This is an appeal from a judgment of the District Court for the Southern Dis*3trict of New York (Shirley Wohl Kram, Judge), dismissing a petition to quash two summonses issued by the Internal Revenue Service. The summonses were served upon Lehman Brothers Kuhn Loeb Inc. (“Lehman Trading”) in connection with an audit of the tax liability of its corporate parent, Lehman Brothers Kuhn Loeb Holding Co. (“Lehman Holding”). The petition to quash is filed on behalf of 24 directors and customers of Lehman Trading. The District Court dismissed the petition for lack of subject matter jurisdiction, construing 26 U.S.C. § 7609 (a)(4)(A) literally to mean, as it says, that the provisions of section 7609(a)(1), providing for notice and an opportunity to challenge a summons issued to a third-party record-keeper, are inapplicable to a summons served “on the person with respect to whose liability the summons is issued” and that an investigation into the tax liability of Lehman Holding is an investigation into the tax liability of Lehman Trading since Lehman Holding filed a consolidated return, 26 C.F.R. § l-1502-6(a) (1966).

We affirm on the well-reasoned decision of the District Court. 582 F.Supp. 257.
