to HeUcotoiiKf. OphiU'ta (ilfKreusis, Riipliishnna iitiiinesotense and 
B. oweni are doubtless congeneric, and if one is an Ophileta the other 
two are also. Whatever position they may occupy ultimately it is cer- 
tain that they are quite distinct from Rdphistoma. Of the five species 
referred to the latter genus by Mr. Sardeson, only one, R. ruidum, 
Ijrobably belongs here. The SintparolluH intnilobaius we would call an 
EceyliomplialuH with contiguous whorls. SuhiiliteH (^rac/ /f.s should have 
been compared with S. calciferns Billings. Like that species, it is a 
Fasispira and not a Subulitea. e. o. u. 
The Fauna of the Camhriau. of Tejrovic and SkreJ in Boliemia. By 
J. F. PoMPECKJ. (Jahrbuch der k. k. geol., Reichsanstalt, 1895, 45 
Band, 3 Haft.) We owe to Dr. Pompeckj's pen a very full and lucid 
account of the Cambrian strata and fossils of the above localities in 
Bohemia. The clay slates of the Paradoxides beds pass downward, 
after the intervention of a sandstone bed and felsites, into conglomer- 
ates and sandstones, in the lower part of which another Cambrian 
fauna has been detected. These rest upon porphyry and diabase which 
overlie graphitic clay-slate, the true Etage "B." 
It would seem from this essay that a part of Barrande's Etage B is to 
be referred to the Cambrian, there being a discordance in this stage, 
and the upper part containing a Cambrian fauna. 
The Etage C has been divided by the Bohemian geologists, who find 
two subfaunas of Paradoxides, the upper of which is the primordial 
fauna as known to Barrande [though he was acquainted with a number 
of species that come from the lower subfauna]. The lower subfauna 
contains Paradoxides riigiilosun, the upper P. hohemi can (cf P. tiHsini). 
A Lower Camin-ian fauna is referred to the Olenellus grouping, 
though the genus has not been recovered from it. but the crustaceans 
that do occur are of different species from those of the Paradoxides beds 
above and some genera are different. 
A full description of these faunas is given by Dr. Pompeckj, and a 
number of new species are described. 
The cystidians are well represented and a new genus, St)-o)nato rys- 
tifes, is described. 
The brachiopods are represented by four genera: the Olxdus ('/} bo- 
heniicHs of Barrande is referred to Acrothele and another species of this 
genus described.* A minute species of Acrotreta, near A, soci(dis v. 
Seebach, is described, and a Lingulella. Two species of Orthis, one of 
the "Middle Cambrian" (Paradoxides bed) O. roinivgeri Barr.,t the 
other in several varieties from the Lower Cambrian (Olenellus zone). 
Five species and one variety of Agnostus are cited; the species were 
described by Barrande. 
The species of Paradoxides and Hydrocephalus were described by 
Boeck, Corda and Barrande, except one, which is claimed as new (P. 
jahni); this species is quite like Hydroeephnhis satnrvoides Barr. Dr.
