Recent Acquisitions at the Natural History Museum

AMONG recent additions to the zoological collections are specimens of Ungulate mammals from the Sxidm presented by Major P. H. G. Powell-Cotton and Miss Diana Powell-Cotton. A fine specimen of adult beaver from Norway has been purchased, and an interesting series of Crustacea from the Bering Sea and the Sea of Okhotsk, regions previously very poorly represented in the Museum collection, have been received by exchange. A specimen of a rare mollusc, Halicardia flexuosa, from the Atlantic Ocean off Cape Point, South Africa, has been presented by the director of the South African Museum, Cape Town. The Department of Geology has recently acquired, through the generosity of the Committee of the Torquay Natural History Society, more than 160 Devonian invertebrates from Devon, all of which are type or figured specimens; and has received from Mr. M. H. Donald a large collection of fossil invertebrates, formed by the late Mrs. J. Longstaff, chiefly from the Carboniferous of Great Britain, and including more than 20 figured specimens. The Mineral Department has received by gift from Prof. E. D. Mountain a specimen of boksputite, a species new to the collection; from Dr. E. S. Simpson distorted crystals of cassiterite from Pilbara goldfield; and from Mr. R. Murray-Hughes a series of rocks collected by him on the Aberdare Range, Kenya Colony, in 1933. A piece, weighing 99 gm., of the meteoric stone which fell on May 26, 1932, at Kuznetzovo, Tatarsk district, Siberia, has been acquired by exchange.

Animal Communities of an Illinois Prairie

Introduction For the purpose of ascertaining (i) the composition of the animal community of a typical high prairie, (2) any seasonal variations in its composition, and (3) its relation to the hydrosere and to secondary animal succession, quantitative collections of invertebrates were made in I925 and i926 at nine stations in central Illinois, together with observations of the several habitats.

This discordance, a difference of nearly 50 degrees, meant one of two things: either it was due to faulting or to an unconformity. Later detailed work has shown conclusively that here we have an unconformity, which was the result of crustal movements of considerable magnitude.Briefly stated, it is the writer’s conclusion, after studying the unconformity mentioned above, together with fairly large collections of fossil invertebrates from both above and below the line of contact, that we have here the evidence of a structural break of more than local importance; that the fauna found above the unconformity in beds associated . . .

The Occurrence of a Fresh-Water Medusa (Limnocnida) in Indian Streams

MR. S. P. AGHARKAR, lecturer on biology in the Elphinstone College, Bombay, who has been kind enough to undertake the collection of fresh-water invertebrates on behalf of the Indian Museum, has recently sent me several specimens of a medusa from small streams in the Western Ghats. Although they were taken at so great a distance from the west coast of India, it is important to note that these specimens were obtained from a river-system which flows across the Indian Peninsula and reaches the sea more than 500 miles away on the shores of the Bay of Bengal. Mr. Agharkar writes as follows:—

IV.—List of Thomas Say's Types of Maryland (U.S.) Tertiary Mollusca in the British Museum

To those students interested in the palæontology of Maryland, United States, it may be welcome intelligence to know that the “John Finch Collection” of Tertiary Mollusca from that State, including some of the type-specimens figured and described by Thomas Say in 1824, is in the possession of the British Museum. This fact has only recently been recognized through the examination of certain documentary evidence connected with the history of the fossil invertebrate collections contained in that institution.

The Fisheries Exhibition

THE allusion that you made to the marine invertebrates in our department led one of your scientific readers immediately to examine them. He was surprised to find them properly arranged, classified, and named, with a few exceptions. All the alcoholic specimens were looking bright and beautiful. The specimens of the marvellous Alcyonadan of British Columbia, Osteocella, Gray, or Verrillia Blakeii, as it is called by those who have sent it, are in a state of perfect preservation. They are not so well accommodated as I could wish, owing to their great length, 6 or 7 feet; still they are to be seen very distinctly, doubled up in a glass jar, 3 feet 5 inches in height, filled with strong alcohol clear as water. The fine specimen of Cryptochiton stelleri, collected and contributed by His Excellency the Marquis of Lornee, was also found by your reader to be properly exhibited in a convenient glass jar, and labelled inside and out. The large and interesting collection of marine invertebrates exhibited by the Government of the Dominion of Canada is formed of collections contributed by the Museum of McGill College, Montreal, Laval University, Quebec, and from the Nova Scotia Provincial Museum. The collection of Edible Mollusca was made by the late John R. Willis, of Halifax, N.S.

Geographical Notes

PROF. NORDENSKJÖLD in a short paper to the Paris Academy of Sciences, gives a list of the collections obtained during his recent expedition, which are to be arranged and described on his return to Stockholm. There are numerous observations on climate, magnetism, auroræ, hydrography, geology, fauna, flora, ethnography, &c. Among the collections is a very rich collection of invertebrates taken during the numerous dredgings of Dr. Stuxberg in the Glacial Ocean; to judge from these dredgings, the fauna richest in individuals, at the depth of 30 to 100 metres, is not to be found in the tropics, but only in the Glacial Ocean and Behring Strait; yet here the temperature at bottom is always 1° to 2° C. below zero. Collections of phanerogams, lichens, and algæ were made by Dr. Kjellman and Dr. Almquist; masses of bones of sub-fossil whales of the Chukchi peninsula and of Rhytina stelleri of Behring Island; a very fine collection of tertiary fossil plants from Nagasaki and Labuan; this collection is expected to afford information on the former equatorial climate and on the ancient centres of dispersion of the present floras. Cut stones, utensils, arms, dresses, &c., of Chukchis and Eskimo; the latter at present use both weapons of stone and the Remington rifle. This collection contains among other things drawings, engravings, and sculptures in ivory, which have much resemblance to the palæolithic designs of France. Lastly, there is a collection of 1,040 works in 5,000 or 6,000 volumes of Japanese books and MSS., printed or written before the opening of the country to Europeans. The Vega left Naples for Lisbon and Portsmouth on Sunday.
