rom the probably equivalent bed in Shishijima Island, off the west coast of Kyushu. They are mostly G. cf. fountaini YOUNG and partly indetermined. The specimens are described in detail, with a suggestion that subspecific separation may be possible between Kyushu and Texas. Also the relationship between Graysonites and the so-called Submantelliceras is discussed. Notes are given on the stratigraphy around the Graysonites-bearing beds, with a discussion of correlation. The Goshonoura group is Cenomanian in the main part and probably ranges down to Upper Albian in the lower part. Whether it ranges up to Turonian or not is questionable.
