3rd.— P/asif«'c Clay ("Schlier" of the Vienna Basin), with a thick- 

 ness of 180 feet, abounding with Nautilus Aturi, Bast. {Naut. diluvii, 

 Sism.), Pecten denudatus, Keuss, and Pecten, sp. nov. 

 B. " Bormidian- Aquitanian." 



1st. — Pecten-heds, answering to the Schio-beds, finely arenaceous, 

 soft, with an abundance of small Echinidce and Pectines {P. Uaueri, 

 and P. deletus) ; the chief building material of Malta. 



2nd. — Lower Limestones, chiefly developed in Gozo, visible in 

 Malta for longer or shorter distances along the coast. Composed 

 of detritus of Nullipor^e and Polyzoa ; hard and compact. The 

 characteristic organic remains are small Scutellce, identical with 

 those of Schio, gigantic Orhiculince^ and Orbitoides, some four 

 inches in diameter. Shells are abundant ; most of them are analogous 

 to those of Castel-Gomberto and Sangonini ; but some are of the 

 Miocene type, such as Turriiella cathedralis. 



II. — Note sur lks Depots Cretaoes lacustres et d'eau 

 SouMATRE Du MiDi DE LA France, par M. Ph. Matheron. 

 (Bulletin de la Societe Geologique de France, 3^ s^rie, vol. iv. 

 pp. 415-428.) 



THE author is of opinion that the beds of fresh and brackish water 

 deposits that occur in Central France, and which were at one 

 time considered to be entirely of Miocene age, represent not only 

 almost all the Tertiary series, but even some of the uppermost beds 

 of the Chalk. 



Starting at the Chalk with Ostrea Mather oniana, the lowermost 

 bed of the Senonien, as a base-line, there follow in ascending order 

 in the Department of Bouches-du-Rhone, zone of Ostrea acutirostris, 

 the littoral beds with Cassiope Coqiiandiana, brackish-water beds, 

 Fuveau series, Rognac series, and the large series of red clay stones. 

 All these M. Matheron classes as Cretaceous ; all above being referred 

 to the Tertiary period. The "terrain Garumnien" of M. Leymerie is 

 correlated with the two last named of the above series, i.e. uppermost 

 Cretaceous.''— B.B.W^

I'^ONTAINS on p. 154 a notice of the discovery of the remains of 

 \J a Plesiosaiiriis in the Umia (Tithonian and Portlandian) beds 

 at Bun'oria, in Kachh. 



The specimen, which is the first indication yet found of the presence 

 of this reptile in India, "comprises the whole of the symphysis and 

 small portions of the rami of the mandible ; on the right side it 

 contains the alveoli of five teeth, and on the left side, of four." It 

 " agrees alm-ost exactly in form and size with P. dolichodeirus of the 

 Lias." This interesting specimen, which doubtless will not long 

 remain unique, was found by Mr. A. B. Wynne, and is described 

 by Mr. R. Lydekker, of the Indian Geological Survey. — B.B.W. 



1 Orhiculina is not noticed in Geol. Mag. Vol. III. p. 152, as a Maltese fossil. — 

 Editor. 



- M . Hebert (Bull. Geol. Soc. de la France, 3^ serie, vol. iii. p. 595) had classed 

 the Garumnian beds as Upper Senonian, and the Eognac beds as Damien (?).
