There was an unfortunate typesetting error with a translocated line on page 278. The second paragraph on this page should be corrected to read as follows:

The Polycomb locus was formerly thought to be located in the right arm of chromosome 3 (Lindsley and Grell 1968) as it maps only about 0.3 units to the left of Antennapedia, a homoeotic gene localized in 3R in or just to salivary chromosome doublet 84B1,2 (Hannah-Alava 1969; Denell 1973; Duncan and Kaufman 1975). The paracentromeric region is subject to a severe inhibition of meiotic recombination, however, and Puro and Nygren (1975) have recently demonstrated that the Polycomb locus is in the left arm within salivary gland chromosome interval 77EF–80. They also performed dosage studies with Pc² which suggest that this allele is an antimorph, that is, an allele whose product in some way antagonizes the function of the product of the normal allele (Muller 1932). The present study was initiated to localize the locus more precisely, and to extend the analysis of dosage relationships.
