Mr. Justice Harlan

delivered the opinion of the Court.

This is a companion case to No. 67, Nashville Milk Co. v. Carnation Co., decided today, ante, p. 373. In the present case the Court of Appeals has held that a private action for treble damages * does lie under § 4 of the Clayton Act for violation of § 3 of the Robinson-Patman Act. 239 F. 2d 144. Because of the conflict with the decision of the Court of Appeals for the Seventh Circuit in the Nashville Milk Co. case, 238 F. 2d 86, we granted certiorari. 352 U. S. 1023.

The complaint in this case alleges both sales “at unreasonably low prices” and price discriminations in violation of § 3 of the Robinson-Patman Act. For the reasons set *390 forth in our Nashville Milk Co. opinion, ante, p. 373, we hold that the complaint should have been dismissed insofar as it rests on alleged unlawful selling at unreasonably low prices, and that the respondent was entitled to a trial as to the charges of unlawful price discrimination. Accordingly, the judgment of the Court of Appeals is vacated, and the case is remanded to the District Court for further proceedings consistent with this opinion.

It is so ordered.

[For dissenting opinion of Mr. Justice Douglas, joined by The Chief Justice, Mr. Justice Black and Mr. Justice Brennan, see ante, p. 383.]

The complaint does not ask for injunctive relief under § 16 of the Clayton Act.
