From this list it appears that Point of Rocks has a flora of 55 species, 

 of which number 28 have not been found elsewhere. Of the remaining 

 27 forms 14 are open to question, leaving only 13 having an unquestioned 

 distribution in other horizons, and of these latter at least two {Haly- 

 menites major and Sequoia reichenbachi) have a distribution ranging 

 through nearly the whole of the Cretaceous. The number of outside 

 species is therefore reduced to 11, which is really very small when we 

 take into consideration the size of the flora and its supposed affinities 

 with the true Laramie. 



On page 150 we have given a list of the plants found at Coalville, Utah, 

 some 1,800 feet below the top of the marine Cretaceous. It embraces 13 

 forms, of which 5 are either doubtful or not specifically determined. Of 

 the 8 remaining, 4 are also found at Point of Rocks, and two species addi- 

 tional (Salix elongata and S. Integra) are not entitled to much consideration 

 from the fact that they are not easily identified in any formation. 



From the localities in the vicinity of Harper station, on the Laramie 

 plains, the following species have been detected :
