 diaphragm. No elastic ligament to the anus, as in a dog. The caecum 

 folded on itself 2 . 



The clitoris not cavernous, but of a soft glandular substance, as in 

 the dog ; the termination of which is spongy, and seems to be a con- 

 tinuation of the plexus retiformis, and terminates like the corpus 

 sesamoideum in the valves of the aorta. Hardly any erector clitoridis ; 

 and, from the nature of the clitoris, there was hardly any use for them. 

 The uterus not red, but blackish. The orifice of the meatus a little 

 prominent in the common vagina at the upper part, and there is 

 another prominence on the lower part just opposite the other 3 . 



Has three nipples on each side. 



The aorta ossified in some parts, and at these parts formed sacs ; 

 which might be the cause of the [aneurism al condition of the] aorta of 

 the hog [described in] Tyson's ' Anatomy' 1 .' 



[A Virginia Fox (Canis Vulpes, var. Viryinianus).~\ 



A pretty large worm in the tongue. A black roof of mouth. The 

 larynx as in a dog. The thyroid glands are as high as the os hyoides, 

 just on the inside of the maxillary glands, but a little further back. 

 The oesophagus does not adhere closely to the aorta, but is some distance 

 from it ; there is a membrane that passes from the anterior surface of 

 the oesophagus, its whole length, below the curve of the aorta, over its 

 left side, not adhering to it ; and is by its other edge attached to the 

 aorta, near its adhesion to the spine ; and the lower edge of this mem- 

 brane is attached to the diaphragm : the right side of the oesophagus is 

 attached to the right side of the aorta. By these means there is a 

 complete bag, having no opening into it ; which I should imagine was 

 for the motion of the oesophagus, as it is pretty loose. The same bag 

 I saw in the other. The stomach as in a dog. The duodenum stronger 

 than any of the other intestines, excepting the colon : situated as in a
