glomerates in the Pusterthal district are supposed to be of this age. 

 The South-Tyrol porphyries and tuffs belong to the Permian. 



In the chapter on tectonic or structural relations, the Pusterthal 

 quartz-schist group is said to be essentially a system of several leading 

 faults with an E.-W. direction and an inclination S. of 80°-45°, 

 bringing into their midst sometimes older masses (gneiss or mica- 

 schists), sometimes newer beds of the greywacke type (Kalkthon- 

 phyllitgruppe). A complete digest of the literature of the subject is 

 added. E. B. T.

Moraine-deposits were found in the valley of the Sauro, between 

 Modena and Castelnuovo ; the rock from which the boulders were de- 

 rived was found in place at the Corfino Alp (Apennines), at about 4700 

 feet. Similar moraines are noticed in other valleys of the Apennines, 

 and also in the Apuan Alps. E. B. T.

Deep valleys intersect these mountains, and display their dome-shaped 

 structure ; the lowest beds seen are ochrey limestones 3-4 meti'es thick ; 

 above are crystalline schists disposed round the central nucleus ; these 

 schists include protoginic gneiss, quartzites, &c. ; the major axis of the 

 elliptical dome lies N.N.E. and S.S.W. Above, and conformable to, 

 these schists comes the Carrara-marble series ; and then follow schists 

 and flags again, which form the outer ring, being above the marble 

 series. The fossils found in the marble are imperfect specimens of 

 Chemnitzia &c. ; they may be Triassic, but the age is still doubtful ; 

 they are, however, certainly older than lihaetic. 



In the Monte- Pisano district the upper schists form the central 

 nucleus, contrary to what occurs in the Apuan Alps, and the axis lies 

 N.W. by S.E. Above these upper schists are grey limestones, fre- 

 quently with fossils, and identical with the Spezia beds of Infra-Liassic 

 age ; they form a continuous circle on the outer flanks of both districts ; 

 this rock is frequently cavernous or dolomitized, and in this case was 

 by previous observers generally classed as Triassic. E. B. T.
