The specimen does have some similarities to H. jacnensis, but H. jacnensis is typically a much smaller species, rarely exceeding 25 mm.  Also, it usually has a very distinctive sculpture, strongly corded on the early whorls, but smooth on the later whorls.  And, it is more elongate in outline.  Your shell is more rounded in outline.
