either side of the micropyle, near which it forms a border 2 to 
2.5 mm. in width, narrowing slightly downward toward the lat- 
eral angles of the nucleus to 1.5 to 2 mm. in width, then pro- 
longed or dilated in a basal lobe 3 to 5 mm. wide, extending 
3 to 5 mm. downward and truncate, or truncate rounded at 
the base, which is often traversed by a fine, clear line passing 
downward from the nucleus; nucleus ovate triangular, usually 
rather obtuse just below the acuminate apex, generally uni- 
form in size, about 7 mm. long, 5 mm. wide, broadest a little 
below the middle of its altitude, either very obtusely rounded 
or truncate at the base, very thinly lenticular in cross-section, 
thickest near the base, or, when flattened, often marked by a 
small oval median convexity above the base, above which a 
line or faint ridge passes upward to the micropyle.” To this 
description I may add that extra-well preserved specimens 
show that the nucleus was covered in life by numerous close- 
set, short, stiff, bristly hairs, which have a tendency to 
take a direction obliquely across the nucleus, and away from 
the thin line running from the base of the nucleus to the micro- 
pyle. This species resembles C. zonulatus Lesqx. in its general 
shape and size. It may be readily distinguished, however, by 
the greater downward extension of the bordering membrane at 
the base. The extension of the membrane of C. branneri is 
often half the length of the nucleus itself, amounting to 3 or 
4 mm., while with C. zonulatus the membrane rarely ever ex- 
tends more than 2 mm. below the nucleus. 
Formation and locality: Bethany Falls limestone, Kansas

Aphlebia Germar (non Presl), Verst. d. Steink. v. Wettin u. Lobejun, p. 5, 1844.

p. 5, 6 
The genus Daubreeia was established by Zeiller to include a 
very unusual organism found in the Commentry Coal Meas- 
ures of France, to which was referred also a few specimens 
previously described by Germar from Wettin, Germany, as 
Aphlebia paterxformis and A. patens. The genus has not been 
previously recognized in this country.?9! The University of 
Kansas collection contains, however, a few excellently pre- 
291. Since the above was written Mr. White has mentioned (Bull. No. 211, U.S. G.S., 
p. 100, 19038) the occurrence of the genus at Onaga, Kan.
