4052. The skeleton of a Racoon (Procyon Lotor). 



The vertebral formula corresponds with that in the preceding specimen ; but, all the caudal 

 vertebrae being here preserved, they are 1 8 in number. A few of the anterior ones have hsem- 

 apophyses. The fabella is preserved behind the condyle of each femur. 



Mus. South. 



The following, to No. 4056 inclusive, are parts of the same skeleton of a Racoon (Procyon 

 Lotor) : 



Hunterian. 



4053. The skull. 



The entocarotid pierces the inner border of the tympanic bulla : there are no ectocarotid 

 canals. The mastoid is thicker than the paroccipital. 



4054. The articulated bones of the trunk and pelvic arch. 



The vertebras are : 7 cervical, 14 dorsal, 6 lumbar, 3 sacral : the caudal series is not com- 

 plete. Nine pairs of ribs articulate directly with the sternum. The costal parts of the trans- 

 verse processes of the seventh cervical vertebra not being present, those processes are not per- 

 forated by the vertebral arteries. The spinous processes of the trunk-vertebrae converge to 

 the twelfth dorsal vertebra, as the centre of motion in the back. Metapophyses begin to be 

 developed as tuberosities upon the diapophysis of the anterior dorsal vertebrae, increase, and 

 pass upon the zygapophyses in the twelfth dorsal, and are so continued to the end of the 

 lumbar series. The anapophysis separates from the metapophysis on the eleventh dorsal ver- 

 tebra, increases in length to the third lumbar, and decreases in the other three. The diapo- 

 physes subside in the last three dorsal vertebrae. 



4055. The articulated bones of the left anterior extremity. 



The supra- and infra-spinal fossae are of equal depth. The internal condyle of the humerus 

 is perforated : the scaphoid and lunar bones have coalesced.
