rays which equal at least a sixth of total length, while the last double ray equalt 

 a tenth. 



The anal fin commences before the vertical of the last dorsal spine and is 

 coterminal with the dorsal fin, its base equalling a seventh ( - 14) of the total 

 length. The three spines rapidly increase in length, equalling respectively 

 the first, fourth and fifteenth dorsal ones ("02.], -06, - 08) ; the produced median 

 rays nearly equal a seventh (-15) and the last a tenth ('10) of the total length. 



The caudal fin appears to have been truncated behind and rounded at its 

 angles, and forms nearly a fifth (-19; of the length. The pectorals nearly or 

 perhaps quite equal the caudal in length. The ventrals are also about equal 

 to the caudal. 



The scales are normally large, there being about twenty-five oblique rows ; 

 the anterior portion of the lateral line runs through eighteen and the posterior 

 through nine scales. There are three rows above and nine below the lateral 

 line in front, and on the caudal peduncle three above and three below. The 

 buccal scales appear to be triserial.

The color is uniformly purplish red, fading into lighter below. There is a 

 single vertical black spot under the lateral line, below the twelfth and thir- 

 teenth dorsal spines. The operculum is also black at its angle. 



The following is a table of the relative proportions of the species ; the 

 measurements in this, as in all other cases, being taken by compasses, and 

 indicating the direct dimensions without consideration of any curvature.
