11. LYTHRICHTHYS Jordan and Starks. 

 Lythrichihys Jordan and Starks, new genus (eulabes). 



This g-enus differs from Setarehes chiefly in having- the interor])it{il 

 concave, the head more strong-ly armed with spines, the next to the 

 upper preopercle spine (which in Setar'cJieK is the largest one) scarcely 

 developed, with one less dorsal spine, and the last spine not longer 

 than the one preceding it. The notch l)etween dorsals is very deep, 

 almost separating them. 



Small species of the sea bottom in rather deep water. 



(It'^po?', gore, from the red color; ix^vg, lish.)

highest at first dorsal spines, and the ventral outline from isthmus to 

 anal straight. 



Head large, wider than body. Mouth little oblique, the tip of pre- 

 maxillary on a level with lower margin of orbit; maxillary extending 

 to below posterior orbital margin. Lower jaw slightly projecting 

 and with a small knob at symphysis, its tip fitting into a I'ostral notch. 

 Teeth in narrow bands on jaws, vomer, and palatines. Interorbital 

 space concave; at its middle a pair of interorbital ridges with rather a 

 wide channel between. Nasal and preocular spines small, but rather 

 sharp; superocular and postocular spines smaller and blunt, repre- 

 sented by notches in the superorbital ridge ; parietal ridges moderately 

 high and sharp, ending in rather ])lunt, small spines. Preopercle with 

 5 spines, the uppermost the longest, long and sharp, projecting beyond
