Brot (1. c. p. 324) says that he is unable to distinguish M. crenifera Lea (Brot 1. c. 

 fig. 9), from M.mamensis\ in accordance therewith he may have named specimens from the 

 same island. The specimens now under consideration, agree fairly well with those I had formerly 

 sent to that authority for comparison, v. Martens (Siiss- u. Brackw. Moll. p. 305) makes only 

 mention of M. ci'enifera, as inhabiting Java.

The largest specimens are still a trifle larger than those (75 Mill.) recorded by Brot ; 

 one of them has the polished surface on one side, mentioned by v. Martens (1. c. p. 192), the 

 black incrustation is wanting on the whole length, and on more than a third of the length, the 

 epidermis has not only disappeared, but also part of the shelly matter has been ground away 

 and becomes more or less transparent on that side.
