464 ME. A. STEAHAN ON A PHOSPHATIC CHALK [Aug. 1 896, 



Ten yards west of the above. 



Massive chalk with flints, some paramoudra. ft. ins. 



Flaky chalk with few flints 4 



passing down into 



Phosphatic chalk, poor in phosphatic grains 1 



Phosphatic chalk, richer 1 4 



Hard creamy nodular limestone, as above. 



Ten yards east of the first Section. 



Flaky chalk with flints, a very few phosphatic grains at the 

 base. A small, nearly spherical flint, 2 inches from the 



base, contained some grains 



Hard nodular limestone, as above 1 



Hard white chalk, piped with phosphatic chalk, as above. ... 3 



The hard nodular limestone referred to in the above sections not 

 only resembles the Chalk Hock, but occurs at the horizon assigned to 

 that stratum on stratigraphical evidence. The fossils collected by 

 Rhodes confirm this view. Specimens from the Upper Chalk worked 

 in the northern part of the pit included, according to the identifi- 

 cation of Mr. Sharman, the following forms : — 



Ventriculites decurrens. 

 Serpula ilium. 

 Cidaris-spine. 



„ clavigera-s-pme. 

 Bourgueticrinus. 

 Echinocorys vulgaris. 

 Micr aster cor-bovis. 



„ cor-testudinarium. 



Salenia. 



Crisina. 

 Entalophora. 

 Ehynckonella Mantelliana. 



Terehratula semiglobosa. 

 Terebratulina gracilis. 

 „ striata. 



Inoceramus Cuvieri? 

 Lima spinosa. 



The beds assigned to the Chalk Eock contained : — 



Cidaris- s pines. 



Holaster planus, Mant. (about 



4 feet above the phosphatic 



band). 



Terebratula semiglobosa. 

 Terebratulina gracilis. 



In the phosphatic band fish-remains abounded, both minute- 

 pellets and teeth. Among the latter Mr. E. T. JSTewton, F.E.S., 

 identified : — 



Corax falcatus. \ Oxyrhina (a tooth about 



Odontaspis. '< f inch long). 



An exposure of the Middle Chalk a few yards south of the out- 

 crop of the Chalk Eock yielded : — 



Ventriculites. \ Spondylus striatus. 



Lima spinosa. \ Fish-remains. 



Ostrea Normaniana. 



While the lowest beds seen in the pit contained : — 



Ehynchonella Cuvieri. \ Inoceramus mytiloides* 



Terebratula semiglobosa. \
