fMiinm philonia is uncommon in the Karitan 

 formation, and I have found it only near tlie 

 top. It is abundant in tlic ovorlyinjl Maijothy 

 formation from New Jei-sey to Maryhmd. In 

 the southern Coastal Plahi it occurs in the 

 Middendorf arkose member of the Black 

 Creek formation of South Carolina and ranges 

 from the base of the Tuscaloosa formation 

 upward into the Eutaw formation in the 

 Alabama area. It was identified by Ward 

 from the Cheyenne sandstone of Chatman 

 Creek, Kans., but his material, which I have 

 studied, is not this species but represents 

 leaflets of Sapindopsis. 



A single complete and characteristic l(>af 

 and several fragments are contained in the 

 collections from Arthurs Bluff, Tex.

This species, the type localitj^ of whicli is 

 simply '■■ Dakota sandstone of Kansas (Lacoe 

 collection)," is at best of doubtful validity. 

 It was described by Lesquereux as follows; 



Leaf membraneous, lanceolate, jrradually tajjering to 

 the apex, narrowed to the l)ase, not dccurri'iit, soinewliat 

 curved to one side, entire, irregularly undulate; median 

 nerve thick; secondaries oblique, curved, parallel, hut of 

 unequal thickness and distance, caraptodrome. The 

 leaf is n centimeters long, 2.5 centimeters broad below 

 the middle, slightly inequilateral by the partial contrac- 

 tion of the l)orders on one side, and is not gradually nar- 

 rowed to the petiole but somewhat rounded in narrowing 

 to it. Its precise relation is not satisfactorily ascertained. 



The Texas material is fragmentary and of 

 doubtful identity.

This species, which is of doubtful validity, 

 was described from material collected in the 

 Raritan formation of New Jersey, and I have 

 found it only in the upper part of that forma- 

 tion. In the absence of venation characters 



in both the type and later collected material 

 its identification is always more or less uncer- 

 tain; and it may represent a variety of Imuhis 

 plittonia Ileer or some of the forms that have 

 been referred to Miirica loiifja Ileer, although 

 in general it is wider than the latter and more 

 elongated and less symmetrical than the for- 

 mer. A single specimen is present in the collec- 

 tion from Arthurs Bluff, Tex.
