ness. It is overlain by eighteen inches of sandy oolite, which is 

 capped by a compact bed of oolitic limestone, everywhere bored by 

 small vertical tubes of Marine Annelida. This rock has yielded 

 most of the Gasteropoda which I have collected from the oolite-marl ; 

 the fossils are so entirely imbedded in the matrix, that they have to 

 be carved out of the rock. The direct evidence of the existence of 

 Anthozoa in considerable numbers, added to the abundance of the 

 spiral univalved Gasteropoda (Nerinrm) which nestle in coral-forma- 

 tions, together with the indirect evidence of a superabundance of 

 Brachiopoda, added to the lithological character of the marl itself, 

 which appears to be the product of coral-mud and other reef debris, 

 leads to the conclusion that the Oolite-marl is a portion of a Jurassic 

 coral-bank.
