Analyses were made of subfossil Eubosmina remains from two Berlin Lakes. The first postglacial eubosminid was B. (E.) longispina. In Tegeler See it occurred from the Alleröd to Atlantic 2. In Lake Unterhavel it disappeared earlier in the Boreal. Bosmina (E.) longicornis occurred in early Atlantic 1 resp. at the end of Atlantic 2 (Tegeler See). Bosmina (E.) c. coregoni appeared in Lake Unterhavel at the end of the Boreal, in Lake Tegeler See at early Boreal. Bosmina (E.) c. thersites occurred only in sediments of Lake Unterhavel beginning in Atlantic 2. No sign of a “morphological transition” between taxa found by H OFMANN could be found in the two investigated lakes. The succession of Eubosmina taxa seems to be mainly the result of immigration.
