The Camp Supply Beds.—There can be little doubt but 
that the localities of the Cretaceous near Camp Supply reported 
by Prof. Cope,t and at Comet Creek, reported by Prof. Jules 
Marcou,{ represent a portion of the same general sedimenta- 
tion as the Belvidere beds which Prof. Cragin himself has 
reported in Northern Oklahoma. 
From the beds near Camp Supply Prof. Brown, of the 
University of Kansas, reports eleven invertebrate species, as 
follows: 
1. Gryphea§ forniculata White. 7. Plicatula incongrua Cragin. 
2. Exogyra texana Roem. 8. Trigonia emoryii Conrad. 
3. Ostrea|| subovata Shum. 9. Trigonia sp. . 
4, Ostrea quadriplicata Shum. 10. Turritella seriatim granulata 
(variety). Roemer. 
5. Cucullea terminalis Conrad. 11. Schleenbachia peruvianus 
6. Neithea occidentalis Conrad. von Buch. 
Of the nine species named, the following have been reported 
from the Belvidere shales of Kansas : 
1. Exogyra texana Roemer. 5. Turritella seriatim granulata 
2. Grypheea forniculata White. Roemer. 
3. Trigonia emoryii Conrad. 6. Schlenbachia peruvianus von 
4, Cucullza terminalis Conrad. Buch. 
The following are characteristic species of the Washita 
division of Central Texas: | 
1. Gryphea forniculata White. 5. Trigonia emoryii Conrad. 
2. Ostrea subovata Shum.4 6. Schleenbachia peruvianus von 
3. Ostrea quadriplicata Roemer. Buch. 
4, Plicatula incongrua Conrad. 
The following species are common to the Fredericksburg 
and Washita divisions of Texas: 
Neithea occidentalis Conrad. Schlenbachia peruvianus von 
Turritella seriatim-granulata Buch. 
Roemer.

§ Originally published as G. pitcheri Morton. Prof. Brown informs me by 
letter that 1t is the form figured by Marcou, i. e. G. forniculata White. 
|| Originally published as O. crenulimargo Roemer by Prof. Brown. He informs 
me that he now regards it a variety of Ostrea quadriplicata Shum. 
4] See remarks on this species by Dr. Benj. F. Shumard, Trans. Academy of 
Science of St. Louis, vol. i, p. 587. He here states that its horizon is the Washita 
limestone and gives more light upon it than is contained in his original descrip- 
tion of it in Marcy’s Report on Red River.
