The new genus is distinguished from Hyostrongylus by the structure of the spicules, the branching of the dorsal ray, the structure of the genital cone and the arrangement of the rays of the lateral lobe of the bursa. The genera Bergheia, Hyostrongylus and Parostertagia are discussed and the present position of the four separate species named Ostertagia skrjabini is reviewed.

This is a systematic monograph of an important family of nematode worms parasitic in vertebrates. It includes thirteen subfamilies, ninety-three genera and species. They are known from all classes of vertebrates but only in one fish, a few amphibians, fewer reptiles and more birds and they seem to have reached their greatest evolution in mammals, in which they range from monotremes to man.
Two species, Haemonchus contortus and Mecistocirrus digitatus, occur in man, the former being found also in the bear, pig, several ground squirrels, camel, axis deer, elk, caribou, several American deer, buffalo, many antelopes, sheep, goats, bison and cattle. The latter species has fewer hosts, being known only from the pig, cattle and Indian buffalo. The organs usually infested are the stomach and intestine. This monograph gives the bibliography, synonymy, measurements, morphology, organs infested, geographic distribution, and a diagnostic figure of each species but unfortunately no figures.
