A murrey taken in the Gulf of Mexico by Assistant-Surgeon 

 Rayner, of the Royal Navy, and presented to the Museum at Has-

 form and dentition ; but the spots on the body are much more 

 numerous, and the fins, instead of being distinctly banded, have a 

 continuous black edge, with a white stripe beneath it. The white 

 stripe approaches the edge of the fin at intervals, so as to give it 

 somewhat of a banded appearance when folded. Length, 1 5 in.
