REVIEW OF RECENT GEOLOGICAL 
LITERATURE. 
Uebcr I'oroci/xfix pnntifi>nttii< Cnifjiii ( ? Aninniriftx iranli Ifill) auK der 
viiteren Kreide in Texan; by Hermann Rauff (Ncucs .FalirlMich I'iir Miii- 
iTal, otc, 1895, P.iid 1. pp. 1-15, pi. 1.) 
Robert T. Hill was the first to notice, under the name (ioiiioliiKi (188!)) 
these peculiar si)herical or ovoid bodies which, in 18!)3, he described in 
some detail as tiie cones of an araiicarian. desi.iiiialiii,i;' them as Arnii- 
cM'Htes ? wardi. In tlie latter year also, Prof. F. W. C'ragin, re.na rd i n k' 
the fossils as bryozoan. described lliem under Ihe name Forori/xfi.s pn/- 
nifornm. Dr. Raulf's analysis, based u|)on a few internal casts, sul)- 
slantiates neither of these opinions, but indicates certain sui)erficial 
similarities between the surfaces of such internal casts and representa- 
tives of the genus ReceptacuUtex. "On the sjjherical form and mosaic 
structure of the surface we cannot place much weight. They are un- 
essential similarities, for Porori/xtix shaves them with other and wholly 
distinct organisms. Hut we may ascribe some little \alue thereto, from 
tlie fact that bodies like the Recejitactilitidn' are constructed of numerous 
homomor[)hic elements (Merones), each of which cimsists of a thick- 
ened summit expanded into a plate and a longer or shorter radial, i)er- 
forated by an axial canal, and that these radials (.so far as our observa- 
tions permit us to judge) s'vell at their i)roximal ends until they rest 
against and crowd one another. Radials of quite similar form we have 
found in lieceptarulitcit, as well as in some of the Txriiaditcs." The au- 
thor ventures no further opinion in regard to the structural portion of 
these fossils, leaving this determination contingent upon the acquisi- 
tion of more complete material. .i. M. c. 
Uebcr dus Oberderon der Oxfdtjnri. [If; Die Fdiniii d(s unterderoni.seheii 
Rifflcalkes, 7. By Fritz Frech, with the a.ssistance of K. Loescii.mann. 
(Zeitschr.derdeutsch. geol (Jesellsch.. vol. 40, pp.44()-47'.t. pis. ?,0-?u, 1894.) 
This is the first instalment of descriptions of the DeMHiian faunas of the 
Corinthian Alps, whose geology has already been carefully expounded by 
Prof. Frech in various numbers of these proceedings, and. more recently 
in book form; "Die Karnischen Alixui." The si)ecies here described are 
largely gasterojiods of various genera, out of 51 species, 157 belonging to 
thisgrou|). Their variety is interesting, if not remarkable, eviticing, 
first, an abundant repre-sentation of the capulids (Plntj/eents and Flaty- 
oi^toma — DinphoroxUnna, Fischer, 10 species and v;irieties) in harmony 
with other lower Devonian or "capulian" faunas: five examples of the 
Silurian genus Iremanotiin (better Trentdtanotux); tyi)ical forms of Bel- 
leropJion, of Bucanella and O.vi/dixrtix, with re[)resentativi>s of the genera, 
Pleurotomaria, MureliixoniK, TriniKjubiria (a new genus having the form 
of a triangularh' pyramidal Sobirii/ni) EitmieplKdux, I'o/i/trcpix, 7Vor/n/n, 
Loxonema, Polyfropix, Maeroehilux, Philhedr<t, Ilorioxtoina and Turbonit-
