This paper reviews the new taxa made available by Gray in the Griffith & Pidgeon (1833–1834) English translation of Cuvier's famous Le règne animal 1830, as well as the taxa attributed, correctly or incorrectly, to Gray in this work. We discuss various complications concerning the dating and authorship of these taxa, and some new information is provided about their type material.

Six generic names date from this work, five of them now considered valid. Sixty-five species names were made available, of which 44 are now considered valid, although some of these have not been recognized in recent literature, and one is a nomen dubium; 21 are placed in synonymy because they are junior synonyms, preoccupied homonyms, or unused senior synonyms that have been or should be suppressed.
