This book is the first in a series which forms a part of the rich Soviet helminthological literature published in recent years. It deals with 197 species of nematodes belonging to suborders Spirurata and Filariata, re-examining and revising earlier descriptions and concepts related to them. A historical survey of the taxonomy of worms is given first, with keys to the various major groups and diagnoses of the nematode subclasses and orders. Even at this stage, certain new and interesting ideas are put forward. After a general account of the morphology and anatomy of each suborder, a diagnosis of each genius is given, together with an outline and drawing of its type species.

Parasitic Diseases of Wild Birds provides thorough coverage of major parasite groups affecting wild bird species. Broken into four sections covering protozoa, helminths, leeches, and arthropod parasites, this volume provides reviews of the history, disease, epizootiology, pathology, and population impacts caused by parasitic disease. Taking a unique approach that focuses on the effects of the parasites on the host, Parasitic Diseases of Wild Birds fills a unique niche in animal health literature.

For many years the Keys have provided a working tool to those within the field and laboratory needing to know "what is this worm?" They have also helped to establish a classification, using associations of characters, that gives real insight into nematode relationships across the group and their lines of evolution. This supplementary volume is designed to complement the original CIH Keys, now reprinted as one volume, with the additional convenience of reordering into superfamily. The supplement includes revised and redescribed taxa and draws attention to new taxa, to generic level, published by many authors after the original Keys were complete. It also identifies the current position of some of the older genera not included in the original Keys.
