144 Notes on the Geology oj Murray Bay* 



StropTiomena alteniata, Trinucleus concentricus. 



Leptaena sericea, Asaphus platyc&pTialus, 



Ambonychia radiata. Bronteus lunatus, 



Modiolopsis nasuta. Calymene BlumenhacMi. 



Cyrtodonta, n. s. Encrinurus. 



Dalmanites. 



III. Hard arenaceous limestone and calcareous sandstone. 

 This forms the greater part of the cliff at White Point, immedi- 

 ately within the pier, and the lower part of the high cliff at L'Ecor- 

 che. It is less distinctly seen east of Cape Hen. The sand in 

 these beds is beautifully rounded as if by long attrition on the 

 shore, and occasionally there are pebbles giving some beds the 

 character of conglomerate. The following fossils were found, but 

 the hardness of the beds rendered it impossible to procure perfect 

 specimens. 



Stenopora fibrosa. 

 Columnaria alveolata. 

 Petraia. 

 Glyptocrinus. 

 Vanuxemia Montr ealensis. 

 Pleurotomaria staminea. 



P 



Orthoceras Bigshyi. 



recticameratwrn. 



Illaenus glohosus. 



IV. Thin bedded and somewhat nodular dark gray limestone. 

 Best seen at L'Ecorche ; also east of Cape Heu, and in the cliff 

 inside the pier, at the base near the west side. This bed 

 abounds in Leperditia, apparently L. amygdalina and another 

 species. It also contains Strophomena alternata, Modiolopsis 

 nasuta, and a Pleurotomaria. 



V. Hard gray quartzose sandstone with calcareous cement and 

 bands of coarse sandy limestone. At L'Ecorche, also east of Cape 

 Heu, in the cliff inside the pier, and at Little Mai Bay on the 

 beach. The fossils are 



Tetradium fihratum. 

 Lingula eva. iV. s, 

 Phynconella. 

 Pleurotomaria. 

 Murchisonia.
