The regulation of any fishery depends for its direction upon the knowledge of the biology of the fish involved. The flying fish, Hirundichthys affinis, is the main source of animal protein available to the 210,000 people living on the island of Barbados. This is only the first in a series of studies sponsored by the Barbados Government in the attempt to intelligently regulate this essential fishery. This work deals with the development of the flying fish from the freshly fertilized egg up to the young fish about 10 days old and about 15mm. in length. Methods of identification of the eggs and young fish are given in an attempt to bridge the gap between the very young fish and the adults.

Since very early times anatomists have known of the existence of the prostate gland; somewhere between the years 310 and 250 B.C. Erasistratus, a Greek anatomist of Alexandria, discovered and named the gland in the human (Mettler, 1947). However, in spite of this early start, the physiology and the biochemistry of the prostate and other male accessory sex glands were for long neglected. But in the last few years, these structures have been the subject of comprehensive investigations (Huggins, 1945; 1946-47; Mann and Lutwak-Mann, 1951) stimulated by the growing interest in the problem of fertility in domestic animals and man.

Since 1947 the Fisheries Research Board of Canada has been conducting an investigation of the marine resources of eastern Canadian arctic waters. As part of this study, a large number of benthic, pelagic and littoral marine animals have been collected, mainly during the expeditions of the M.V. 'Calanus' (Dunbar and Grainger, 1952; Grainger, 1954; Grainger and Dunbar, 1956; Grainger and Hunter, 1959). The marine amphipods taken in the years 1947-1950 in Ungava Bay have already been studied (Dunbar 1954) and one hundred and fourteen species identified. In 1956 I began the study of the marine amphipods obtained by the 'Calanus' during 1951 to 1957 in Hudson Strait, Frobisher Bay, northern Hudson Bay and Foxe Basin.

In 1878, Butschli (1878) proposed the name Amoeba blattae for a new species of rhizopod from the alimentary canal of a cockroach, Peri-planeta (then, Blatta) orientalis. This endoparasite was subsequently transferred by Leidy (1879) to his new genus, Endamoeba. A few years later, Casagrandi and Barbagallo-Rapisardi (1895, 1895a) thought, in their turn, that the parasitic amoebae should be separated generically from the free-living ones. But, unaware of the existence of the genus Endamoeba, they proposed Entamoeba as a generic name for both Amoeba blattae and for the large non-pathogenic amoeba of the human intestine, Amoeba coli Grassi (1879).

Spalanzani (1768) was the first to study regeneration in vertebrates. He discovered this phenomenon in the limbs and tails of newts and frog tadpoles. Since then and particularly during the last seventy odd years, regeneration in vertebrates has been an attractive field of research. The studies have been directed both towards discovering the presence, absence or extent of regenerative capacities in different animals as well as towards reaching an understanding of the actual processes involved.

Tessiarsuk (literally, 'Pretty Little Lake') has been known to the Eskimos of the Nain region of Northern Labrador for a number of generations as the habitat of a small wintering population of the Atlantic cod Gadus morhua. The first appearance in official records came as a result of the 'Blue Dolphin' expeditions of the 1950's: R.H. Backus in his publication 'The Fishes of Labrador' (1957) reports a visit to the lake on August 8, 1951, although he apparently did not enter with a boat and restricted his examination to the narrow entrance and the small fresh water tributary of the lower basin.

In a study of the seasonal reproduction and movements of the barren ground caribou, Rangifer tarandus groenlandicus (Linnaeus), it has been shown that cemental annuli, formed in the incisor teeth, are reliable indicators of age. The males are sexually mature at 17 to 18 months of age; the first conception in the majority of females occurs during the third and fourth breeding season after birth. Mature bulls are in breeding condition from mid-September until early December. The rutting period extends from mid-October to the first week in November, mainly from October 20 to 25. The blastocyst implants about 27 to 29 days after mating. The corpus luteum attains its maximum size and vascularity at the time of implantation; retrogressive changes commence about 2 months prepartum.

The mechanism of the formation of the molluscan shell has been the subject of controversy since the first observations were made by Reaumer in 1709 on the normal growth and regeneration of shells. There is considerable agreement on the sites of secretion of the shell materiel and the histological identity of these tissues. However, controversy centres about the mechanism by which the organic matrix of the inner layers of the shell is released into the extra-pallial space, by which it is deposited and subsequently calcified. The controversy has, of late, gained importance in that it provides excellent possibilities for the study of the organic composition of the calcifying matrices and their manner of calcification.

This study of the mysids of the Great Bras d' Or of Cape Breton Island is part of an investigation into the bionomics of the cod worm, Porrocaecum decipiens (Krabbe), conducted by the Fisheries Research Board of Canada in Cape Breton and elsewhere. This worm occurs as a larval form in several fishes and as an adult in seals (Scott, D. M., 1953, 1954). The investigation in Cape Breton was initiated by Dr. D. M. Scott in 1949 and continued until 1951 when the author took over the study in that area.

The present paper is a report on a study of the terrestrial mammals occurring on the islands in the Gulf of St. Lawrence: Newfoundland, Anticosti, the Magdalens, Cape Breton Island and Prince Edward Island. The project was primarily undertaken in an attempt to obtain first-hand, up-to-date information on the mammalian faunas of the islands, which heretofore has been scanty and often inaccurate. [...]
