Like Philippi's M.flammulata [Java], but with very promi- 

 nent longitudinal ribs and distinct regular spiral striation, the 

 latter a character which at once separates it from the preceding 

 variety ; coloration bright and distinct.

I am by no means sure that these specimens really belong 

 to the same species as the two preceding varieties, though evi- 

 dently all these forms are united by M. Brot. The throughout 

 prominent, slightly nodulose spiral keels are highly characteris- 

 tic of this form, which is smaller than Reeve's above-quoted 

 figure and more decollate. Anfr. 4 to 6 ; long. 35, diam. 12-^-
