conglomerates, at the base of the variegated sandstones with 
Myophoria costata, being a part of the lower horizou of the 
Fünfkirchen shelly limestones. Nearly one-half of these species 
are found in the Copper-shales of the Saxon and Franconian 
“ Zechstein.” Ullmannia Geinitzi and its congener U. Brauni are 
characteristic Dyasic (Permian) forms. The specimens of Voltzia 
Jlungarica, Hr., are identical with Palissya Brauni in the form and 
the distichous arrangement of their leaves, and in the form of their 
branches, and would find a better place in this genus ; the forms 
generally ranked among Voltzia having no median nerve, and the 
arrangement of their leaves being polystichous. The scales of 
strobili, possibly not connected with the branches found here, stand 
very near those of Voltzia. 
5. On the Tipper Tertiary Plants of Sieily. — Bv Dr. H. Th. Geyler. 
(Imp. Geol. Instit. Vienna, Meeting of March 6, 1877.) 
These plants, together with fossil Insects, have only been found 
in the lacustrine gypsum and sulphur-bearing beds of the hill ränge 
of Cannatone, north of Racalmuto and Grotte, in the Province of 
Girgenti. The species, denoting an earliest Pliocene origin, repre- 
sent the genera Xylomites, Furcellaria, Algacites (?), Pinus, Phrag- 
mites, Poaciles, Potamogeton, Palmacites, Myrica, Ainus, Quercus, 
Cinnamomum, Laurus (?), Diospyros (?), Cel.amstrus (?), Berchemia, 
Juglans, Ccesalpinia (?), Robinia (?), and Acacia (?). Several of 
them are identical with those from the Tertiaries of GEnino-en. 
6. On the Arctic Fossil Plants. By D. Stur. 
(Imp. Geol. Instit. Vienna, Meeting of March 6th, 1877.) 
Professor Oswald Heer has lately published the fourth volume of 
his classic “ Flora fossilis arctica,” in which he treats of the follow- 
ing localities : — 
A. Robert Valley, Research Bay, 77° 33' N. Lat., explored by 
Prof. Norden skiöld. The species collected there are — Sphenopteris 
frigida (compare Sph. bifida, Lindl.), Spli. geniculata, Germ. (Spli. 
sub-geniculata Stur (from the “Culm ”) , fiexibilis, Heer, Sph. distans, 
Stb. (an exclusively “Culmian” form), Adiantites concinnus, Goepp. 
(Ad. tenuifolius, Goepp., from the “ Culm ”), Ad. bellidnlus, Heer 
(compare Ad. oblongifo/ius, Goepp., “Culm”), Staphylopteris, sp. 
(Indusia only found in the “Culm”), Lycopodites filiformis, Heer, 
Lepidodendron Sternbergi, Brong. ( Lep.Velthemianum , St., - Gein.), Lep. 
selaginoides, St., Lepidophyllum caricinum, Heer, Stigmaria Lindleyana, 
Heer ( Stigm . inceqiialis, Goepp.), Splienophyllum longifoliim (?), 
Germ., Sphenoph, bifidum. Heer. Sphenoph. subtile (compare Sphenoph. 
tenerrimum, Ett. sp., “Culm ”), Bhynchogonium crassirostre Heer, Rh. 
costatum, Heer, Rh. macilentum, Heer, Rh. globosum, Heer, Cordaites 
palmaformis (Goepp.), Cord.borassifolius ( St.), C. principalis (Germ.), 
Walchia linearifolia, Goepp. (compare W. antecedens, Stur), Sama- 
ropsis Spitzberg ensis, Heer, and Carpolithes nitidulus, Heer. Accordimr 
to Professor Heer, this Flora is Middle Carboniferous ; the Calamites, 
Annularice, Aster ophyllites, Neuroptcridce and Pecopteridce, wanting in 
the above list of species, may have been overlooked by the collector.
