Like Philippi’s M. fammulata [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.

Iam 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. 122
