A listing of repertory films in today's Weekend section, which is printed in advance, incorrectly reports what IMAX films are being shown at the National Museum of Natural History and when. "Galapagos" is shown daily at 10:15 a.m., 1 p.m., 2 p.m. and 4:40 p.m. "Mysteries of Egypt" is shown daily at 11:10 a.m., noon, 2:50 p.m. and 3:40 p.m.

There were several errors in the Voters Guides published yesterday in the Fairfax Weekly and the Loudoun Extra:

* A story on the Fairfax School Board race should have said that candidate Rita S. Thompson is running with the endorsement of the Republican Party.

* Mark H. Emery, a candidate for the Fairfax School Board, proposes to increase students' class time by paying regular teachers to work more hours--not by using more instructional assistants, as was reported.

* Thomas M. "Tom" Bolvin, a candidate for Virginia's 43rd House District, is not in favor of tuition vouchers for children to attend private schools.

* In the Loudoun Extra, Eugene A. Delgaudio, the only Sterling District candidate for the Loudoun County Board of Supervisors, should not have been identified as an incumbent.

The Classika Theatre production of "Aladdin and the Princess Budur," which runs weekends through Nov. 21 in Shirlington, is recommended for children. A calendar item in yesterday's Virginia Weekly sections said otherwise.

The Foggy Dogg Jog to benefit homeless animals is scheduled for tomorrow in Northwest Washington, with registration at 8:30 a.m. An item yesterday in the District Weekly's Animal Watch column gave an incorrect date for the event.

An item in yesterday's Fairfax Weekly incorrectly identified Fairfax Supervisor Robert B. Dix Jr. (R-Hunter Mill) as chairman of the county's Board of Supervisors.

An article yesterday incorrectly reported details of the Maryland State Board of Education's plan to help failing students. The story should have said that eighth-graders who fail math or reading would be required to go to summer school.

An item in Saturday's Politics column incorrectly reported the membership of the National Organization for Women. The group has 500,000 members.

CLARIFICATION

A Montgomery Weekly article about Takoma Park's elections misstated the status of a referendum on banning handguns. The referendum was taken off the ballot by a judge who ruled that it conflicted with state law. The judge's decision came after the Weekly went to press.
