present report, a good deal of geological and biological work has 

 been accomplished in connection with the regular topographical 

 work of the survey. Three parties were in the field, and explored 

 portions of Utah, Arizona, Colorado and New Mexico. Consider- 

 able geological work was done, while Dr. J. T. Rothrock and assist- 

 ant John Wolfe collected nearly 12,000 specimens of plants, repre- 

 senting over 1,100 species. A goodly number of animals were 

 collected, and have been distributed to specialists. The report is 

 accompanied by a number of descriptions of fossil vertebrates 

 from New Mexico by Prof. Cope.
