Belongs to a group of which M. hevculea, Gould, may be cited 

 as an example, but is much larger, lias never such regular folds as 

 that species, nor are its concentric striae so prominent as to form 

 nodulous ridges as in M. herculea ; it is probably one of the most 

 ponderous species of the genus ; the revolving striae are more 

 prominent near the sutures, and at the base of the shell they are 

 also much crowded and more elevated.

Differing chiefly from the typical form in the absence of spiral 

 striation and basal contraction of the aperture.

Smaller and more compact than the above, with the spiral striae 

 at the base of the last whorl very distinct but more crowded than 

 in typical M. gloriosa.

•' Closely resembles the preceding in shape of the whorls and 

 spiral striation at base of the last whorl; relatively even more 

 solid ; appears to be perfectly smooth throughout, m ith the 

 exception of the above-mentioned basal striation." (A'cvill.)
