Arabian deposits, especially large "Naticoid shells, a small Gryphcea, 

 and Spatangoid echinoderms. A collection of Tertiary fossils from 

 Eas Ghissa (Arabia) was made a few years ago by Lieut.-Col. 

 Dr. A. S. G. Jayakar, and presented to the British Museum, 

 containing yellowish limestone -casts of Naticoid shells and a Cam- 

 panile resembling those from Somaliland, while the matrix of 

 these specimens exhibited foraminiferal organisms, particularly an 

 abundance of Operculina and Amphistegina. 



But, as well as this correlation of the Somaliland Tertiary 

 limestones with those of Arabia and India, somewhat similar 

 palseontological resemblances may be traced in the" Eocene rocks 

 of Egypt and other countries of Northern Africa (Nigeria, 1 the 

 Cameroons, 2 etc.), through Southern Europe to the Paris Basin, 

 and so on to the Bracklesham Beds of England. 



II. Literature. 



A brief review of the various papers on the entire palaeontology 

 of Somaliland will now be given in chronological order. 



The earliest record of fossils from Somaliland was made by 

 II. J. Carter 3 in 1857, who determined the following specimens, 

 but without descriptions or illustrations, obtained by Capt. (after- 

 wards Sir Eichard) Burton from the neighbourhood of Berbera, and 

 correlated them with the Jurassic fauna of Cutch in India : — 



Belemnites canaliculatus, Schlotheim. 

 Terebratula intermedia, J. Sowerby. 

 Terebratida microrhynclia, J. de 0. Sowerby. 



Area (sp. ?). 



Exogyra auricularia, Goldfuss. 



A number of specimens from Ouarsangueli ( = Warsangeli) were 

 described and partly figured by Dr. A. T. de Eochebrune 4 as of 

 Neocomian age, the horizonal fossil being Ostrea Conloni, Defrance. 

 New names were given to the other species, the whole series com- 

 prising three gastropods, seventeen lamellibranchs, one echinoid, and 

 one coral. 



Miss C. A. Eaisin, 5 in a petrographical paper, referred to some 

 limestones containing foraminifera (Amphistegina, Ghbigerina, etc.), 

 polyzoa, etc., which she considered might be late Cretaceous or
