■ The classification of the formations from the top of the Kiger to the Wellington 

 shales, inclusive, is lhat of Dr. Cragin, except that he termed Kiger and Salt fork divisions 

 of theCimarron series {Col. Coll. Sludies, Vol. VI, March 27, 1896. pp. 3. 1&-40). The 

 following year Dr. Cragin revised the classification of the Cimarron series, changing the 

 limits and names of some of the formations and drawing the line of separation between the 

 Salt Fork and Kiger divisions at the lop ol the Dog Creek formation instead of at its base, 

 as in the former classification (Am. Geol., Vol. XIX, May, 1897. pp. 351-64).

 (ibid., p. 27). In October, 1891, Dr. Keyes recogr 

 Oklahoman and Cimarron as the two closing series 

 4 th ser.. Vol. XII, pp. 306. 309), stating that "The

(Am. Grol. Vol. XXVIII, p. 302.) It will be seen that the Oklahoman series, as precisely 

 defined above is identical with the Big Blue series proposed by Dr. Cragin in 1896. and 

 therefore his name, which has priority, is adopted for this classification. In my revision the 

 only ch; nge from Professor Cragin's classification of the Big Blue series is lhal the Neosho 

 member at its base is put in the Missourian series. The Biazo* series proposed b> Prof. Hill 

 in 1902 ( twenty-first Attn. Kept. V. S. Geol. Surv. Pt. VII, p too) for ihe Red Beds Is 

 appatentl. the same as the Cimarron series of Cragin. 



4 •' M issounan " was proposed as the name of a series by Dr. Keyes. in July, 1896 

 (Am. Geol.. Vol.XVlII. pp. 2S-27). This was an ouigrowlh of the Missouri stage or for- 

 mation which was p.oposed by him in 1893 t/owa Geol. Surv., Vol. 1, pp. 85. 114; and 

 Mon. Rev. Iowa Weather Serviee. Vol. IV. p. 3). 



5 Nearly three years later Professor H. S. Williams gave the name " Chapman sand- 

 stone" to a formation occurring in northeasletn Maine < Am. Jour. Sei.. 4th ser., March, 

 1900, Vol. IX. pp. 203. 205, which was more fully described in Bull. U. S. Geol. Sum., No. 

 165, 1900, p. 78I. 



Ml is not probable that "Harper sandstone" can be retained for this subformation, 

 because the very similar tetm ol " Harper's shale" was published by Keiih two years earlier 

 as the name ol a formation occuriing near Harper's Feriy (Geologic Atlas United States. 

 Harpers Ferry folio (Folio 10), r894, pp. 3. 5>. 



7 The tetm "Wellington shales " apparently applied tothis formation, first appeared in 

 an article by Professor t-ragin, in the Kansas Cit, R.vi.wo, Sei.uee and Industry. Vol. 

 VIII, April. ,895. p. 679; and a little later he published il in the Bull. Washburn College 

 Laboratory 0/ Natural History, Vol. I, May (?), 1885, p. 86.
