﻿160 ME. R. B. NEWTON ON THE [Feb. I905, 



A new form of Heliopora collected by Mrs. Lort-Phillips from 

 the Uradu Limestone near the Rugga Pass, was described and 

 figured by Prof. Gregory 1 . as Heliopora somaliensis, and regarded as 

 of Turonian age. 



In 1901, Herr Oscar Neumann 2 announced the discovery of 

 Jurassic and early Cretaceous fossils at various localities in Galla- 

 Land, material which is under description by Dr. Edgar Dacque, 3 

 a first fasciculus having been issued in 1904 on the ' Untere Kreide/ 

 containing figures and descriptions of mollusca — Eooogyra Couloni, 

 Defrance, Cucullcea Gabrielis, Leymerie, Fholadomya Picteti, Mayer- 

 Eymar, etc., from the Neocomian ; and Trigonia Picteti, Coquand, 

 etc., from the so-called Aptian(?). Astroeoenia subomata, d'Orb. 

 var. africana, Weissermel, is also described by Dr. Dacque from 

 Neocomian strata of this part of Africa. 



III. Desceiption of the Fossils. 

 (a) Gastropoda. 



Remarks on the Genus Campanile as found in 

 Somaliland. 



Among the specimens mentioned in Prof. Gregory's memoir of 

 1900, were some more or less silicified limestone-casts of large 

 gastropodan shells which, on account of possessing the plaited 

 columella, were identified by the present writer as Nerincea, and 

 consequently classed as Cretaceous in age. They were referred to 

 as fossils of the ' Nerincea-IAmestoiiQ ' from Dongorreh and Bur- 

 Dab, and regarded as Neocomian, under the following identifica- 

 tions — Nerincea, sp. nov., and Nerincea allied to Renauxiana, 

 d'Orb. 



The further material from Somaliland that has now been studied 

 embraces some better specimens than were formerly available, so 

 that these shells can be recognized as belonging to the family of 

 the Cerithiidse and to the genus Campanile, 4 ' the type of which is 

 Cerithium giganteum of Lamarck, a species characterizing the 

 Lutetian or Middle Eocene rocks of England, the Continent of 

 Europe, Northern Africa, Asia Minor, etc. It is to this type that 

 the different forms from Somaliland are undoubtedly related. There 

 is always considerable difficulty in dealing with casts at any time, 

 but careful comparison of them on the present occasion with many
