Stefani> C. de. Lc rocce scrpcntinose della Garfagnana. [Serpentine 

 of Garfagnana District.] Boll. M. Com. geol. Ital. t. vii. pp. 16- 

 31 ; 3 woodcuts. 



Shows that the serpentine of the Apuan Alps is not Propaleeozoic or 

 Laurentian. While in Elba, Corsica, &c. the serpentine rocks are 

 older than the Infra-lias, but not older than the Carboniferous, here 

 they are either Cretaceous or more frequently Eocene. The serpentine 

 of the basin between the Apuan Alps and the Apennines is accompanied 

 with gabbro and diabase, but mingled with them are sedimentary rocks. 

 In the Garfagnana they are U. Eocene, being associated with the alberese, 

 and lie above the macigno [M. Eocene], never being found intrusive in 

 it. Similar rocks of the Lunigiana and maritime Liguria are probably 

 of the same age. The serpentine was probably poured out over the 

 bottom of the U. Eocene sea. E. B. T. 



Sedimenti sottomarini dell' epoca postpliocenica in Italia. 



[Marine Post-pliocene Sediments, &c.] Boll. JR. Com. geol. Ital. 



t. vii. pp. 272-289. 

 Although Post-pliocene land-deposits are known in Italy, no con- 

 temporaneous marine beds have been commonly recognized. Prom a 

 criticism of the molluscan fauna frOm various localities the author 

 establishes a proof of cold climate in the sea, and therefore of the glacial 

 age of such. Por example, beds at the new docks, Leghorn, yielded 

 ] 33 species, of which only 4 are extinct [ = 3 per cent.] ; in other cases 

 the proportion was about 11 p. c. [whereas in Pliocene beds it varies 

 from 25 to 50 p. c] ; the presence of Cyprina Islandica in all these 

 cases is also confirmatory of a cold and Post-pliocene climate. In- 

 stances specially analyzed are deposits at Monte Pellegrino and Pica- 

 razzi, near Palermo, Sciacca and Carrubbare, near lieggio, Calabria ; 

 even those of Yallebiaia and the upper beds of Monte Mario with C. 

 Islandica are considered Glacial [usually called TJ. Pliocene). E. P. T. 



Stoehr, E. [Section at Girgenti, &c.] Zeitsch. deutsch. geol. Ges. 

 Bd. xxviii. Heft 3, pp. 650-654. 



Notice of a section near Girgenti which shows a continuous confoi^m- 

 able series from the latest Tertiaries down to the Sulphur-formation ; 

 the divisions are grouped as U. and M. Astian, Messinian, and under- 

 lying cavernous limestone. E. B. T. 



II terrene pliocenico dei dintorni di Girgenti. [Pliocene of 



Girgenti.] Boll. R. Com. geol. Ital. t. vii. pp. 451-474, plate (sec- 

 tions). 

 Classifies the divisions of the Pliocene in this district under P'pper 

 (Astigian), consisting of 4 subdivisions, and Lower (Messinian). The 

 conditions under which they were deposited are deduced from the fossils 

 found. The fauna is separately catalogued [8 pp.], and compared with 

 that of other Italian fossil localities, as well as with the llecent period. 

 In the U. Pliocene 197 species are noted ; out of 131 MoUusca, only 27 

 are extinct. The second table is a list of 60 Foraminifera. E. B. T.
