The whole specimen was originally in alcohol. It was then skinned, mounted, 

 and placed on exhil)ition. The skeleton was prepared and the viscera put in 

 alcohol. The mounted specimen has since been taken down and made into a 

 study skin which is well made ami in good condition except for a small naked 

 spot on the right hip and the loss of many toenails. It is much lighter than 

 normal, from exposure to light and probaljly from the effects of alcohol. The 

 skeleton is in excellent condition and on exiiibition in the Division of Compara- 

 tive Anatomy. The viscera, both abdominal and thoracic, are well preserved.
