* Schlegel says that this species belongs to the division " a orifice branchial 

 recul6 en arriere et vers le bas ;" but by tlie figure quoted, and by tlie close afS- 

 nity of this species with the following, I am induced to believe tliat the gill- 

 cavity opens su[>eriorly. and not laterally.
