Ashort description of the forms in many of the Families, and of the most typical or important of the innumerable species included in the large Passerine order. Prefixed to each group is a brief summary of the Structure and Habits. It is rarely complete, more so than any book of its class published, and the descriptions, though brief, are clear and, whenever necessary, illustrated by drawings made specially for this work. The Scheme of Classification is of great value to the Student.
