Esnal, M. Daponte] Summary: A new contribution to the characterization of the salps Ihlea racovitzai and I. magalhanica, particularly their reproductive features, is presented. In both species two oocytes develop in the aggregate form, in the solitary form stolon growth is continuous. Buds grow continuously from the zone of deployment to the distal region without forming blocks or intermediate pieces. In Ihlea racovitzai the exit of the stolon and the resulting release of buds occurs later than in I. magalhanica. In the latter it takes place at the beginning of the strobilation of the stolon, which means an earlier and perhaps more continuous release of buds. The opening for the release of the buds is ventral and anterior to the nucleus in I. magalhanica and ventrolateral and posterior to the nucleus in I. racovitzai. Differences in the pattern of body muscle VII and the atrial retractors in the solitary forms are underlined. Springer-Verlag, 1990 Esnal G.
