A close ally of M. nicobarica, constantly, however, distin. 
guished by the almost cylindrical instead of more or less convex 
whorls, the upper ones not abruptly attenuate, and the last one 
not tumidly swollen; the sculpture is very similar, but the 
markedly more strongly incised spiral striation at the base 
whorls appears to be characteristic. 
var. andamanica, nov. [vel M. andamanica, n. sp. ?]. 
Possibly a distinct species, though at present, I believe, it ig 
correctly classed as a local variety of M. nevilli. It is at once 
distinguished by the upper three or four whorls being invari- 
ably longitudinally ribbed, the ribs being not at all prominent 
and slightly but distinctly arcuate; quite young specimens 
show this ribbing throughout, the ribs only becoming obsolete 
on the lower portion of the last whorl. Generally but slightly 
decollate, eight whorls remaining; covered with a rust-brown 
coating, beneath which the shell is light green, irregularly and 
very slightly spotted with brown below the suture; throughout 
spirally striated; a single specimen only has this spiral sculpture 
obsolete on the central portion of the last two to three whorls. 
Themajority of specimens are smallerthan type figure of M. nevilli, 
and have the last two whorls increasing much more rapidly in 
breadth, in this more resembling M. Brot’s pl. 22, figure 8B; 
the last whorl is, however, never convexly swollen as in M, 
nicobarica.
