Meek, F. B. A report on the Invertebrate Cretaceous and Tertiary Fossils of the 

 Upper Missouri Country. <Rep. U. S. Geol. & Geogr. Surv. of the Terr. 4°. 

 vol. ix, pp. i-xiv, 1-629, pla. i-xlv. Washington, 1876. 



This great work contains descriptions and illustrations of nearly 300 species; more than 200 

 genera and subgenera are fully diagnosed, besides which full diagnoses of the families which 

 embrace them are given; also philo.sophical discussion of many important questions. The 

 greater part of the species embraced in this volume were previously, from time to time, de- 

 scribed and published, mainly in the publications of the Acad. Nat. Sc. Phila.
