Locality 126* . 'The section at this locality, Long-street's marl 

 pit near Crawford's Corner, has already been given (See p. 92). 

 This fossiliferous bed in the Navesink marl is limited to about 

 2.5 feet, the fossils being sparsely represented below although 

 a larger number of species are present there than in the upper one 

 foot of the bed, which is a mass of shells of Gryphaea convexa 

 with some examples of Ostrea mesenteries, these being essentially 

 the only species present. The fauna from this locality is the 

 largest which has been collected from the Navesink marl proper, 

 although a larger number of species have been recognized from 

 the Mount Laurel facies at Atlantic Highlands. The species 

 which have been recognized at this locality are as follows :
