A group of about thirty-five Cuban men and women attended the 11:45 A. M. Mass at St. Patrick's Cathedral yesterday in "memory of all victims massacred in Cuba under the Batista regime."

The women identified themselves as members of the Catholic Ladies of Cuba, with headquarters here.  The men said they belonged to the 26th of July Movement, which derives its name from the first open revolt against the government of President Fulgencio Batista on July 26, 1953.

Spokesman for the Roman Catholic Archdiocese said that the Cubans had not been expected at St. Patrick's and that their presence at the Mass was of their own accord.

Armando Abascal, who identified himself as propaganda director of the 26th of July Movement, attempted to hand out leaflets after the Mass, but was prevented form doing so by the police.
