Fusulina cylindrica, Fischer, Oryct. Moscow, p. 126, p. 18, figs. 1-5. 
In Russia this species is said to occur only in the upper part of lower Carboniferous or mountain limestone. Yet 
the species usually referred to F. cylindrica in this country, so far as our knowledge extends, is not found below 
the Coal measures. From this fact, and some slight differences we observe between our specimens and the figures 
of the Russian species, we suspect a careful comparison of good specimens may possibly prove them to be distinct. 
Ranges in Kansas from Division No. 22, of the foregoing section, far down into the Coal measures. Found at 
numerous localities between Manhattan and the Missouri, usually in great numbers. Also occurs in vast numbers 
in the southwestern part of Iowa and in Missouri. Dr. George Shumard has discovered a remarkable species of 
Fusulina in the white limestone of the Guadalupe mountains upwards of an inch in length, which he considers 
distinct and has been named by his brother F. dontjaia. 
Fusulina cylindrica , var. ventricosa, Meek and Ilayden, Proc. Acad. Nat. Sci. Phila. December, 1858, page 
201. Division No. 87 of foregoing general section, at Manhattan on the Kansas, and at Juniata on Big Blue river. 
Bryozoa. 
Synocladia liserialis. Prof. Swallow refers this species with doubt to S. virgidacea, Phillips, sp. in Transactions 
Acad. Sci. St. Louis, vol. i, p. 179, and points out some of the characters in which it differs, stating at the same 
time, in case it should prove to be distinct, that liserialis would be a good specific name for it. We regard it as 
quite distinct from Phillips’s species, not only in scarcely ever having more than two rows of cellules, but also 
because the ? gemuliferous vesicles, instead of being merely “tubercular and open at the summit,” have the form 
of short, but distinct spines, apparently closed and rather obtusely pointed at the apex. The branches or connecting 
process are likewise less distinctly angulated between the longitudinal stems than in S. virgulacea.. Occurs at 
Fort Riley in No. 19 of foregoing general section, and at various lower horizons on the Kansas below there, down 
into the upper Coal measures. 
Acanthocladia Americana. In the Trans. Acad. Sci. St. Louis, vol. i, p. 180, Prof. Swallow refers this species 
with a query to A. anceps, Schlot. sp. and remarks that it differs from that species in having “ the rows of cellules 
diagonal to the axis of the stems, instead of longitudinal, as represented by King, and on ridges like that figured 
by Goldfuss.” He also further remarks that “ it is less regularly branched, and not so distinctly pinnated as those 
delineated by Goldfuss and King.” In the specimens in our collection, the cellules are more numerous and much 
more crowded than in A. anceps, as figured by King. The specific name Americana, was suggested by Prof. 
Swallow. 
We found this species in Division No. 18 of the foregoing general section, on Cottonwood creek. 
Echinodermata. 
Cyathocrinus - ? A few scapular plates, bearing some similarity to those of C. ramosus, Schlot. sp. were met 
with by us in Division No. 18, but they are proportionably much thicker, and the articulating surfaces quite 
different. Cottonwood creek. 
Archcvocidaris - ? In No. 12, we found spines and detached plates of apparently an undescribed species of 
this genus, but they were too much weathered to show clearly the specific characters. The spines are rather 
slender, terete, nearly straight, and provided with short scattering spinous processes, directed rather obliquely 
outwards and forward. Cottonwood creek. 
Archceocidaris - - ? The spines of this species are much larger than the last, and apparently destitute of
