Jersey the stratigraphic position of the "yellow sand" was considered 

 to be above the "lime sand" or Vincentown formation of Clark, and 

 it was believed to be intimately related to that formation. But 

 Clark, from his published statements, seems to h'ave been somewhat 

 uncertain in regard to the relationships of this bed. 1 It appears that, 

 while at first he was inclined to follow Cook in including the "yellow 

 sand" in the Cretaceous, yet at a later date he arrived at a different 

 conclusion and considered the beds to be of Miocene age. 



A careful search by the writer, in company with Knapp, disclosed 

 good fossils in the "yellow sand" at several localities, and fragments 

 of fossils may be found in the formation at almost every exposure. 

 At the base of Gold Hill, one mile south of Eatontown, Terebr alula 

 harlani and Gryphaea vesicularis occur in abundance, and with them 

 fragments of spines and plates of echinoids, and broken bryozoans. 

 At California Hill, near Deal, fossils occur near the summit of the 

 formation in abundance, Terebratula harlani again being the most 

 common form, associated with several species of pelecypods. In the 

 bank of the Manasquan River, at New Bergin Mills, one and one- 

 half miles west of Farmingdale, this formation is well exposed in an 

 unweathered condition, and contains a somewhat larger percentage of 

 glauconite than in the other localities mentioned. Fossils are exceed- 

 ingly abundant at this locality, some layers of the sand being filled 

 with bryozoan remains, with some echinoids, the fauna being essen- 

 tially that of the Vincentown lime-sand. In other beds at the same 

 locality, fragments of Terebratula harlani were observed. 



I have interpreted these fossils as definite evidence that the sand 

 in which they occur is of Cretaceous age, and is to be correlated with 

 the Vincentown lime-sand. If it be thought worth while to designate 

 the "yellow-sand" fades of this formation by a separate name, it 

 may be called the "Long Branch sand," as has been suggested by 

 Knapp. 



Clark's contention that the "yellow sand" is Miocene in age is 

 based upon the supposition that the present position of the included 

 fossils is not their original position, but that they have been washed
