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 is 

 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, i)eneath 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 oiM. nevilli, 

 and have the last two whorls increasing much more rapidly in 

 breadth, in this more resembling M. Brot's pi. 22, figure 8B ; 

 the last whorl is, however, never convexly swollen as in M. 

 nicobarica.
