'I'lio species is iindoiibledly ilistind rnini its Aliaiitie reprosentiitive .1. rir- 

 oinictiK, altlioiii^h some of the chanictors wiiicii have been relied upon to distinguish 

 the two are of no value. 'riiiiP, the gill-niker.s art; alike in holii and the eye does 

 not ditler in size. Tlie second anal spine is varia!)le in i)oth; in (<t;niiUas, its tip 

 usually fails to reach the tip of the soft rays, in vinjiuicus it usually reaches beyond 

 their lifts. 



The most striking difference is in the color, as has been siifTiciently described 

 by previous authors. In addition, we note that the fins in oiri/'uiicn^ are more densely 

 scaled, this being especially well marked with the [tectorals. Tlie anterior portion of 

 the spinous dorsal dillers widely in contour: in vmjinicus, the lliird spine is longest, 

 the second live-sixths or more than five-sixths the length of the fonrlh; \i\ /u nia(ti>^, 

 the fourth spine is usually the longest, the second very short, not more than four- 

 sevenths the length of the fourth. Our material is not sufTieient to enable us to deter- 

 mine the limits of variation in the relative lengths of the dorsal spines. The pectoral 

 seems to be slightly longer in Ueniatufi, and the preorbital a little narrower, but these 

 differences are unimportant.
