bed and lower portion of the marl they are unquestionably to be 

 referred to the Navesink, or to the Navesink-Hornerstown marl. 



In marl pits along the creek a mile or more above the village 

 the upper portion of the Navesink-Hornerstown bed is exposed 

 and above it the Vincentown limesand. These localities may 

 have yielded some of the material credited to Mullica Hill. The 

 Kirkwood sand is now exposed in a small bank in the southern 

 limits of the village and overlies the Vincentown sand at the 

 marl pits, and while the writer has never noted any fossils in it, 

 the possibility of some Miocene forms being found in this 

 locality must not be wholly overlooked. 



Alloway and Riddleton. — A number of specimens are credited 

 to "Allowaystown." No greensand marl beds are known nearer 

 to Alloway than two and one-half miles northwest along the 

 headwaters of Swede's Run. Here there are old pits in the 

 Manasquan marl. Since these exposures are only a mile west 

 of Riddleton, the material credited to that place may have come 

 from them, but there is less certainty regarding that credited to 

 Alloway. In the vicinity of the latter place there are numerous 

 exposures of a dark, tough clay, sometimes called the Alloway 

 clay, 1 known to be of Miocene age and now included in the 

 Kirkwood formation. Possibly the material "from Alloways- 

 town" may be Miocene and from this clay. 



Shiloh, Jerico, Stozv Creek. — Miocene fossils have been 

 found in great abundance in the marl pits along the headwaters 

 of Stow Creek near Shiloh and Jerico in Cumberland County. 

 These beds have often been called the Shiloh marl and the speci- 

 mens credited to Shiloh, Jerico and Stow Creek all came without 

 question from these pits. These pits lie four and one-half to five 

 miles southeast of Alloway and perhaps the material labeled 

 Allowaystown is also from them. The Shiloh marl is regarded 

 as a part of the Kirkwood formation. 



Greensand No. 5, of New Jersey. — Many of the specimens are 

 referred by Cope to "Greensand No. 5, of New Jersey," "Green- 

 sand No. 4, of N. J.," etc. From the localities cited it has been 

 possible to identify "No. 5" as the Hornerstown marl, but I
