Geology and Mineralogy. 79 



Among the latter are Arietites indicating the inferior Lias and 

 Stephanoveras indicating a middle Jurassic horizon. 



The Cretaceous system is indicated by a rich fauna including 

 species of lower, middle and upper Cretaceous age. This fauna 

 includes 3 species of Rhizopoda, 38 Anthozoa, 16 Echinoidea, 2 

 Vermes, 95 Lamellibranchiata, 54 Gastropoda, 24 Cephalopoda, 

 1 Thoracostraca, 8 Pisces, 1 Reptile, a total of 242 species. 



The Tertiary system is recognized by 67 species of ? Eocene 

 and Miocene age, including 3 Echinodermata, 53 Lamellibranchi- 

 ata and 11 Gastropoda. 



Hippotherium peninsulatum Cope and Protohippus Costilloi 

 Cope, are from the Upper Miocene, and from the Pliocene and 

 Quaternary are the following genera of vertebrates ; Spheroma ?, 

 Glyptodon, Sceledoterium , Rhinoceros ? ', Equus, 5 species, Plati- 

 gonus, 2 species, Palauchenia, Auchenia, 2 species, Holomeniscus, 

 Eschatius, Bison, Aphelops, Mastodon, (1 Trilophodon, 2 Tetra- 

 lophodOn species), Elephas, 2 species. w. 



3. Geological Survey of New Jersey. (Ann. Rept. 1892. 

 367 pp. 8vo and two folded maps.) — This report includes Pt. I, 

 Surface Geology by Rollin D. Salisbury ; Pt. II, Preliminary 

 Report on the Cretaceous and Tertiary, W. B. Clark, with a 

 geological map of portions of Monmouth and Middlesex Counties, 

 scale 1 mile to the inch. Lists of the invertebrate fossils are given 

 for the Lower Marl, Middle Marl, Upper Marl, and Shark River 

 Marl beds, and Heilprin's list of the Neocene fossils. A chapter 

 is devoted to discussing the origin of Greensand, and three plates 

 of colored illustrations of the mode of formation of Glauconite 

 grains are reproduced from the Challenger Report on Deep Sea 

 Deposits. Part III, is on the Water supply and Water power by 

 C. C. Vermeule and is accompanied by a map of the state. Part 



IV, Artesian wells of southern New Jersey by Lewis Woolman. 



V. Notes on Sea Dikes of the Netherlands and Reclamation of 

 the Lowlands of the Netherlands by the state geologist. w. 



4. Elementary Paleontology for, geological students; by 

 Henry Woods, B.A., F.G.S. pp. 222, smalLSvo, 1893. (Cam- 

 bridge University Press, London). — This little hand-book places 

 before the British geologist a concise account of the chief charac- 

 ters of the hard parts of invertebrates, sufficient for the recogni- 

 tion and the classification of fossils into their proper class, order and 

 sub-order, and for some of the more important genera brief diag- 

 noses of their characters are given and the geological range of each. 

 Except that the subdivision of the geological systems are in terms 

 of British geology, the book will be a useful one to the Ameri- 

 can geologist who is chiefly interested in identifying the age of 

 rocks by their fossils. 



5. Geology of Boston Basin ; by Wm. O. Crosby. Vol. i, Part 

 I, Nantasket and Cohasset, 177 pp., 8vo. (Occasional Papers 

 Boston Society of Natural History, IV). — This is a contribution 

 to the detailed structural geology of Eastern Massachusetts illus- 

 trated by maps and numerous figures and sections. A chapter is 

 included on the microscopic examination of the newer eruptive 

 Rocks of Nantasket by Geo. P. Merrill. w.
