278 MR. R. B. NEWTON ON FOSSILS FROM [Aug. I904, 



Post-Pliocene. 



Marine mollusca found in the region of the Dardanelles have 

 been identified with existing Mediterranean species. Hence, the 

 deposits containing them may be recognized as of post-Pliocene 

 age, and probably of contemporaneous origin with those found in 

 Cyprus (as known to us through the researches of Prof. Gaudry), 

 and in the Hellespont by Calvert & Neumayr. 



( A ) List of marine shells from the coast-cliffs west of Gallipoli 



40 to 100 feet above sea-level. 



Gastropoda. Lamellibranciiia. 



Murex Brandaris, Linnaeus. Ostrea edulis, Linnaeus. 



Murex trunculus, Linnaeus. Cerastoderma edule (Linnaeus). 



Cerithium vulgatum. Bruguiere. Pullastra pullastra. 



Gibbula adriatica (Philippi). Petricola lithopJiaga (Retzius). 



Gibbula cf. Biasoletti (Philippi). Lorvpes lacteus (Poli). 



Osilinus turbinatus (Born). Tapes Calverti, sp. nov. ( = Tapes cf. 



Diana, Locard). 



(B) A marine shell from Gallipoli Ovassi, about one mile north-east 



of Gallipoli, in a loamy clay-bed 20 feet above the sea. 



Ostrea Cyrnusii, Payraudeau. 1 



(C) List of marine shells from the other side of the Dardanelles 



opposite Gallipoli, about 1 mile inland from Tchardak. The 

 beds containing this fauna are of a sandy character, and nearly 

 50 feet above sea-level. The exact section measures about 

 10 feet in thickness, and is capped by a loamy soil full of 

 recent terrestrial shells. 



Gastropoda. 



Tritia reticulata (Linnaeus). 

 Gihbida adriatica (Philippi). 



Lambllibranchia. 



Ostrea edulis, Linnaeus. 

 Ghlamys opercularis (Linnaeus). 

 Chlamys varia (Linnaeus). 

 Cerastoderma edule (Linnaeus). 

 Mytilus edulis, Linnaeus. 

 Gastrana jragilix (Linnaeus). 

 Loripes lacteus (Poli). 

 Tapes Calverti, sp. nov. ( = Tapes 

 cf. Diana, Locard). 



The specimens of Tapes cf. Diaiice, which occur both at Tchardak 

 and Gallipoli, agree with Calvert & Neumayr's shells from the 

 Quaternary deposits of the Hellespont which are similarly identified. 2 



1 Ostrea Cyrnusii was originally 'described by Payraudeau ('Catalogue des 

 Annelides & des Mollusques de File de Corse ' 1826, p. 79, pi. iii, figs. 1 & 2) 

 as living oif Corsica, It is narrowly-elongate in form, and furnished witJi an 

 extensive ligamental area. The more modern figure, published by Reeve in 

 his 'Conchologia Iconica ' vol. xviii (1873) pi. xvii, fig. 37, of the lower valve 

 of this shell agrees in every way with the specimen collected by Col. English. 

 It may be mentioned that this species is generally united to O. lamellosa, as 

 one of its synonyms.
