county, Kansas, but most of them, whether from Kansas or Texas, were new species. 

 Three from Doctor Newlon were also new species, one of them being a new genus. 



All the species have been described by Professor Hyatt in the recently issued 

 Second Annual Report of the Geological Survey of Texas. Dr. Newlon and myself 

 have had our names given to one species each, and one species of which tha type 

 specimen was also from Kansas has been named for Professor Dumble, the director 

 of the Texas survey. The entire list is as follows: 



Temnocheilus crassus, Oswego. 



Metacoceras dubium. Junction City. 



Metacoceras Hayi, Junction City. 



Metacoceras inconspicuum, Junction City. 



Domatoceras umbilicatum, Oswego. 



Asymptoceras Newloni, Oswego. 



Phacoceras Dumbli, Junction City. 



There are other specimens described by Professor Hyatt, but as they are not 

 new we omit them. 



Doctor Newlon's specimens are from carboniferous strata. The higher beds in 

 Geary county, as I have remarked previously, I have called permo-carboniferous. 

 Recently Professor Tchernyschew, of St. Petersburg, in company with Prof. H. S. 

 Williams, of Cornell University, have made a short examination of the section ex- 

 posed at Fort Riley, and, while agreeing that the lower beds are permo-carbon- 

 iferous, they state that the upper beds — where the Phacceras is — are decidedly 

 permian, the Russian professor assuring me that both faunal and lithologic char- 

 acters can be duplicated in the permian of his own country. How this will affect 

 the classification of Professor Hyatt I do not know, but in his report he treats all 

 the specimens as carboniferous. 



Professor Hyatt's descriptions are as follows: 



Temnocheilus cbassus, n. s. 



Loc, near Oswego, Kas. 



Carboniferous. Coll. National Museum. 



Figs. 8, 4, and 5, magnified one-third. 



This species is represented only by a fragment; but the characteristics are so 

 peculiar that there is apparently little doubt of its being the representative of a 

 distinct form. 



The sides are convex and do not converge towards the umbilici so abruptly as
