3. " On a Fossil Bird and a Fossil Cetacean from New Zealand." By Thomas 
H. Huxley, F.R.S., Sec. G.S., Prof of Natural History, Government School of 
Mines. 
These remains were, the right tarso-nietatarsal bone of a member of the Pengtiin 
family, allied to Eudyptes, but indicating a bird of nuich huger size than any 
living sj)ecies of that genus, larger indeed than even the largest Aptenodytes, and 
to which the name of Palmudypies aniarcticus was given, — and the left humeras 
of a small cetacean, more nearly resembling that of the common Porpoise than 
that of any other member of tlie order (Balama, jBalieuopiera, Mumdon, Ddphinus, 
Orca, Hyperoodon) with which the author had been able to compare it. Never- 
theless, as there are very marked differences between the fossil humerus and that 
of Phoccena, Prof Huxley named the species Phocwnopsis MantelU. Mr. W. 
Mantell, F.G.S., to whom the author was indebted for the opportunity of exam- 
ining these bones, stated that the beds whence they were obtained were certainly 
of Tertiary age, and of much earlier date than the epoch of the Dinornis, which 
he considered to liave been contemi)oraneous with man. The Palceudyptes was 
from an older bed than the Phocmnopsis. 
Prof. Huxley drew attention to the remarkable fact tliat a genus so closely 
allied to the Penguins which now inhabit New Zealand, and are entirely confined 
to the Southern Hemisphere, should have existed at so remote an epoch in the 
same locality. 
4. " On the Denual Armour of Crocodilas Hastingsice." By Thomas H. 
Huxley, F.R.S., Sec. G.S., Prof, of Natural History, Government School of 
Mines. 
The author, after briefly mentioning the very complete armour of articulated 
dorsal and ventral scutes which he had recently discovered (and described before 
the Linn^an Society) in two of the tlrree living genera of AUigatoridce, viz. Caiman 
and Jacare, showed that similar scutes are foimd associated with the remains of 
Crocodilus Hastinijsia, a very fine skull and some scutes of which reptile from 
Hordwell, kindly lent to Prof Huxley by Mr. S. Laing, F.G.S., were exhibited. 
With respect to the suggestion of Prof. Owen, that the Alligator Eanioniensis 
might possibly be a variety of Crocodilus Hastingsiw, the author stated that he 
had observed in several specimens of the recent Crocodilus palustris, which by its 
straight premaxillo-maxillary suture and the general form of its skull most nearly 
approaches C. Hastingsiw, a tendency to assume the alligator character of a pit, 
instead of a groove, for the reception of the mandibular canine. Sometimes there 
is a pit on one side and a gioove on the other, and sometimes incomplete pits on 
both sides in this Crocodile. Crocodilus Hastingsiae still mure nearly approaches 
the A lligatoridce in the number of its teeth and in the characters of the dermal 
armour now described, so that the probability of its occasionally assuming the 
Alligatorian dental pits on both sides is gi'eatly increased.

■ 1. " On the Subdivisions of the Inferior Oolite in the South of England, com- 
pared with the Equivalent beds of the same formation on the Yorkshire Coast," 
by Thomas Wright, M.D., F.R.S.E. (Communicated by T. H. Huxley, Esq., 
Sec. G.S.) AVith a Note on Dundry Hill, by R. Etheridge, Esq., F.G.S. 
The author fii\st remarked that, since the publication of his memou- " On the 
so-called Sands of the Inferior Oolite" in the Society's Journal (vol. xii. p. 292), 
some geologists, both in England and on the Continent, had taken the Liassic 
character of these sands into consideration, and thatOppel, Hebert, and Dewalque 
had agreed with the author on pateontological grounds ; whilst in England Mr. E. 
Hull (of the Geological Survey) had also adopted his views. On the other hand, 
Mr. Lycett and Prof Buckman in theu- recent memoirs still regard these sands as 
distinct from the Upper Lias. 
Dr. Wright then described the beds at Bluewick, on the Yorkshire coast, which 
he regards as the equivalents of the " Cephalopoda-bed " or " Jurensis-bed :"
