Ray Society : Annual General Meeting

THE hundred and fourth annual general meeting of the Ray Society was held on March 17. It was announced that Pennant‘s "Tour on the Continent 1765", edited by Prof. G. R. de Beer, would be published shortly as part of the issue to members for 1947, and other volumes relating to the British fauna and flora are in active preparation, including Prof. Berrill‘s work on the Tunicates, Mr. Danny‘s volume on British vice-counties, Messrs. Locket and Millidge‘s "British Spiders", the late Prof. W. M. Tatter-sail‘s monograph on the Mysidacea, and a second volume of Prof. Balfour-Browne‘s "British Water Beetles". The greatly increased cost of printing is likely seriously to hamper the activities of the Society, and an urgent appeal is made for new subscribers—both institutions and individuals. Prof. G. R. de Beer, Mr. A. C. Townsend and Dr. Errol White were re-elected president, honorary treasurer and honorary secretary respectively ; Capt. C. Diver and Dr. W. S. Bristowe Were elected vice-presidents and Dr. Malcolm Smith, Dr. John Hutchinson, Major Maxwell Knight and Dr. Ethelwynn Trewavas new members of council.

Report on the Fish and Fisheries of Lake Nyasa

MRS. RICARDO BERTRAM is a naturalist (fisheries), Miss Trewavas is a systematist (ichthyology), and Mr. John Borley is an administrator with a background of natural history, and between them they studied the fisheries in Lake Nyasa, and, in spite of many difficulties, they have followed up their eight months in the field by producing this handsome report. The report is well set out, clearly written, and illustrated with beautiful and instructive photographs. With its generous appendixes, it will be the standard work on the subject for many years to come. It has no index. Report on the Fish and Fisheries of Lake Nyasa By C. K. Ricardo Bertram H. J. H. Borley Ethelwynn Trewavas. (Published on behalf of the Government of Nyasaland.) Pp. 181+12 plates. (London: The Crown Agents for the Colonies, 1942.) 12s. 6d.

University and Educational Intelligence

LONDON.—The following degrees have recently been awarded:—D.Sc. in chemistry on H. Martin (Imperial College—Royal College of Science) for thirty-one published works on the “Elucidation of the Mechanism of the Toxic Action of Insecticides and Fungicides used for the Control of Crop Pests and Diseases”; D.Sc. in physiology on Dame Anne Louise Mcllroy (University professor of obstetrics and gynaecology at the London (R.F.H.) School of Medicine for Women) for a thesis entitled “Researches upon the Prevention and Treatment of Asphyxia in the New-born” (Med. J. and Record, Nov. and Dec. 1933); D.Sc. in zoology on Ethelwynn Trewavas (private study) for published works entitled (1) “The Hyoid and Larynx of the Anura”, (2) “Enteropneusta”, (3) “A Revision of the Cichlid Fishes of the genus Lethrinops, Regan”, (4) “Scientific Results of the Cambridge Expedition to the East African Lakes, 1930-31. II. The Cichlid Fishes”, (5) “A Contribution to the Classification of the Fishes of the order Apodes, based on the Osteology of some rare Eels”, (6) “On the Structure of two Oceanic Fishes, Cyema atrum, Gunther, and Opisthoproctus soleatus, Vaillant”, together with three conjoint subsidiary contributions.

Deep-Sea Angler Fishes

THERE still remains a large field for the A discovery of new forms of animal life in the deeper layers of the ocean water masses. There, pelagic life is not concentrated at one level, but has a vertical range of many hundreds of metres in which to roam as well as thousands of square miles horizontally. The larger animals thus tend to become comparatively sparsely distributed. To sample this deep-living population, great quantities of water must be filtered, and it is only to be expected that the recent introduction of large pelagic nets would bring a considerable extension to our knowledge. Perhaps nowhere is this better emphasised than in the study of the deep-sea angler fishes of the sub-order Ceratioidea; as a result of the examination of the collection of these fishes made on the world voyage of the Dana in 1928-30 under the late Prof. Johannes Schmidt, our knowledge has been amplified and brought up to date by Dr. C. Tate Regan and Miss Ethelwynn Trewavas. Although a systematic revision of the group was made by Dr. Tate Regan in 1926, the addition of new species and collection of new specimens has been so great that the authors have found it necessary to make a further revision. In the former report the number of species was 60 while now 158 species are recognised. Previous collections had consisted, to a considerable extent, of specimens less than one inch in length which had been assigned to those known species which they most nearly resembled; it is now shown that, among the Oneirodidae, the adult characters may be assumed at a very small size.
