Summary
A study of the ultrastructure of the nuclear envelope of the salivary glands cells in the sciarid Bradysia suggests that it probably consists of four membranes, instead of two as found in most cells. The fine structure associated with the pores closely resembles that described in amphibian oocytes by Wischnitzer 1958.
