The examination under the high power of the microscope of the walls of Heterodera cysts found on the roots of Agrostis stolonifera L. (Franklin 1938) showed the presence of rows of markings having the appearance of small punctations, and led to the tentative diagnosis of these cysts as H. punctata Thorne. By the kindness of Dr. Thorne the writer has been able to compare her cysts with some of Dr. Thorne's material, and has found that the surface markings have the same appearance. The writer would like here to acknowledge her indebtedness to Dr. Thorne for kindly lending his material. Cysts of several strains of H. schachtii have since been examined to find out if they also bear distinctive markings of any kind.

Cephalobus parasiticus Sandground, 1939, reported from the stomachs of monkeys, is shown to resemble the sour paste eelworm, Turbatrix rediviva, so closely as to be identical with it.

It is suggested that the monkeys probably acquired the nematodes by consuming fruit, or some other vegetable substance, on which the worms were living saprophagously; having been brought to the food by visiting flies.

It has been known for many years that the stem eelworm, Anguillulina dipsaci, can be carried in or upon the seeds of a number of different plants. Kühn (1858) originally found the parasite in the diseased seed heads and seed of the teasel or fuller's thistle. Bos (1888) discovered the worms in the flowers of the onion, Allium Cepa, and found in one case 3 per cent. of the seeds were infected. Godfrey (1924) found infestations of the parasite in the flower heads of cat's-ear, Hypochoeris radicata, and dandelion, Taraxacum officinale, and discovered in both hosts that living worms occurred within the seed coats. He also obtained diseased seedlings by sowing infected seed of both hosts. Hodson (1926) reported the occurrence of the parasite in quiescent form beneath the pales of oats harvested from fields badly affected with “tulip root” and obtained small numbers of infected seedlings by sowing such seed. The number of such cases was, however, so small that he considered their occurrence might be accidental. Robertson (1928) investigating “tulip root” in oats, found the parasite in the panicles of affected plants giving rise to abortive flowers. In a number of oat grains from distorted panicles he found small numbers of the parasite between the glumes and pales and between the pales and the kernel and was able to show that after storage for a few months the worms could be revived by soaking the grains in water. He did not pursue his studies to the extent of obtaining diseased seedlings from such infected seed. Cobb (1929) found samples of seed of red clover and lucerne, as cleaned by commercial processes, yielded the parasite in a living condition when soaked in water.

Perusal of the first volume of “Nomenclator Zoologicus” shows, on p. 927, that the generic name Cylindrogaster was first proposed by Stål in 1855 for a Dermapteran insect. As a consequence of this it becomes necessary to put forward a new generic name in place of Cylindrogaster which the writer (Goodey, 1927) gave to a saprophagous nematode obtained from a culture of rat faeces.

Eighteen species of nematodes were found to parasitise sheep in Western Australia.

Trichostrongylus rugatus and Trichostrongylus probolurus were found to be present in this State, and specimens of Ostertagia mentulata, a species new to Australian records, were found on two occasions.

Larvae of Syngamus trachea pass from the intestine to the lungs of the definitive host via the blood stream. They have been recovered from blood taken from the auricles of the heart and from the posterior vena cava.

The condition of the lungs heavily infected with larvae is described.

A condition of ‘Syngamus pneumonia’ occurs in the wild state among poults of partridges and pheasants.

A brief summary of abnormalities among Cestodes is given.

A new record of melanism in T. pisiformis is made. The pigment was deposited in the vas deferens and cirrus sac in every segment.

18 specimens of tri-radiate and 3 specimens of quadri-radiate T. pisiformis are described from dogs.

A single case of tri-radiate D. caninum is reported.

A bibliography containing records of cestode abnormalities is appended.

In a recent paper (Morgan & Wilson, 1938) the authors gave an account of a general survey of helminths in poultry in Scotland and pointed out that Heterakis gallinae was by far the most common species occurring in this host and that 82·3% of the birds examined were infected. Not only was the incidence high, but heavy infestations amounting to hundreds of worms were frequently found in these birds which had picked up the worms under natural conditions.
