coxae anticse basi contiguae ; mesosternum depressum, leviter ex- 

 cavatum ; sutura prima abdominis distincta ; femora dentata ; 

 unguiculi bifidi. 



A very distinct genus, well differentiated from all the forms 

 of Centrinus by the dilated sides of tlie prothorax, and bifid 

 claws. The anterior coxee diverge so as to form a continua- 

 tion of the pectoral canal. 



Enojys interruptus. 



E. breviusculus, rufo-brunneus, sat dense griseo-pubescens ; antennis 

 concoloribus ; funiciilo articulis duobus basalibus elongatis ; pro-

Oil the Proper Generic Name of the Tunny and Albicore. 

 By Theodore Gill. 



In 1817, in the first edition of the ' Rogne Animal,' Cuvier pro- 

 posed two subgenera of Scomber, which he employed, however, in a 

 generic sense : one, Thynnus, was based upon the common tunny 

 (with which were associated other and smaller si^ecies), having 

 moderate pectoral fins ; and the other, Orcynus, was based upon the

 were combined into one under the name of Thynnus. In 1861 the
