Patting aside the question whether Turbo granulahis is an 

 independent species or nierety a variety of Turbo coroncdus Gni. as 

 asserted by some, a single specimen obtained is a ciepressed- 

 tm-binate shell with about five whorls ornamented with a spiral 

 series of nodules and granules of which the sub-and supra-sutural 

 series are the most prominent. On the body-whorl there are four 

 such prominent series; the uppermost is subsutural, the next 

 is in the continuation of the suprasutural of the penultimate 

 whoi'l, the third is at the periphery and the fourth is somewhat 

 below thü peripher.y on the base, the place where the last three 

 are present being more or less angulate. Umbilicus open.

This shell already described by me frum the Lower Musashino 

 of Miyata is very numerous wherever it is found. Yet even the 

 largest specimen is not larger than that found in the above forma- 

 tion, being only about 11 millim. in height and diameter. 



Fossil occurrence. — Otake, Shisui, Tega, Shito (most nume- 

 rous). Lower Musashino of Miyata.
