In a visit to some of the moraines on the south side of the Alps, 

 the author's attention was drawn to certain Tertiary beds under- 

 lying the glacial deposits at Ivrea, and near the Lago d'Orta at 

 Boca, Maggiora, and especially at Buccione, south of Orta, and 

 close to the southern extremity of the lake. Here there is a small 

 remnant of micaceous sands containing older Pliocene marine fossils. 

 The species have been determined by Dr. Gwyn Jeffreys, and a list 

 was appended to the paper. The patch of Pliocene beds has appa- 

 rently been protected by the porphyritic mass on which the old tower 

 of Buccione stands ; the remainder of the Tertiary strata, which for- 

 merly must have extended northward to the Soce Valley, have been 

 swept away by the ice of the glacial period. 



The deposits at Boca and Maggiora were also described in some 

 detail. They are probably newer Pliocene. 



Near Ivrea the most interesting section seen was at Strambinello, 

 on the banks of the Chiusella. Here on both banks of the stream 

 horizontal Pliocene beds, containing marine shells, are exposed rest- 

 ing on diorite. On the south bank the Pliocene is broken up and 

 mixed with diorite fragments. Moraine overlies the Pliocene. 

 The great Dora Baltea glacier swept across the gorge of the Chiu- 

 sella, and only left a remnant of the marine beds where protected 

 by the ravine. 



The Pliocene sea probably extended along the south base of the 

 Alps, extending in long gulfs up the valleys, out of which the 

 marine deposits have been swept by the ice, except in a few pro- 

 tected spots. 



The paper concluded with a notice of some fossiliferous gritty 

 marl seen in a ravine close to Dormiletto on Lago Maggiore. Al- 

 though probably in situ, the mass was not sufficiently exposed to show 

 its relations to the surrounding rocks.
