and to justify the association of Limulus with the Arachnida. — A paper 
was read by Dr. Gwyn Jeffreys, F.R.S., F.Z.S., on the Mollusca procu- 
red during the cruise of H.M.S. ‚Triton‘ between the Hebrides and Faroes 
in 1882. Ten new species of Gastropoda were described, and another spe- 
cies (Fusus Sabini) was fully diagnosed. The chief interest of the paper con- 
sisted in the distinction of the Mollusca inhabiting the »warm« and »cold« 
areas of that sea-bed, in accordance with the views of Dr. Carpenter and the 
late Sir Wyville Thomson. — A communication was read from Mr. Martin 
Jacoby, containing descriptions of some new species of Beetles belonging 
to the family Galerucidae. — Prof. P. Martin Duncan, F.R.S., read a 
paper on the Madreporarian genus Phymastraea of Milne-Edwards and Jules 
Haime, and gave the description of a new species obtained on the west coast; 
of India, which he proposed to call Phymastraea irregularis. — Dr, J: S. 
Garson, F.Z.S., read a paper on the anatomy of the Pygmy Hog of Ne- 
paul (Porcula salvania of Hodgson}, as exhibited in a female specimen of this 
animal which had lately died in the Society’s Gardens. Dr. Garson came to 
the conclusion that this animal was not sufficiently different from the true 
Pigs (Sus) to warrant its generic separation. — A communication was read 
from Mr. Osbert Salvin, F.R.S., containing an account of a series of 
Birds collected by Capt. A. H. Markham, R.N., at various points of the 
western shores of the Pacific, from Esquimault on the north to the Straits of 
Magellan on the south, including some from the Galapagos Islands and from 
the island of Juan Fernandez. — Mr. E. W. White, F.Z.S., read some 
notes on the Birds of the Argentine Republic, being a supplement to two 
former papers read before the Society on the same subject. — A communi- 
cation was read from Mr. A. Boucard, C.M.Z.S., containing an account 
of a collection of Birds made in Yucatan by Mr. Gaumer. — P.L. Scla- 
ter, Secretary.

May 30th, 1883. — The following (zoological) Papers were read. 
1) Notes on a lower jaw of Palorchestes Azael. By Charles W. De 
Vis, B.A. — A fine specimen of the right ramus of the lower jaw of a 
young Palorchestes Azael, now in the Brisbane Museum was fully described 
in this paper. Reference was made to Prof. Owen’s account of an adult 
jaw of the same species (Foss. Mamm. Aust. Pl. CVI); and the relations of 
Palorchestes to Sthenurus, Macropus, Protemnodon etc., discussed as fully as 
the evidence allowed. The author regards it as a true saltigrade of the Ma- 
cropod type, closely allied in many respects to Sthenurus, though with a pre- 
molar of a quite distinct character. — 2) Synonymy of Australian and Po- 
lynesian Land and Marine Mollusca. By John Brazier, C.M.Z.S., ete. 
In this paper the author traced the synonymy of Patella aculeata Reeve; 
Natica Incei Phil., and some others, besides rectifying the identification of 
Lucina dentata Jay, which has by most authors been confounded with L. di- 
varicata Linn. — 3) On some Mesozoic Fossils, from Central Australia. By 
the Rev. J. E. Tenison- Woods, F.G.S., etc. The author describes the 
nature of the deposit from qualitative analysis and microscopic examination ; 
noticing the occurrence of various fossils too imperfect for specific identi- 
fication. The author describes also the two new species, Zrigonia mesembria, 
a clearly cretaceous form of the section »Glabrae«, and Pecten psila, which
