6. OTuIa ; sp, Indet. 



We abstain from describing this species, because the only 

 two specimens which we have are immature. They resem- 

 ble O. variabilis, but the general form and the aperture are 

 wider, and the shells are covered with excessively minute re- 

 volving striae. Except in being striated, they resemble O. 

 inflexum Sowb. They were found on the reef.
