chites beds of Ussuri Bay in Siberia; it is therfore referred 

 with certainty to the Brahmanic stage of the Scythic series. 

 It may be correlated with the Ceratite marls and the lower 

 part of the Ceratite sandstone of the Salt Range of India. 



Mr. R. S. Spence has recently collected some Lower 

 Triassic ammonites at a newly discovered locality one mile 

 west of Paris, in southeastern Idaho. These were sent by 

 the United States Geological Survey to the writer for iden- 

 tification, and proved to be Meekoceras, Ophiceras, Pseudo- 

 sageceras, Celtites, and several species of a new genus of 

 the Sibiritidas. 



The Lower Trias of California. In 1896 Dr. C. D. 

 Walcott discovered some ammonite-bearing limestones in 

 Inyo County, California, on the east side of Owen's Valley, 

 ten miles east-northeast of Lone Pine, three miles south- 

 east of the Reward Mill, and about fifteen hundred feet up 

 above the mill, on the Union Wash trail from Independence 

 over the Inyo Range into Saline Valley. The fossils were 

 submitted by Dr. Walcott to the writer for identification, and 

 referred to the Lower Trias, on the basis of the occurrence 

 of several genera characteristic of the Brahmanic stage of 

 the Scythic series in the Oriental region. In a preHminary 

 report (33) the writer did not venture to describe new species 

 or genera, but noted the occurrence of Namiites, Clypites f, 

 Koninckites, Meekoceras, Kingites, Gyronitesf, Xenas-pis., 

 Diyiarites, and a new genus of Tropitidae. Later collec- 

 tions and better material have confirmed most of these iden- 

 tifications, but the form referred to Clypitesh.2LS proved to be 

 a new genus of the same group ; the supposed Kingites is 

 very uncertain; the Dinarites has turned out to be a Para- 

 lecanites; and the supposed new genus of the Tropitidae 

 belongs to the Hungaritidee. 



Later collections, by Mr. H. W. Turner of the United 

 States Geological Survey, and by the writer, have added 

 greatly to the list of genera and species, bringing out even 

 more strongly the relations of this fauna to the Brahmanic 

 faunas of the Asiatic regions.
