Locality P3854. South bank of small valley, southwest corner of SE. j sec. 15, T. 36 N., 

 R. 65 W. (See plate 2, fig. 1.) A fair coUection of leaves was obtained from a lens of dark-gray, 

 hard, calcareous siltstone, estimated to lie about 1000 feet above the base of the Lance f ormation :

 Laurophyllum coloradensis 



Locality P3855. North bank of small valley, near center of SW. l sec. 13, T. 36 N., R. 65 W. 



The following species were obtained from a bed of dull-gray, thinly bedded siltstone, estimated to 



be about 1200 feet above the base of the Lance: 



Anona? robusta Magnoliophyllum cordatum 



Carpites walcotti Phyllites sp. 



Carpites sp. Platanophyllum montanum 



Cissus? lobato-crenata Quercus? viburnifolia

Laurophyllum coloradensis Vitis stantoni 



Locality P3856. Head of small valley, southeastern part of SW. l sec. 2, T. 36 N., R. 65 W. 

 Only a few species were obtained, from a massive, buff to light-gray, soft claystone, estimated to 

 lie about 1600 feet above the base of the Lance. As nearly as can be determined, this is the same 

 locality as U. S. Geological Survey Locality 1462, referred to as "a clay bed . . . one and a half 

 miles southwest" of the U-L Ranch.' Only the following species were obtained: 



Equisetum sp. Trapa? microphylla 



Filicites knowltoni Typha sp. 



Localiiy P3857. Middle of steep cliff along east bank of Lance Creek, center of SE. \ sec. 

 25, T. 37 N., R. 65 W. (See plate 2, fig. 2.) Numerous plant remains occur in an irregular stra- 

 tum of dull-gray siltstone in direct association with numerous well-preserved but fragile shells of 

 fresh-water invertebrates. This is the locality (U. S. Geological Survey Locality 1464) about 

 which Stanton and Knowlton remarked, "one of the best localities is in a bluff on the right bank 

 of the Lance Creek just below the U-L Ranch." " I obtained the following species from this 

 horizon, estimated to be about 1700 feet above the base of the Lance: 



Apeibopsis? discolor Grewiopsis saportana 



Cyperacites sp. Laurophyllum salicifolium 



Dombeyopsis trivialis Magnoliophyllum cordatum 



Dryophyllum subfalcatum Platanophyllum montanum 



Fraxinus leii Quercus? viburnifolia
