[The uaiiie of the compiler is oot published on the title-page. In the usual introduction, 

 Mr. Graj- states:— '■ The characters of the genera of Sharks aud Rays, with their sy-. 

 iDonyms. have principally been derivt-d from the work of Profiss-.>rs Miilier aud Henle. 

 Tlie s])eciuiens which were not named by those authors when eugaged in iheir work, or 

 by Dr. Andrew Smith, have been determined by Mr. Edward Gerr.ird." The responsi- 

 bility of the compilation, however, apparently devolves ou JOUN KDWaKD GRAY. 

 The diagnoses of the groups, and, for the most part, the synonymy of ihn species, are, in 

 fact, translated or transcr.bed from Miiller and Henlo's great work ou the Pla;;iostomes,
