    Description / Table of Contents: Zusammenfassung Das “symmetrische Höhenindexsystem” (sli) zur Zahlendarstellung vereinfacht die Überwachung der Rechengenauigkeit und vermeidet overflow—oder underflow—Probleme. In dieser Arbeit werden die praktischen Vorzüge des Systems am Beispiel des Graeffeverfahrens vorgeführt.
    Notes: Abstract The symmetric level-index,sli, system for representing numbers eases the monitoring of precision while avoiding the problems associated with overflow and underflow. In this paper the practical benefits of the system are displayed, using the root-squaring method of Graeffe as a vehicle.

    A new rotifer from a coastal lake in Southeastern Brazil: Hexarthra longicornicula n. sp. (1987)

    Notes: Abstract A new rotifer is described from among samples taken from coastal lakes in southeastern Brazil. Comparisons to related rotifers are made. This new animal belongs to the Hexarthra mira-intermedia species group by way of its general morphological configuration, the number of teeth in the trophi (5), and the two club-shaped caudal appendages (CSCA's). An extremely long dorsal antenna and very long setae extending from the bend in the ventro-lateral arm characterize this animal's speciation.
