. Bulletin of the British Museum (Natural History), Geology. AND FAUNAS OF THE TAURUS MOUNTAINS 423 outcrop the Seydisehir Shales are succeeded stratigraphically by a group of well- bedded, often massive, jointed, grey and pink detrital limestones, here termed the Sobova Limestone. Most of the beds are unfossihferous, but many contain un- recognizable crinoid or cystoid ossicles, some contain large concentrations of small brachiopods (Eodalmanella sp.), and a few yield what has proved to be the most prolific Ordovician trilobite fauna in the district. With the exception of a single enrolled individual of Symphysurus, all the trilobites are represented by isolated fragments, mostly cranidia and pygidia. The strata are available for collecting at only one place on the hill-side, shown on the map as locality (see Fig. 6). The fauna will be described in detail at a later date, but the provisional list of determin- ations includes the following :â-Agerina sp. nov., Apatokephalns sp., Carolinites sp., Geragnostus sp., Illaenus sp., Neseuretus ? sp. indet., Niobe sp., Ampyx sp. and TARA5QI SECTION SOBOVA SECTION Tnia ssic Lsc .

The precise dating of this assemblage must await its detailed description, but there is nothing to suggest that it is later than Arenig Series, that is to say not significantly younger than the Seydisehir Shales, so that the junction of the two groups of strata, though not exposed here, is probably conformable, as in the section north of Tarasgi (Fig. 7)..
