Farkas, H.: Data to the knowledge of Eucypris sarsi and Erpetocypris obliqua (Crustacea: Ostracoda)

Figs. 1-5. Eucypris sarsi DADAY: 1. left shell, 2. right shell, 3. shell in superior view, 4. shell' in inferior view, 5. furca. — Figs. 6-7. Erpetocypris obliqua DADAY: 6. furca, 7. right shell. sarsi: "Von oben oder unten gesehen sind die Schalen eiförmig (Fig. 2c), in der Mitte am Breitesten, das Hinterende abgerundet, das Vordere spitzig." In this case it is not only the text which is faulty but the figure itself shows the shell as "spitzig", whereas it is by no means pointed either in the superior or the inferior views, but characteristically elongated in a beak-shape. This feature comes well to the fore in the figure submitted herein, although not as manifest as no the wholly closed shells. This difference is the more important as DADAY pointed out the very shape of the shells as the most important characteristic distinguishing it from all other known Eucypris species. With respect to Eucypris sarsi I should like to call attention to the fact that the shells are highly characteristic in the inferior view. In the open state, or when disattached from each other, the shell-margins display conspicuously the wide, arcuately decurrent rim, larger on the left (in the inferior view on the right) than on the right half. Incidentally, this feature —the various-sized and diversely arcuate rims —are to be regarded as probably the best differences between the Eucypris taxa. Illustrations from the inferior view in recent descriptions also seem to refer to this interpretation. I should like to add yet to the description of the species that the cilia of antenna I are long, projecting over the apex by the antennái length itself. The natatory bristles of antenna II hardly project beyond the apex of the terminal claw. The mandibula is thick, chitinized, with 5 teeth. The original description also mentions that the clearing leg is straight and only apically uncinate. The maxilla resembles that of Eucypris vir ens JURINE, and the terminal joint of the palpus is twice longer than wide. An error of a similar character can be found also in the case of Erpetocypris obliqua. DADAY writes of the furca as follows : "der Hinterrand in der ganzen Länge
