24 Messrs. R. B. Newton and G. C. Crick on some 



species of Ceplialopoda, [Belemnites kuntJcotensi's) reappears 

 in the bed from the Kuntkote Sandstone below, and not a 

 single species passes from tliis bed into the higher beds — the 

 Oomia group. Waagen recognized only four European 

 species in the Katrol Sandstone, all of which belong to the 

 beds with Aspidoceras acanthicum. Hence he considered 

 the Katrol Sandstone to be of Kimeridgian age and to be the 

 equivalent of the zones of '"^Perisphincies" mutahilis and 

 Oppelia tenitilobata, a view generally adopted by subsequent 

 writers ■^. 



De Lapparentf refers the lower part of the Katrol Group 

 to the Sequanian and tiie upper part to the Kimeridgian. 



The fossiliferous deposits in the neighbourhood of the 

 villages of Al-Kura and Samma, to the north-east of Dihala, 

 are certainly of Upper Jurassic age, and are most probably 

 homotaxial with the upper part of the Katrol Group in Tjiitch 

 and with the zone of Oppelia teniiilobata, or the beds with 

 Asp>idoceras acantlncuviy in Europe. 



In his article on the " Jurassique^' in the ' Grande Encyclo- 

 pedie' (vol. xxi. 1895, ])p. 322-331) Prof. Dr. E. Haug gives 

 (p. 330) a map — after Neumayr and the more recent works of 

 ISJikitiuj Rothpletz, and Hyatt — showing the distribution of sea 

 and land during Up|)er Jurassic times. A Central Mediterra- 

 nean sea is represented extending from the northern part of 

 India on the east, over the western part of Asia, and almost 

 the whole of Europe, as far as Central America on the west. 

 From this sea a gult — termed the Ethiopian gulf — is indicated, 

 extending from the neighbourhood of Cutch and the southerij 

 part of Baluchistan in a south-westerly direction, terminating 

 at the south between Madagascar and Africa. This excludes 

 the whole of Arabia, but includes on the west Somaliland, a 

 portion of Abyssinia, and the eastern coast of Africa as far 

 south as the south of Madagascar, and on the east the north- 

 western part of Madagascar. 



The present discovery by Major Hazelgrove shows that the 

 northern part of this gulf should include also the south-west 

 part of Arabia.
