[The name of the compiler is not published on the title-page. Iu the usual introduction, 

 Mr. Gray states: ''The characters of the genera of Sharks and Rays, with their sy- 

 nonyms, have principally been derived from the work of Professors Miiller and Henle. 

 The specimens which were not named by thoso authors wheu engaged iu their work, or 

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

 bility of tbe compilation, however, apparently devolves on JOIIN EDWARD GRAY. 

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

 fact, translated or transcribed from Miiller and Henle's great work on the Plagiostomes, 

 entitled i-s follows: Syi-tematische Beschreibung der Plagiostomen von Dr. J. MULLER, 

 o. o. Professor der Auatomie und Phys ologie, und Director des auatomischen Theaters 

 und Museums in Berlin, uud Dr. J. 11ENLE, o. 6. Professor der A natouiie uud Director
