5. CiRRATRiRADiTES (?) GRACILIS (Zcrndt) 



S. W. and B., comb. nov. 



Triletes gracilis Zerndt, 1937, Acad. 

 polonaise sci. Bull, internat., ser. A., p. 586, 

 pi. 12, figs. 1-10. 



Type 46 Zerndt, 1937 (idem). 

 Note — Species exceptionally large (300 ti) , 

 otherwise in close generic agreement. 



6. CIRRATRIRADITES MACULATUS WilsOU and 



Coe, 1940, Am. Midland Naturalist, vol. 



23, no. 1, p. 183, fig. 7. 

 Note. — Reexamination of the type material 

 suggests the trilete apex is ordinarily normally 

 developed and that the apical opening originally 

 described is not of general occurrence. Sculp- 

 turing simulating it may occur distally.

 rahim, Loose, 1934, Inst. Palaobot. Arb., 

 vol. 4, no. 3, p. 149, pi. 7, fig. 23. 

 A^of^.— Ibrahim (1933) came to the conclusion 

 that Sporonites formosus Ibrahim (1932) was 

 conspecific with C. saturni. Very little infor- 

 mation is provided to support this and, since 

 the figures appear to show specific differences, it 

 appears desirable to keep them separate for a 

 time at least.

B., comb. nov.

Genus Endosporites Wilson and Coe,

Plate 2, figures 14-14b 



Symmetry. — Spores trilete, radial. 



Shape. — Moderately flattened elliptical 

 in transverse plane, in axial plane round 

 to oval or elliptical or slightly triangular ; 

 body wall more spherical than the bladder. 

 When compressed the spores most com- 

 monly shov^ good proximo-distal orienta- 

 tion. The spore body is not generally 

 folded but the bladder membrane more 

 commonly shows irregular plication. The 

 bladder profile at the margin of the spore 

 corresponds to the profile of folds, being 

 straight or evenly rounded, and thus 

 easily distinguishable from simple flanges 

 of zonate forms that superficially re- 

 semble Endosporites, 



Size. — Ranging in various species from 

 about 50 to possibly 300 microns total 

 diameter. The spore body generally is 

 less than one-half of the full diameter. 



Ornamentation. — Surfaces of bladder 

 are levigate to granular or punctate ; a 

 fine meshed reticulation pattern is com- 

 monly present but this is probably on the 

 inside, rather than on the external bladder
