yellowish-gray color, and althougli its stratification is regular, it seems 

 to liave undergone some degree of metamorphism. 



From Provo Valley oiu^ journey was by the wagon -road to Salt Lake 

 City. At the museum in the city Mr. Barfoot sliowed me some fossils 

 that had been collected at different places in the Territory, among which 

 I recognized some of the species, specimens of which were brought from 

 Upper Kanab, Southern Utah, by Professor Powell, whence these also 

 are reported to have come. After renewing my outfit at Salt Lake City 

 I tm^ned eastward, going by way of Parley's Park, to Coalville, on Weber 

 Eiver, where a large series of fossiliferous Cretaceous strata is exiDOsed. 



In the An. Eep. U. S. Geol. Sur. Terr, for 1872, p. 439, Mr. Meek gives, 

 as the result of his investigations in Weber Valley, a detailed section of 

 the strata exposed there, from the vicinity of Coalville to Echo Canon. 

 This section was found to represent, with suf&cient accuracy, the Creta- 

 ceous strata of that vicinity, except that there seems to be in it, near the 

 southeastern end, some du])lication of strata, doubtless caused by the 

 presence of a fault there. This, however, does not seriously impair the 

 usefulness of the section. About 3,000 feet in thickness of these strata 

 'are fossiliferous, many of them profusely so. The following list com- 

 prises only those that have been found within the compass of this section, 

 in the neighborhood of Coalville. 



The greater part of the species of the following list were published by 

 the late Mr. Meek in the Am. Eep. U. S. Geol. Sur. Terr, for 1872, and 

 vol. iv U. S. Geol. Sur. 40th Parallel. Other publications of a part of 

 them were made by myself in vol. iv U. S. Sur. & Expl. West of lOOth 

 Meridian, Powell's Eeport on (tcoI. Uinta Mts., and in another part of 

 the present volume.
