The Twenty-first Volume of the Naturalist's Library, and tenth of

the Ornithological department, is devoted to the Fly- catchers, or Museicapido : which family has been most scienti- fically treated of by Mr. SWAINSON. The minutely accurate descriptions of the various birds forming this division, are illus- trated by sharp and distinct engravings, from drawings by the author. The character of each bird is marked with the vividness of life ; and the colouring, if not pictorirally beautiful, is correct in the main. An interesting memoir of HALLER is prefixed.
