A technique for obtaining bryozoan chromosome spreads is described. Karyotypes were prepared for the following phylactolaemate species: Plumatella emarginata, 2n = 14; Hyalinella punctata, 2n = 14; Fredericella sultana, 2n = 14; and Pectinatella magnifica, 2n = 18. Approximate numbers were obtained for Lophopodella carteri, 2n 18–22, and three ctenostomes, Pottsiella erecta, 2n = 22 or 24; Amathia semiconvoluta, 2n about 30; and Paludicella articulata, 2n about 20. Differences between the bryozoan karyotypes seen in this study correlate with taxonomy.
