3rd. — Plastic Clay (“Schlier” of the Vienna Basin), with a thick- 
ness of 180 feet, abounding with Nautilus Aturi, Bast. ( Naut . diluvii, 
Sism.), Pecten denudatus, Reuss, and Pecten, sp. nov. 
B. “ Bormidian-Aquitanian.” 
Ist. — Pecten-beds, answering to the Schio-beds, finely arenaceous, 
soft, with an abundance of small Echinidce and Pectines (P. Haueri, 
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. Cotuposed 
of detritus of Nulliporse and Polyzoa ; hard and compact. The 
characteristic organic remains are small Scutellce, identical with 
those of Schio, gigantic Orbiculince 1 and Orbitoides, some four 
inches in diameter. Shells are abundant; mostof them are analogous 
to those of Castel-Gomberto and Sangonini ; but some are of the 
Miocene type, such as Turritella cathedralis. 
II. — Note sur les Depots Cretaces lacustrks et d’eau 
Sooiatre du Midi de la France, par M. Ph. Matheron. 
(Bulletin de la Societe Geologique de France, 3 e s6rie, vol. iv. 
pp. 415-428.) 
T HE 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 Matheroniana, the lowermost 
bed of the Senonien, as a base-line, there follow in ascending Order 
in the Department of Bouches-du-Rhöne, zone of Ostrea acutirostris, 
the littoral beds with Cassiope Coquandiana, braekish-water beds, 
Fuveau series, Rognac series, and the large series of red claystones. 
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. 1 — B.B.W. 
III. — Records of the Geological Survey of India, Vol. IX. Pt. 4. 
C ONTAINS on p. 154 a notice of the discovery of the remains of 
a Plesiosaurus in the Umia (Tithonian and Portlandian) beds 
at Burroria, 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 almost 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 Orbiculina is not noticed in Geol. Mag. Yol. III. p. 152, as a Maltese fossil. —

2 M. Hebert (Bull. Geol. Soc. de la France, 3 e Serie, vol. iii. p. 595) had classed 
the Garumnian beds as Upper Senonian, and the Rognac beds as Hamien (?).
