Turbinolia pbaretra Lea. 



San Augustine. 



Flabellum cuneiforme var. pacbypbyllum Ampbibelia natcbitocbensis Vaugban. 

 Gabb and Horn. Madracis jobnsoni Vaugban. 



Upon examining- the above lists, from the association of Oculina and 

 the large Madracis with the other species, the conclusion is reached that 

 the beds in which the corals occur were laid down in water probably less 

 than .50 fathoms in depth. 



Shark River beds, New Jersey. TllC SpeClOS frOm thcSC bcds arC : 



Flabellum mortoui A'augbau. Balanophyllia inauris Vaugban. 



Trochocyatbus conoides (Gabb and Horn). Endopacbys sp. 



The corals indicate a depth of 100 fathoms or more. The presence of 

 large amounts of glauconite would indicate a depth of between 100 and 200 

 fathoms. 



CLAIBORNE SANDS BED. 



The species that occur in this bed are: 



(?) Flabellum cuneiforme Lonsdale. Platytrocbus claibornensis de Gregorio. 



Spbeuotrocbus nanus (Lea). Turbinolia pbaretra Lea. 



Spbenotrocbus claibornensis Vaugban. Turbinolia claibornensis Vaugban. 



Platytrocbus stokesi (Lea). Rbectopsammia claibornensis Vaugban. 



Platytrocbus goldfussi (Lea). Endopacbys maclurii (Lea). 



The basis for forming an opinion regarding tlie depth at which these 

 beds were laid down is not very good. There is an absence of strictly 

 rhallow-water forms, but we know that all of the genera that are recent, as 

 well as fossil, also occur in moderately shallow water. As no reef building
