forms from near the same locality having been defined by 

 the author in an earlier volume. In regard to these the writer 

 remarks : " Considering all the similarities between these Laramie 

 fossils and their representatives in the Mississippi and Ohio water- 

 sheds, I venture to state that these farther western waters of the 

 Laramie times were the original home of much of the Uhio fauna 

 of these more eastern recent localities." c. s.

8. Illinois State Geological Survey. Bulletin No. 4. Year 

 Book for 1906. H. Foster Bain, Director. Pp. 260, with 4 

 plates and 4 figures. Urbana (University of Illinois), 1907. — 

 Earlier bulletins have already been noticed in the Journal (xxii, 

 543, xxiii, 227). The present one, No. 4, contains the adminis- 

 trative report of the Director for 1906, with also an account of 

 the progress made in the topographic survey being carried on 

 with the cooperation of the U. S. Geological Survey and the 

 State Geological Commission. The State has hitherto had no 

 accurate and official topographic map, so that the results of the 

 present work are most important. Of the special subjects also 

 discussed may be mentioned several chapters on the study of 

 coal and also an account of two remarkable drill cores, both from 

 Hamilton county, one 920 feet deep (at Delafield) and the other 

 (near McLeansboro) extending to a depth of 1294 feet. The 

 records kept and here summarized are very complete and yield 

 valuable geological section's. 



9. Connecticut Geological and Natural History Survey, 

 Bulletin No. 8. Bibliography of the Geology of Connecticut ; 

 by Herbert E. Gregory. Pp. 123. Hartford, 1907 (The Case, 

 Lockwood & Brainard Company). — The eighth bulletin of the 

 Connecticut Geological Survey is devoted to the bibliography of 

 the geology of the State. This has been prepared by Prof. 

 Gregory after a critical study of the literature extending over a 

 number of years. It presents a practically complete list of titles 

 of papers published up to January, 1906, with brief sta'ements 

 giving the main results brought out in each. Upwards of three 

 hundred entries are included in the bibliography, and a list of 

 nearly one hundred references to maps is also added. The work 

 cannot fail to be of great value to all concerned with Connecti- 

 cut geology.
