Trilobostrongylus bioccai n.gen., n.sp. from cysts on the lungs of Martes pennanti pennanti (Erxleben) from Algonquin Park is distinct from other members of the Angiostrongylinae primarily on the basis of its large, trilobed bursa. In addition, the dorsal ray is long and well developed, the spicules are long and slender, the externolateral rays are large, the caudal extremity of the female is pointed, and the species is ovoviviparous. Larvae developed in Discus cronkhitei (Newcomb), Zonitoides arboreus (Say), Deroceras gracile (Rafinesque), and Physa integra Haldeman. Filaroides canadensis n.sp. from small nodules in the lungs of Lutra canadensis canadensis (Schreber) from Algonquin Park is distinguished from F. martis by its much shorter spicules, its weakly developed gubernaculum, and its longer and more slender first-stage larva which failed to develop in Physa integra. Perostrongylus Schlegel 1934 is reinstated and redefined to include ovoviviparous species, namely P. falciformis (Schlegel, 1933) Schlegel, 1934, and P. pridhami (Anderson, 1962) n.comb., which were formerly assigned to Aelurostrongylus.

Over the interval 1969–1971, carcasses of 1147 mammals taken in Ontario, Canada, were examined for guinea worm. Dracunculus lutrae n. sp., was recovered from otter Lutra canadensis (Schreber). Dracunculus insignis (Leidy 1858) Chandler 1942, was found in raccoon Procyon lotor (L.), mink (Mustela vison Schreber), and fisher (Martes pennanti (Erxleben)). Female worms identified, in the absence of males, as Dracunculus sp. were found in muskrat (Ondatra zibethicus (L.), opossum (Didelphis marsupialis L.), and short-tailed weasel (Mustela erminea L.) from Ontario and a single badger (Taxidea taxus (Schreber)) from Manitoba.Dracunculus lutrae n, sp. is distinguished from other species of Dracunculus which parasitize mammals (namely D. medinensis (Linnaeus 1758), D. insignis, and D. fuelleborni Travassos 1934), by the greater length of males, greater length of spicules and gubernaculum, presence of three pairs of preanal papillae, and the arrangement in two transverse rows of papillae immediately posterior to the anus. A brief redescription of D. insignis from raccoon and mink is given. The taxonomic status of the species of Dracunculus parasitizing mammals is briefly discussed.

Common Parasite

Within Ontario Dracunculus insignis (Leidy 1858) Chandler 1942, a common parasite of raccoon, Procyon lotor (L) (prevalence > 50%), and mink, Mustela vison Schreber (prevalence > 50%), is apparently confined to the southern part of the province. In this area D. insignis was also found in fisher, Martes pennanti (Erxleben); and Dracunculus sp. was found in short-tailed weasel, Mustela erminea (L), muskrat, Ondatra zibethicus (L), and opossum, Didelphis marsupialis (L). The distribution of D. insignis coincides with that of raccoon in Ontario, and it is suggested that raccoon may be a reservoir host for this species and that mink became incorporated into its life cycle secondarily. Dracunculus lutrae Chrichton and Beverley-Burton 1973 of the otter, Lutra canadensis (Schreber), was found across the entire province and, in most areas, the prevalence exceeded 75%. During the trapping season (October–April) larvigerous females were found in 20 (44.4%) of 45 otter infected with D. lutrae in southern Ontario, but were absent from the limbs of 132 infected otter from northern Ontario.

Skulls of 631 martens (Martes americana), 810 fishers (Martes pennanti), and 373 otters (Lutra canadensis) collected throughout Ontario were examined for frontal bone lesions possibly induced by sinus nematodes of the genus Skrjabingylus. No lesions were found in marten skulls. Lesions were present in 13.4% of otter skulls and their distribution was similar between sexes and among age-groups. Among fishers, 11.6% of skulls exhibited lesions. Frequency of lesions tended to increase with age, and adult male fishers had fewer than adult females. Lesions were characterized by discolouration, swelling, and perforation of frontal bones in descending order of frequency. Lesions were largely confined to the pars temporalis of the frontal bones with a small number also found on the pars frontalis.

It has been well known since the studies of Taschenberg (1864–1872) that the larvae of Leptohylemyia coarctata, Fall., attack wheat and rye. The damage due to this fly has been observed many times in almost all European countries, and many papers have been devoted to its life-history. Of these papers the most important are those of E. Ormerod (1882–1895), S. Rostrup (1905–1911), T. Hedlund (1906- 1907), P. Marchal (1909) and finally the recent work of Kurdjumov (1914).

Fourth Stage Larva

A description is given of the processes of copulation, formation of the egg and spermatozoon, cleavage, embryogeny and hatching in B. phlebotomum. These processes were found to be essentially similar to those in other strongyle nematodes.The anatomy of the first three larval stages is described and the observations of Conradi & Barnette (1908) and Schwartz (1924) were largely confirmed.Penetration of the skin of calves by the infective larva was observed histologically. The larvae were found to have reached the dermis within 30 min. and to have penetrated the cutaneous blood vessels within 60 min. of application to the skin. The larvae were found in the lung where the third ecdysis was in progress 10 days after penetration of the skin. A description is given of the growth of the third-stage larva in the lung, the changes which take place during the third ecdysis, and the anatomy of the fourth-stage larva.The fourth-stage larvae exsheath in the lungs and travel to the intestine. After a period of growth in which sexual differentiation takes place, the fourth ecdysis occurs and the adult parasite emerges. The time required for the attainment of maturity was found to be somewhere between 30 and 56 days after penetration of the skin.This paper was written at the Ministry of Agriculture and Fisheries Veterinary Laboratories, Wey-bridge, and the writer would like to express his gratitude to the Director, Prof. T. Dalling, also to Dr W. R. Wooldridge, chairman of the Council of the Veterinary Educational Trust for their help and encouragement. The writer's thanks are also due to Dr H. A. Baylis, Prof. R. T. Leiper and Dr E. L. Taylor for their advice and help on technical points, and to Mr R. A. O. Shonekan, African laboratory assistant, for his able co-operation.

Microplectron fuscipennis , Zett., appears to be restricted for its host material to the European species of the Tenthredinid genus Diprion , Schrank. It has been recorded from D. sertifer , Geoffr., D. pini , L., D. pallidus , Kl., and, recently, from D. polytomum , Htg. The resting stage larva within the cocoon is attacked, oviposition occurring after the host has been paralysed. The present paper is an account of part of a more extensive programme of work on Microplectron which is being undertaken in view of the promising nature of the parasite and of its introduction into Canada. The biology of the species has been dealt with by Morris and Cameron (1935) and its reactions to changes in the physical environment by the present writer (Ullyett, 1936).
