THE MAGOTHY. 33 



to the Magothy and the Raritan, even when including- under 

 the head of Raritan all the Island species, some of which may 

 in reality be Magothy and not Raritan at all. The flora "con- 

 tains a number of modern types not found in the Raritan, and 

 has a general facies allying it to those floras elsewhere which 

 are usually classed as Cenomanian such as that from the Dakota 

 sandstone of the West or that from the Atane beds of Western 

 Greenland. Comparing this flora with that of the world we 

 note that it contains 42 species of the Albanian or Gault and 

 49 species of the Cenomanian or Senonian, and that while it 

 marks the upper limit of 13 Albian or Gault species, it marks 

 the lower limit of 17 Cenomanian or Senonian species." 



The faunas of the Cliffwood clays have an especial interest 

 from the fact that they represent the earliest abundant marine 

 invertebrate fauna known in the Cretaceous of New Jersey. 

 This fauna occurs at several localities which will be mentioned 

 in order. 



Locality 105. At Cliffwood Point this fauna occurs in smooth, 

 concretionary nodules, for the most part not in situ, which may 

 be gathered along the beach in great numbers at low tide. A 

 few of the nodules were found imbedded in the clay near the 

 water level. Probably all of them have been weathered out of 

 a very few feet of strata, the nodule-bearing bed being some feet 

 below the plant-bearing beds of the same locality. The most 

 notable feature of these fossiliferous nodules is the great num- 

 ber of crustacean remains which they contain, indeed, nearly 

 every one of the concretions, when broken, yields remains, more 

 or less fragmentary and crushed, of one of these creatures, and 

 a crab of some sort seems to have been the nucleus around which 

 nearly every one of these concretionary nodules in the clay has 

 been formed. Notwithstanding their abundance, no attempt has 

 been made in the present report to give descriptions of the various 

 forms, except in one single case of a species which also occurs 

 commonly in the Woodbury clay. In addition to the crustaceans 

 these nodules have yielded a goodly number of mollusca, and the 

 following species have been recognized 1 : 



1 Additional investigation has led to some changes in identification and 

 nomenclature from the preliminary lists previously published.
