Discussion. 



Major R. Gr. Edwards Leckie said that the localities from which 

 he made his collection of fossils were at Garrasgooi and at various 

 points along the Golis Range, west of that mountain. The Golis 

 Range had an elevation of 5000 feet above sea-level, and formed the 

 northern edge of the great inland plateau of Somaliland. All this 

 plateau was covered by a bed of fossiliferous limestone, averaging, 

 so far as he could judge, about 250 feet in thickness. In the 

 Guban, or Maritime Plain, between the plateau and the coast, 

 the limestones which occurred at the Eilo Range and Bihendola 

 were, in the opinion of those who had examined the fossils, of 

 Jurassic age. He had not observed Tertiary limestones in the 

 Maritime Plain. 



k%The Author thanked Major Leckie for his remarks, and [the 

 Fellows present for their reception of his paper.
