.Rhadocarz¢<s sp. cf. multistriatus (Presl.) Lx. 
This single large seed is very poorly preserved. The charac- 
ters of the specimen are poorly marked, possibly because of a 
non-resistant testa. The endotesta, or sarcotesta, surrounding 
it during life leaves its imprint of carbonaceous matter around 
the sides. Neither ribs nor striz show on the testa, the whole 
being covered with a smooth carbonaceous layer. 
This seed is very similar to a large seed from Clinton, Mo., 
with which I have compared it. The Clinton seeds are referred 
doubtfully by White to Rhabdocarpos multistriatus. 
Formation and locality: Cherokee shales, Lansing. 
Rhabdocarpos cf. emarginatus Lx. Pl. XLVII, figs. 1, 2. 
The Le Roy shales contain at the Blue Mound and Haver- 
kampf localities numerous seeds which are oblong in form, 
obtuse at the apex, narrowed to a short, thick, neck-like attach- 
ment at the base, 2 to 214 em. long, about 1 cm. wide, marked 
with numerous fine, more or less broken, striz. 
Formation and locality: Le Roy shales, Lawrence. 
Cardiocarpon BRONGN. 
Cardiocarpon Brongniart, Prodrome, p. 87 (pars), 1828. 
Cardiocarpon sp. PI. LI, figs. 12, 18. 
Innumerable small seeds of the genus Cardiocarpon are 
found at the Haverkampf locality, one stratum being almost 
completely filled with them. They are almost orbicular in out- 
line, slightly pointed at the apex. The specimen illustrated by 
figure 138 of plate LI is more pointed than is usual. This seed, 
lying in a concretion, still has the petiole by which it was at- 
tached preserved. The seeds are thin and flat, the nucleus in- 
distinct, and often distinguished with difficulty. 
Formation and locality: Le Roy shales, Haverkampf farm. 
Sa eon (Samaropsis) branneri Fairchild and D. W., Mss. PI. LI, 
The phase of this species in the Bethany Falls limestone at 
Kansas City, Kan., is so similar to the species as found in the 
Cherokee shales at Clinton, Mo., and so well described by David 
White (Flora of the Lower Coal Measures of Missouri, p. 266) 
that I quote his description: “Fruit small, oval or ovate, and 
slightly prolonged at the somewhat truncate base, 10 to 12 mm. 
long, 7 to 9 wide, consisting of an ovate nucleus within a rela- 
tively wide wing; wing oval, blunt, and incised a little, or very 
slightly emarginate at the apex, sometimes slightly rounded on
