mond-drill core (NE. \/ A NE. \/ A NW. ]/ 4 

 sec. 18, T. 7 S., R. 10 E., White County) 

 at 108 feet to 1 14 feet has been thought to be 

 the New Haven. Unfortunately no coal is 

 present below the limestone but a hydro- 

 fluoric maceration of black shale has yielded 

 a few spores which do not suggest a relation- 

 ship with the New Haven coal bed. Thus 

 the stratigraphic position of this bed based 

 on plant spores is uncertain. 



The following genera and species have 

 been observed from this bed : 



1. Punctati-sporites setulosus sp. nov. 



2. P. obliquus sp. nov. 



3. P. orbicularis sp. nov. 



4. P. sulcatus Wilson and Kosanke, 1944 



5. P. grandiverrucosus Kosanke, 1943 



6. P. sp. 



7. Granulati-sporites commissuralis sp. nov. 



8. Alati-sporites punctatus sp. nov. 



9. Reticulati-sporites muricatus sp. nov. 



10. Laevigato-sporites obscurus sp. nov. 



11. L. robustus sp. nov. 



12. L. minutus (Ibrahim) S. W. and B., 1944 



13. Endosporites formosus sp. nov. 



14. Triquitrites sp. 



15. Calamospora sp. 



16. Reinschospora triangularis sp. nov. 



17. Raistrickia sp. 



Laevigato-sporites, with about 30 percent 

 of the spore population, is the most abun- 

 dant genus. L. obscurus sp. nov. represents 

 23 to 24 percent of the spore population and 

 thus the remainder of the species of the 

 genus is not abundant. Punctati-sporites 

 with 22 to 24 percent of the spore popula- 

 tion is next in numerical importance. P. 

 grandiverrucosus Kosanke, 1943, and P. 

 orbicularis sp. nov. represent nine and seven 

 percent respectively, and the remaining 

 species are not of numerical importance. 

 Reticulati-sporites muricatus sp. nov., Alati- 

 sporites punctatus sp. nov. and Reinscho- 

 spora triangularis sp. nov. represent 14, 12, 

 and 12 percent, respectively, of the spore 

 population. The remaining genera and 

 species are rare. 



McCleary's Bluff Coal Bed 



The name McCleary's Bluff is used here 

 to designate a three-inch coal bed exposed 

 along the Wabash River Bluff in the NW. 

 i/4 SW. 14 SW. 14 sec. 29, T. 2 S., R. 13 

 W., Wabash County. The stratigraphic 

 position of this bed is uncertain although 

 it appears to lie below the Friendsville coal 



bed. This bed is included because many 

 excellently preserved spores were present, 

 five of which serve as types. The following 

 forms have been observed in this bed at the 

 above mentioned locality: 



1. Punctati-sporites setulosus sp. nov. 



2. P. orbicularis sp. nov. 



3. Granulati-commissuralis sp. nov. 



4. G. grandis sp. nov. 



5. G. levis sp. nov. 



6. Laevigato-sporites latus sp. nov. 



7. L. ovalis sp. nov. 



8. L. minutus (Ibrahim) S. W. and B., 1944 



9. L. desmoinensis (Wilson and Coe) S. W. 

 and B., 1944 



10. L. minimus (Wilson and Coe) S. W. and 

 B., 1944 



11. Endosporites formosus sp. nov. 



12. Triquitrites sp. 



13. Calamospora hartungiana Schopf, 1944 



14. C. sp. 



15. Raistrickia aculeata sp. nov. 



16. Wilsonia sp. 



17. lllinites elegans sp. nov. 



18. /. sp. 



Laevigato-sporites accounts for 66 to 68 

 percent of the spore population, and L. 

 ovalis sp. nov. and L. minutus (Ibrahim) 

 S. W. and B., 1944, each average about 30 

 percent. Endosporites formosus sp. nov., 

 Punctati-sporites orbicularis sp. nov., and 

 Calamospora represent 12, eight, and eight 

 percent of the spore population, respectively. 

 lllinites elegans sp. nov. which represents 

 about three percent of the spore population 

 appears restricted to this bed. 



Friendsville Coal Bed 



The Friendsville coal bed is thought by 

 Wanless (1939) to be equivalent to the 

 LaSalle or Lower Bogata coal beds. How- 

 ever, present studies indicate that it does 

 not correlate with the LaSalle coal bed, 

 maceration 600. Comparison with the 

 Lower Bogata coal bed has not been made, 

 hence its relation with the Friendsville and 

 LaSalle coal beds on the basis of spore con- 

 tent is unknown. 



The Friendsville coal bed appears to be 

 lenticular and has a known maximum thick- 

 ness of 42 inches in a mine now abandoned, 

 located in the NW. \/ A NE. \/ A NE. \/ 4 sec. 

 29, T. 2S., R. 13 W. Coal from this mine 

 and that from a mine located near Friends- 

 ville in the NW. 14 SW. 14 SW. \/ A sec. 

 13, T. 1 N., R. 13 W. contain essentially
