large lobe of the glabella in front of the eyelobe excludes it from 
Remopleurides. 
Triarthrus jemtlandicus is a species with obscure glabella and 
wedge shaped front to the middle piece of the headshield. 
4. Paradoxiccs jemtlandicus is a many jointed species (19 plural 
segments) which was found in the Elandicus' zone. The second and 
the last segment are larger than the others, and the rachis of the py- 
gidium has but a single joint. 
5. A new species of trilobite from the Dictyonuna shale is de- 
scribed, Boeckia mobergi The pygidial spines are more approximate 
than in B. hirsuta. 
6. Couularia munthci, is a new species of the monolifera division 
of Holm, the segmental line of the pyramidal face is trip'e, the form of 
the shell and sculpturing of the surface are described. A plate of fig-

Ueber das neve Vorkommen einor untersilurischen Fauna bci Lhotka 
{Mittelbohmen) . J. V. Zelizko. 
Herr Zelizko in this communication gives the result of his examin- 
ation of a lot of fossiliferous rock from the Band d, y sent him by 
professor J. J. John of Briinn for study. It came ( rom a new locality 
at Lhotka in middle Bohemia and gives some interesting results. 
The locality had been visited by Dr. J. Perneo, who had announced 
it at a meeting of the Bohemian "Landes-museum, and had mentioned 
the occurrence there of a number of Barrande's species and one new 
species of Bellerophon, B. aims, of the sub-genus Salpinostoma. 
In the material sent to professor Zelizko he found quite a num- 
ber of species which had not been reported by Perneo, Lome of which 
had not been previously known from this band. 
The following trilobites were found in Dr. Jalm's material : Pla- 
coparia Zippei, Bceck, sp. Aeglina princcps Barr ; Acspcciosa, Corda, 
sp. A. prisca Barr. Dalmania atava, Barr., D. sp. Asphus nobilis. Barr., 
Ogygia, sp. Ascidaspis Buchi, Barr., Illcnus Saltcri, Barr., /. Panccri, 
Barr., Trinuclus, sp. 
Of Cephalopoda, Orthoceras, sp. Of Brachiopoda, Pater u'a b )he- 
mica, Barr., Discina, sp. Of Gasteropoda, Pleurotomaria sp. Of Con- 
ularidse, Couularia bohemica, Barr., C. proteica, Barr., Heyalithes 
elegans, Barr., H. indistinatus, Barr., Hyolctluts, sp. Of Lamellibranch- 
iata. Filius antiquus, Barr.. Xucula faba Lcda bohemica, Barr. Of 
Crinoidea, Entrochus primus, Barr. Encrinitcs sp Of Cystidians, An- 
omalocystitcs, sp. Of Hydrozoa, Dcsmograptus, sp.. Ptyograptus ra- 
male Pocta. 
It will be observed that Dr. Zelizko classes Hyolithes with the 
Cenulariae, notwithstanding the adverse views of Holm and others. 
A- in his classification of the species found Zelizko arranges Hyolithes 
between Gasteropod and Lamellibranchs, one may suppose that he leans 
to the view of Xaumayr that they are related to the "snails.'' i.e. Gas- 
teropods; but the structure of the operculeun is quite different from 
that of any Gasteropod. Sir William Dawson has calhd attention to
