circumstance more properly than from the extraor- 

 dinary thread-like process of the tail, I have applied 

 to it the title of chordatus. It is a native of the 

 West-Indian seas, and was taken between Cuba and 

 Martinieo, near a small cluster of little islands about 

 nine leagues from shore, where it was observed 

 , swimming near the surface. The whole length of 

 this uncommon animal, from the head to the extre- 

 mity of the caudal process, is about thirty-two 

 inches, of which the process itself measures twenty- 

 two. The plate represents it in its natural size.
