269 It is remarked that the empirically consistent 'calculable' quark mass matrices recently proposed by us have a family of quark mass matrices leading to the same CKM phenomenology and predict I VUbl/Vcb"'(1/2)Jlmd/msl "'(1/2) Vus. In previous papers,l),2) considering the discrepancies between the Fritzsch type 3 ) quark mass matrices-the only survived quark mass matrices until recently-and the recent CKM phenomenology as a serious one, we have searched for and presented new types of
