• So written in first description. A typographical error, probably. Dr. Lea after- 

 wards changed the name to ohlatus. 



'^Dr. Lea credits this to Ravenel's letter, bnt neither he nor Ravenel ever described 

 it so far as I know. 



^ Ravenel here credits this species to Lea. Lea's specimens, received from Ravenel, 

 are marked Sautee Canal and South Carolina. They are rather thin and delicate, 

 of a peculiar texture, and have a shining brownish green epidermis.
