The next in order of proposition is Narcohatus, introduced by 

 De Blainville in 1816, and this should accordingly be adopted. 



III. 



In 1862, in a note on the classification of the " Torpedinoidfe " or 

 "Xarcaciontoidse," I proposed a new generic name for the Torpedininre, 

 or " Xarcaciontinoi " without dentiform processes round the spiracles, in 

 the following terms: 



Spiracles with deutated borders Xarcacion. 



Spiracles with smooth borders ( Torpedo occidentalis St. ) Tetronarce. 



Tetronarce should of course have been Tetranarce, the name alluding 

 to the four-sided form. Tetronarce was purely a printer's blunder. 



In 1886 Dr. G. Fritsch, in a communication on the systematic arrange- 

 ment of the species of Torpedo,^ proposed the same subdivision as the 

 preceding, calling the Narcacion of Gill Fimbriotorpedo, and the Tetra- 

 narce of Gill Gymnotorpedo. 



lY. 



In 1826 Dr. J. J. Kaup^ proposed a new genus named Narlce for the 

 Raja capensis of Gmelin, which he defined in the following terms: 



Narkc. Eaja Gmel. Torpedo Schneid. Kennz. der Gattung. Scheibe des KiJrp- 

 ers rnnd. Eiickeu gewolbt. Spritzlocher, die kurzeu Robrcn hinter deu Augeu. 

 Schwanz fleischig, kurz, mit einer EUckenflosse. 



Diese Gattuug ist nahe mic Torpedo verwandt, von welcher sie der gewijlbte 

 Eiickeu und der Mangel der einen Schwauzriickenflosse uuterscheidet. Eine Art. 

 Raja Gronoviana, Lact^p. Raja capensis, Gmel. 



As the generic name Narke was published more than a decade before 

 Astrape and was well defined, the former name (not having been previ- 

 ously used) must be revived. 



V. 



The genera of Xarcobatids were segregated by me in 1862 into three 

 subfamilies. These are well distinguished by skeletal and visceral 

 characters, as well as external ones, and are here retained. Diseopyge 

 may represent a fourth subfamily distinguished by the united ventrals. 

 The essential synonyms of the respective subfamilies and genera are 

 also given.
