GEOLOGICAL FORMATIONS. 15 Holectypus cenomanensis Guér. Holectypus planatus Roemer. Pygaster truncatus Agass. Epiaster distinctus Agass. Hemiaster similis D'Orb. Cottaldia carteri Duncan. Near Kalhát A. v. Krafft found a great development of limestones. Amongst the fossils which I have seen in his collections the following eccur from this locality : Radiolites sp. Pyrina sp. Terebratula sp. 34 These rocks apparently belong to the Upper Cretaceous. Plate IX shows these limestones at Kalhát overlain by sub-recent conglomerates. According to A. v. Krafft these Cretaceous rocks pass up into Nummulitics, which are of Laki age, and probably in places rest uncon formably on the basic serpentinous series. There is also a possibility that a limestone underlying the Nummulitic pebble bed at Darzeit is also of this age (page 89). It seems likely, therefore, considering the wide distribution of Upper Cretaceous limestones in the area, that the sea at this period extended over the whole of Southern Persia, and as far as the south eastern corner of 'Omán, washing the shores of a land composed of the Carbo-Triassic and basic igneous rocks of 'Omán. 5. Hormuz Series. Of later date than the Hippuritic limestone, are the beds here classed. They are intimately associated with the Hippuritic limestone at Khamir on the Persian coast between Bandar Abbás and Lingah, where portions of the red gypsum bed with hæmatite are found pene trating the Hippuritic limestone, as a continuation of an outcrop of the same rock occurring with lava flows. The lava flows were poured out on a Cretaceous surface, but it is not unlikely that some of them were submarine, as they are interbedded perfectly evenly with beds of sedimentary origin. At Khamir Eocene rocks are exposed as well KINY
