Page 356. Gymnothorax Bloch & Schneider, is properly a synonym of 

 Mureena. The oldest tenable name for the subgenus, called in tlie text 

 ^^ Gymnothorax,''^ seems to be Sldera* Kaup. 



Page 358 (899). The type of the genus Opliiclitliyfi Ahl is, according

 Genus 170 must therefore stand as Murcenopsis Le Sueur, and 170 (6) as 

 Ophichtliys Ahl.
