PER CURIAM:
This is an attempted appeal from administrative denial of a Social Security disability claim on grounds of res judicata. The Secretary also refused to reopen earlier claims. Such refusals to reopen and determinations that a claim is res judicata are not reviewable. Matos v. Secretary of H.E.W., 581 F.2d 282 (1st Cir. 1978). The court below correctly dismissed for want of jurisdiction. AFFIRMED.
