The Coeman's limestone contains the Gjpidiila gafeata fauna 

 and is placed as the first of the Devonian formations. It is fol- 

 lowed by the New Scotland, Stormville, Becraft, Kingston, Oris- 

 kany, Esopus and Onondaga limestone. We note that the author 

 concludes that " a careful study of the Helderberg and Oriskany 

 faunas of New Jersey has brought out conspicuously the absence 

 of any sharp dividing line between these two horizons either of a 

 stratigraphic or of a faunal nature " (p. 96). 



The Newfoundland grit, which follows in the Green Pond 

 Mountain region, contains a fauna essentially that of the Onon- 

 daga limestone, without the mixture of Oriskany species, which 

 w^as stated erroneously to be the case in the preliminary report. 

 The Monroe shales (700 to 1000 feet thick), as well as the follow- 

 ing Bellevale flags (1800 feet), contain the Tropidoleptus carinatus 

 fauna with no admixture of Chemung species. 



The Skunnemunk conglomerate alternating with red sandstone 

 follows without observed fossils and terminates the Paleozoic 

 series of the State. A considerable number of new species are 

 described. n. s. w.

In the first volumes there are combined an interesting discus- 

 sion of the changes the underground basis of the State has sup- 

 posedly undergone in past geological time which must stand on a 

 highly theoretical basis, with the thoroughly practical and eco- 

 nomic problems connected with modern roads and the brick indus- 

 try. The county reports are made as attractive and interesting as 

 scientific reports can be made by applying the skill of experts to 

 the interpretation of each section of the physical phenomena 

 examined, treating each subject so as both to bring out the new 

 scientific facts and to artistically explain them ; and, throughout, 

 the State geologist has succeeded in weaving into his reports 

 those practical qualities which are so highly appreciated by the 

 general public for whom they are primarily prepared, h. s. w.
