﻿Vol. 6 1.] TERTIAEY FOSSILS OF SOMALILAND. 159 



Tertiary — possibly Miocene age. This material was obtained by 

 Cant. King at Mount Eilo, south of Zeila (lat. 10° 30' N., and 

 long. 43° 35' E.). 



A series of Neocomian fossils were described and figured by 

 Prof. C. Mayer-Eymar 1 during 1893, which had beeu collected by 

 Prof. Keller on the south-western slopes of the Somali plateau, 

 along the valley of the Faf, a tributary of the Webi Shebeli. It 

 consisted of cephalopods, gastropods, lamellibranchs, and echinoids, 

 which in the aggregate were referred to four already-known species 

 and eleven new forms. 



During the year 1896, Prof. J. W. Gregory 2 published a list of 

 Jurassic fossils from Bihin collected by Mrs. Lort-Phillips, which 

 were determined by Messrs. G. C. Crick, 3 E. Bullen Newton, 4 and 

 P. A. Bather as Belemnites subhastatus, Zieten, Parallelodon Eger- 

 tonianus, Stoliczka, Bhynchonella Edwardsi, Chapuis & Dewalque, 

 and Bh. subtetrahedra, Davidson. In the same paper Prof. Gregory 

 described a new species of coral, under the name of Oryptocoenia 

 Lort-Phillipsii, found in the Duba Limestone, which he doubtfully 

 referred to the Neocomian age. 



Prof. Gregory 5 noted the value of a single specimen of Bhyncho- 

 nella subtetraJiedra, determined by Dr. P. A. Bather, which was 

 found by Dr. Donaldson Smith in Somaliland, as indicating the 

 presence of Jurassic rocks in that region. 



Pour forms of Perisphinctes collected by Dr. Donaldson Smith 

 from the rocks of Tug Turfa, were described by Mr. G. C. Crick 6 

 and regarded as characteristic of an Upper Jurassic horizon. 



Prof. Gregory's 7 most comprehensive paper on the Somaliland 

 fossils was published in 1900. It contained descriptions of the 

 corals and echinoids found in the raised-reef and plateau-lime- 

 stones of that country, together with certain molluscan determina- 

 tions made by the present writer, as well as forms of foraminifera 

 identified by Messrs. C. D. Sherborn & P. Chapman, and some 

 brachiopods determined by Dr. P. A. Bather. The horizons recog- 

 nized were post-Pliocene, Eocene (?), Turonian (or Cenomanian?), 

 Neocomian, and Jurassic.
