Most probably the specimens from Stat. 105 and 153 will not have lived at these great 

 depths, in accordance therewith they are dead shells.

The specimens are young even very young. I compared them with a fine specimen from 

 the Red Sea and found the sculpture identical. However, young shells if they are moreover 

 bleached are very difficult to be identified with complete certainty in this group. Sowerby has 

 omitted this species. Tryon thinks it is identical with M. annulata.

The specimens are young and partly bleached, the sculpture agrees with specimens from 

 the Andamans. I have consulted Mr. Melvill for these specimens, who writes: "Not quite 

 typical, but am inclined to agree with your determination".

The specimen from Stat. 164 is a fine full-grown shell, the other ones are young and 

 in that state come very near to M. anmilata Reeve. As the disposition of the spiral lirae, 

 better agrees with that of this full-grown specimen than with those of M. annulata from 

 Zanzibar in my possession, I have referred them all to M. Jiammigera.
