The Insurance Company brought this action against the Zimmermans to recover, as subrogee, the amount it had paid under a fire insurance policy issued by it to Myrtle W. and Forrest H. Hagenbuck, on account of a fire loss suffered by them, alleging the fire was caused solely by the negligent acts of the Zimmermans. The Zimmermans filed a third party complaint against Skelly Oil Company.

*619 From an order denying Skelly’s motion to dismiss the third party complaint, Skelly has sought to appeal.

Such order was clearly interlocutory and not a final order. It does not fall within any of the categories of interlocutory orders made appealable by 28 U.S.C.A. § 1292(a) and no effort was made to comply with 28 U.S.C.A. § 1292 (b), nor did the court direct the entry of a final judgment, under Rule 54(b), Fed.Rules Civ.Proc.

The appeal is dismissed without prejudice.
