local surface, which in this place seemed to have been excavated by rain.* 
From this neighbourhood the alluvium rapidly becomes thin to the east, and although it 
does not possess any marked, natural boundary, it is seen to grow narrow towards the south, 
the trap country approaching the coast and the plain becoming dotted witli hills all formed 
of trap. High ranges of hills are seen away to the east and south beyond the limits of our 
district and trap rocks occur in all the rivers. Some of thp isolated trap hills rise to a con¬ 
siderable height. That at Parneira, the most conspicuous among them, roughly measured 
by a barometer is at the summit nearly 200 feet above the plain at its base, but it looks much 
higher. The trap of this country does not differ from that stretching along the whole of 
the east side of the district, and although it is not to be seen everywhere, there is no want 
of evidence to show that the whole country is composed of it. Dykes are perhaps more 
numerous than in several other parts of the district: where the Kailway crosses the 
Da maun river and where there are a great number, their general direction approximates 
to north and south. 
From near Teetul on the coast west of Bulsar and re-appearing at intervals to the 
south, is a growing deposit of recent conglomerate formed of the materials of the beach 
cemented by carbonate of lime; it is stratified, the strata dipping at a low angle seawards, 
and the dead shells which it contains have been in many instances completely fossilized and 
replaced by carbonate of lime even when they happened to be a large variety of Murex, whose 
shell is very thick; but in few instances, if any, was the interior of the shell filled up by 
either sand or the cementing matter. 
Additional observations regarding the cephalopodous fauna of the South Indian 
cretaceous deposits, by Ferd. Stoliesha , Esq., Ph. D., Palaeontologist, Geol. Survey, 
India. 
Since the completion of the volume on the Cephalopoda of the cretaceous rods of 
Southern India, fat the end of 1865, several additional observations have been made regarding 
this portion of the fauna. No fresh materials have been procured, but having had last year 
the opportunity of examining, in London, Prof. Forbes’ original collection, made by Messrs. 
Kaye and Cunliffe, and also in different European Museums a large number of other species 
with which Indian Cephalopoda have respectively been identified, I have obtained additional 
information of various kinds. Some of this is very important, inasmuch as it throws a new 
light upon the determination of the species, requiring alterations in the names, &e.; it appears, 
therefore, desirable that these changes should be noticed at an early date. The observations 
must be considered as a supplement to the volume on the Cephalopoda, already published.

NAUTILUS, Auctorum. 
Nautilus danicus, Schlotheim. —(Ceph. 1. cit., p. 24 and 208). 
Nautilus delphmus, Forbes (Trans. Geol. Soc., Lond., 1846, VII, pp. 98 and 99), which 
was described from two specimens in Messrs. Kaye and Cuuliffe’s collection of Pondicherry 
fossils, must be considered as identical with the above species. Forbes’ figure on p. 99 is 
reduced to one-half the natural size, bemg taken from a larger specimen, which is, however, 
veiy much corroded at the surface. In consequence of this erosion the outline of the septa 
became rather different and the thickness of the whorls has decreased. Both the specimens 
and also some others in our collection appear to have had originally the whorls somewhat 
more flattened laterally than typical Naut. danicus usually have them, but there are again 
in our collection some other specimens which fully agree with Sowerby’s original figure in 
Trans. Geol. Soc., Lond., 1840, vol. V, pi. 18, figs. 4-7. Another apparent distinction of 
* There appeared to be no trace of a burial ground on the bank of the river here, and the lower extremities 
pointed in the direction in which the stream runs, but as the natives of India are often buried near wherever they 
happen to die, while some castes bring dying people to the rivers, it is thought more safe merely to record the fact, 
than to build any geological theory upon so questionable an occurrence,
