114 Frof. J. W. Oregory — Fossil Corals from Eyyiit, etc. 



J 1789, a block with corallites 7 mm. in diam. : old beacb, Camp 7, 



"Wadi Barud. 

 J 2138, a small specimen but with well-preserved characters : lower 



raised beach, north of Qosseir. 



2. Orbicella mammillosa, Klunzinger, 1879. 

 Korallentli. roth. Meer., pt. iii, p. 49, pi. v, tig. 5 ; pi. x, fig. 10. 



Distribution. — Kecent : Eed Sea. Fossil, Pleistocene : Egypt and 

 Gulf of Tadjura (Faurot), lower raised beach, north of Qosseir, 

 No. J 2145. 



This specimen is worn and is fragmentary ; it has three cycles of 

 septa, a large columella, and some of the corallites are oval in section. 

 In a previous paper (Geol. Mag., 1898, p. 242) I included this 

 Orhicella in 0. forskali, and I still think that it may well be merged 

 in that species. But as it is necessary to contrast these fossils as 

 closely as possible with the recent Ked Sea fauna, I am, for this 

 purpose, recording the specimen under Klunzinger's name. The 

 following species is provisionally accepted for the same reason. 



3. Orbicella laxa, Klunzinger, 1879. 

 Op. cit., pt. iii, p. 49, pi. v, fig. 3; pi. x, fig. 9. 

 Distribution. — Eecent : Eed Sea. Fossil, Pleistocene : Egypt. 

 H 1633, a large block with thin walls, thickened by some secondary 



calcification : Camp 4, Wadi Hamraweiu, near Qosseir. 

 H 1633tZ, a specimen with coi'allites varying from 8 to 10 mm. in 



diam. : Camp 4, Wadi Hamrawein, near Qosseir. 

 K 1663, a specimen with somewhat smaller calices, 7 mm. in diam. 

 The corallites are close, and have very little exotheca; the 

 walls are thin, and the septa number 27 to 30. None of the 

 sux'face is shown. This is the coral which differs most from 

 the central type of 0. laxa, but I do not see any adequate 

 reason for excluding it from that species : 380 feet above 

 sea-level, near Camp 7, Wadi Shigeli. 



ECHINOPOEA, Lamarck, 1816. 

 1. EcHiNOPORA FBUTioiTLGSA (Ehrenbcrg), 1834. 



Stephanoeora hemprichii, forma fruticulosa, Ehrenberg, 1834, Beitr. Korallenth. : 



Abh. k. Akad. Wiss. Berlin fiir 1832, p. 301. 

 Echinopora fruticulosa, Klunzinger, 1879: Korallenth. rotb. Meer., pt. iii, p. 55, 



pi. vi, fig. 4. 



Distribution. — Eecent: Eed Sea. Fossil, Pleistocene: Egypt, 

 380 feet above sea-level, near Camp 7, Wadi Shigeli, K 1660. 



This specimen is the irregular nodular base of a coral with calices 

 5-5'5mm. in diametei', so they are somewhat smaller than in the recent 

 corals, and the paliform processes are perhaps less distinct. It is, 

 moreover, not raised in definite branches, but would probably have 

 developed thus had it grown larger. In other respects it appears to 

 be the same as the recent forms. 



K 1665, from the same locality, is a fragment of Echinopora, but 

 is specifically indeterminable.
