4069. Some of the bones of the skull of a young Coati-mondi (Nasud). 



The deciduous canines, and the four deciduous molar teeth, are retained. The two parietal 

 bones show the development of the bony tentorium upon their posterior margin. In the 

 right upper maxillary bone the first true molar is just appearing behind the last deciduous 

 molar, and the germs of the fourth, third and second premolars are displayed above the teeth 

 which they would have displaced. In the right ramus of the lower jaw, the germs of the third 

 and fourth premolars and that of the permanent canine are exposed. 



The animal from which these bones were derived was called by Mr. Hunter the " Swash." 



Hunterian. 



The following, to No. 4079 inclusive, are parts of the same skeleton of the Coati-mondi 

 (Nasua).

They are naturally articulated together, with the distal epiphyses of the radius and ulna. 

 The scaphoid and lunare form one bone. There is a supplementary ossicle wedged between 

 this bone and the metacarpal of the pollex, external to the trapezium.
