The material on which the following description is based consists of a single pair of male and female worms obtained from under the gizzard lining of a Burmeese Pea-fowl (Pavo muticus). Although the material was so limited, the parasites are of sufficient interest to warrant their description, especially as they show characters which lead one to the conclusion that they represent a hitherto unknown species; also it is a species very closely related to A. (Cheilospirura) hamulosus, a parasite of chickens.

The Failure Of the potato crop On some fields in South Lincolnshire has been noted for several years. The stunted growth of the plant, together with the wilting and yellowing of the foliage, usually associated with root trouble, were the symptoms observed, while the yield suffered greatly owing to the small size of the tubers formed. In a few instances the crop over the whole field was so poor that the yield hardly paid for the seed planted; others shewed bad patches which seemed to increase in size year after year.

Forty years ago Schøyen (1885) gave an account of a serious disease of barley occurring in the vicinity of Lorn in Norway, which was associated with the formation of galls on the roots of the plants. The galls were found to contain eelworms which had without doubt caused their production and the symptoms of disease also. Schøyen named the worm Tylenchus hordei n.sp. Similar galls had been found at about the same time by Eriksson (1885) on diseased barley at Pajala in northern Sweden, but he had ascribed their formation to the nematode Heterodera radicicola; Schøyen discussed this and gave reasons for thinking it an erroneous view. Closely similar galls had been found previously on the roots of Sea Lyme Grass, Elymus arenarius, by Warming (1877) in Sjaelland, Denmark, and by Trail (1881) at Aberdeen, Scotland. The former had considered that they were caused by Heterodera radicicola, whilst the latter thought they were due to a nematode belonging to the genus Tylenchus, though he was not positive on this as he only saw female worms.

The following note is based on a sample of Filariae collected by Dr. W. Stefanski (University of Warsaw) from the trachea of a Black Stork shot in the neighbourhood of Warsaw and generously placed by him at my disposal.

Since Blanc created the genus Streptopharagus in 1912 for the reception of a nematode parasite from the stomach of Macacus cynomolgus (India ?) which he named S. armatus, three papers have appeared from different sources, each of which deals with what its author took to be examples of S. armatus Blanc. The first of these papers is by Vevers (1922), in which he records and figures some specimens obtained from Macacus nemestrinus (India). The second is by Baylis (1923), describing and figuring specimens obtained from Papio langheldi (Tanganyika Territory). The third is by Mönnig (1924), in which specimens obtained from Papio porcarius and Cercopithecus pygerythrus (Transvaal) are described and figured.
