with which he had been enabled to contrast them. The bärgest, on 
that account, he had named T. robusta; it rivalled the gigantic 
Testudo epliippium, Günther, in size, showing affinities to it in a 
few minor characters. A smaller species, T. Sprattii, and a small 
Lutremys, not distinguishable, as far as the few remains extend, from 
the recent L. europaa, besides inany fragments of shields of tortoises 
of various dimensions, had been obtained. These Chelonians were 
found in conjunction with the remains of the dwarf Elephants and 
other members of the remarkable fauna, collected by Admiral Spratt 
and the author in the ossiferous rock-cavities of Zebbug, Mnaidra, 
Benghisa, etc. The paper contained a list of the animal remains 
hitherto recorded from the Maltese fissure cavems, including three 
species of dwarf Elephants, two species of Hippopotamus, two 
gigantic species of Myoxus, a gigantic Swan, and other animal re- 
mains ; and further, a Note on some Chelonian remains from the 
rock fissures of Gibraltar. 
2. “On the Corallian Bocks of England.” By the Bev. J. F. 
Blake, M.A., F.G.S., and W. H. Hudleston, Esq., M.A., F.G.S. 
The object of the paper was to describe the rock masses existing 
betwixt the Oxford and Kimmeridge Clays. Topographically the 
Corallian region is divided into five districts of very unequal size, 
wholly separated from each other. The special features of each dis- 
trict were detailed, both as regards the development, composition, 
and fauna of the several subformations therein contained, and these 
latter compared with their equivalents or representatives in the other 
districts. The old names were, as far as possible, retained; but, 
where obviously inapplicable, local names replaced them. 
In the Weymouth district fl.) one section discloses 230 feet of beds 
between the Oxford and Kimmeridge Clays, made up in ascending 
order of grits, clays, marls and oolites, gritty limestones very fossili- 
ferous towards the top, clays, and grits. Another section on the 
opposite side of the anticlinal shows the same development of the 
central limestones ; but the lower series is considerably attenuated, 
and the upper series (Supra-Coralline) shrunk from about 90 feet to 
a thin ferruginous band of only a few inches. There are hardly any 
corals, and no Coral Bag whatever; argillaceous and arenaceous 
matter, always, however, more or less mixed with lime, prepon- 
derates, but there is a rieh and varied fauna, which has strong 
affinities with some of the Corallian beds of other districts. This 
culminates in the Tr igonia -beds, which lie towards the top of the 
main limestone series ; above this the fauna inclines to Kimmeridgian, 
below to Oxfordiau types. The remarkable irregularity of the Supra- 
Coralline beds was noted, especial reference being made to the 
mineral character, fossil contents, and geological position of the 
Abbotsbury iron-ore. In the North Dorset district (II.) the thick- 
ness of the mass is much reduced, and its Constitution greatly altered. 
Corals are still very rare, but calcareous Sediment greatly pre- 
ponderates, and is made up largely of comminuted shell, loosely 
aggregated pisolites, and rubble, frequently false-bedded ; the 
arenaceous base of the Corallian series, described generally under
