The Root Knot disease of tomatoes and cucumbers, caused by the attacks of Heterodera radicicola Müll., is of widespread occurrence and under certain conditions, notably in the presence of fungi, may cause serious losses. Under some conditions considerable infestation may be present and yet produce no apparent ill-effects on the plants.

Experiments having indicated that sodium cyanide was beneficial in reducing the amount of eelworm infestation and pot trials having suggested that calcium cyanide might also prove effective, trials with calcium cyanide were carried out at various centres in 1926 and 1927.

En 1927 Journal of Helminthology a publié une note de Goodey sur Cylindrogaster coprophaga gen. et sp. nov., provenant d'une culture des excréments de rat (Rattus norvegicus). La note donne une description détaillée de la nouvelle espèce, accompagnée d'excéllentes figures.

The species of the Nematode genus Strongyloides are of considerable interest to helminthologists and extensive studies on the biology of their life-history have been carried out by various workers. Their chief interest lies in the fact that the parasitic stage consists of hermaphroditic forms only, while in the free-living stage there may be a differentiation into males and females before reaching the infective stage. This alternation in the life-cycle is also exhibited by the allied genus Rhabdias, with the exception that, according to Railliet (1899) and Goodey (1922), certain species from the snake do not appear to have this differentiation in the free-living stage.

In October, 1927, a rusty tiger cat, Felis planiceps, died at the Zoological Gardens, London, three weeks after imporation from the Malay States. An examination of the intestinal tract and of certain portions of the connective tissue revealed the presence of at least a dozen different species of helminths, embracing many diverse groups of worms. In the connective tissue, in addition, were a number of small oval cysts, somewhat resembling a trichina cyst in outline, but much larger in size and with a totally different structure. Fat globules were seen at the poles. It was not found possible to identify them but it is possible that they were parasitic in origin.

It has been shown that turkeys (Ransom, 1921, and Ortlepp, 1923) and starlings (Lewis, 1925 and 1926) play an important rôle in the distribution of gapes disease.

The following description of a new species of the genus Oswaldocruzia is based on the examination of a considerable number of specimens collected from the intestines of 80 newts caught at Aberystwyth. They were found to be equally common in the Smooth Newt (Molge vulgaris Linn.) and the Palmate Newt (Molge palmata Dum. and Bibr.).

The occurrence of Bilharzia infection in Cyprus was first recorded by Dr. George A. Williamson in a paper entitled “Bilharzia hæmatobia in Cyprus,” published in the British Medical Journal of 27th September, 1902.
