SYSTEMATIC AFFINITY OF ACROPORELLA ASSURBANIPALI 113 the variability oftlie species and some qualitative characters such as the shape of thallus, laterals and reproductive organs would have required more abundant material. The thallus is apparently cylindrical and simple. Primary laterals are arranged in moderately close whorls. Their position between whorls, alternated or in continuity, is not evident. However they are phloiophorous and rather strong, almost perpendicular to the stem axis. The transverse section of the primary pores is

It is Upper Hauterivian in age, and is the first date obtained for this basal part of the formation. The Orbitolina Limestone is generally recog- nized to be Upper Barremian in age from the foraminifera [Palorbitolina lenticularls (Blumenbach) and Choffatella deciplens Schlumberger) that it contains (Beydoun, 1968: 92).
