The lodgepole needle miner, Recurvaria milleri Busck, was discovered in 1903 in the Yosemite National Park, California, and was described as a new species by Busck (1914). The infestation has persisted in that area, with irregular periods of abundance and scarcity. The latest heavy infestation was reported (G. R. Struble, in litt.) to have started in 1947, and has continued to intensify. The history of the outbreak to 1919 was reported by Patterson (1921).In 1942 a second important infestation was reported in the Banff National Park, Alberta. Details concerning the area of infestation and life-history notes were given by Hopping (1946). This infestation has continued to spread and has reached Yoho, Kootenay, and Revelstoke National parks.

Material collected in Loch Tannoch was allowed to macerate in a chemical nutrient. A rich crop of Euglena gracilis as well as other infusoria resulted. Eight months later, when the Euglena had encysted, many amoebae were found at the bottom of the receptacle. They constitute a new species, here named Amoeba hugonis. An average adult specimen, when extended, measures about 104x52·2µ. The nucleus consists of a central karyosome lying in the nuclear sap, separated from the cytoplasm by a wellmarked nuclear membrane. Between the latter and the karyosome is situated an achromatic ‘collar’ with chromatin particles embedded in it. Fission is described, but a study of mitosis has been deferred. The life-history of this small amoeba is very similar to that of the large A. proteus, &c. The cycle occupies two months. Chromidia begin to appear in the cytoplasm of the early adult. They give rise to spores, out of which amoebulae hatch.

Allosaurus is one of the best known theropod dinosaurs from the Jurassic and a crucial taxon in phylogenetic analyses. On the basis of an in-depth, firsthand study of the bulk of Allosaurus specimens housed in North American institutions, we describe here a new theropod dinosaur from the Upper Jurassic Morrison Formation of Western North America, Allosaurus jimmadseni sp. nov., based upon a remarkably complete articulated skeleton and skull and a second specimen with an articulated skull and associated skeleton. The present study also assigns several other specimens to this new species, Allosaurus jimmadseni, which is characterized by a number of autapomorphies present on the dermal skull roof and additional characters present in the postcrania. In particular, whereas the ventral margin of the jugal of Allosaurus fragilis has pronounced sigmoidal convexity, the ventral margin is virtually straight in Allosaurus jimmadseni. The paired nasals of Allosaurus jimmadseni possess bilateral, blade-like crests along the lateral margin, forming a pronounced nasolacrimal crest that is absent in Allosaurus fragilis.

A new species, Pholis clemensi, referred to the family Pholidae, is named and described from 12 specimens taken in southern British Columbia waters and the Strait of Juan de Fuca. Pholis clemensi is compared with other members of the genus, and a key is given to the North American species.

Records are given of two species and a variety new to western Canada and notes on three other species already known from the region. A new species, Aricidea lopezi, and four species new to western North America, are described from the neighbourhood of Friday Harbour, Washington.

A half a century ago, R. T. Leiper described a new species belonging to the genus Fasciola from specimens which he collected from hippopotami at the Murchison Falls, on the Victoria Nile in Uganda, in the summer of 1907. This species, Fasciola nyanzae, was found in the bile ducts of the liver, and in most instances the specimens were somewhat macerated owing to the length of time that had elapsed before the animal could be recovered from the water. Nevertheless, the characteristic shape of these liver flukes and the restriction of the branched testes to the anterior third of the body made it possible to recognise them as being different from all other species of the genus known at that time.

During a visit to Professor Fernald, in Amherst, Mass., last spring, he showed me a Nepticula, bred from Apple, which he had described in manuscript as a new species, but which he afterwards had suspected to be Micropteryx pomivorella, Packard.From reading the description and life-history of packard's species, I felt sure that it was a Nepticula and presumably the same as Professor Fernald's species, and a week after, while studying the collection in the Agassiz Museum, Cambridge, I obtained definite proof that we were right.

AbstractHybomitra enigmatica n. sp., previously confused with Hybomitra sonomensis (O.S.), is described in larval, pupal, and adult stages and compared with the latter species and with H. phaenops (O.S.). Hybomitra philipi Stone is synonymized with H. sonomensis. The distribution of these species in western North America is given.

The ‘clover’ mite, Bryobia praetiosa Koch, has long been known to be a complex of closely related species or biological races differing greatly in host range, life-history, and habits. Morgan and Anderson (1957) reviewed the problem and described the form occurring on fruit trees in British Columbia as a new species, B. arborea, to be known as the brown mite, and these authors (Anderson and Morgan, 1958) also published a detailed study of the life-histories and habits of this species and of the true clover mite, B. praetiosa. Although the presence of Bryobia mites on fruit trees in Eastern North America, including Ontario, has long been recognized, they have seldom received more than casual mention and no extensive study of their biology in this area appears to have been undertaken. The species has little economic importance in Ontario (Putman and Herne, 1959).
