Summary: Twenty‐one multiple births have been studied in a series of 338 infants with major congenital malformations. The incidence of twin births in this group was about four times the normal expectation. It was not possible in this series to indicate whether monozygotic or dizygotic twinning was related to congenital malformation. Comments and data are given about the diagnosis of zygosity. It is apparent from this study that membrane diagnosis is still being used loosely in obstetrical records to indicate types of twins.
