of head 1.57 in its length; eye 3.50; snout 4.; interorbital space 2.32; 

 first dorsal spine 2.25; first dorsal ray 1.68; third anal spine 2.47; 

 first dorsal ray 1.64; least depth of caudal peduncle 2.; thirty-three 

 scales in a lateral series from gill-opening above to caudal base ; 

 eleven scales counted from the vent upward and backward to soft 

 dorsal ; nineteen predorsal scales. 



Body compressed, the upper profile weakly curved, gradually de- 

 scending anteriorly, the curvature of the lower profile stronger than 

 the former; head subconic ; interorbital space convex; snout rather 

 short, convex, with a somewhat sharp edge ; eye anterior, moderate ; 

 adipose eyelid thin, not covering the iris, the posterior lid broader 

 than the anterior; mouth subinferior, slightly oblique, its angle reach- 

 ing to a vertical through the posterior nostril ; upper lip situated 

 obliquely at the lower edge of the snout, rather thin; both jaws with 

 no teeth, edge of the lower thin and sharp ; mandibular angle obtuse ; 

 the cleft of the mouth two and one-half times as broad as deep; 

 extremity of the maxillary entirely hidden by the pre-orbital, inferior 

 edge of the latter denticulated; isthmus remarkably narrow, distinct 

 only at the middle of the lower jaw; nostrils separated, the posterior 

 larger than the anterior, slit-like, situated in front of eye above. 



Scales cycloid, outer margin rounded, with a shallow longitudinal 

 groove ; those on the top of head larger and irregular, not extending 

 to the tip of snout; a sharply pointed scaly flap along the base of 

 spinous dorsal, extending backward beyond the base of the fin; 

 pectoral and ventral with a scaly flap;. a broad scaly flap between the 

 ventral bases; soft dorsal, anal, and caudal covered with small scales. 



Origin of the spinous. dorsal midway between the tip of snout and 

 caudal base, first and second spines subequal in length ; soft dorsal 

 inserted midway between origin of spinous dorsal and the base of 

 caudal ; origin of the anal in advance of that of the soft dorsal, root 

 of the fourth ray corresponds to the origin of the latter; pectoral 

 nearly as long as the head, reaching to the origin of spinous dorsal ; 

 ventral inserted below the middle of pectoral, reaching more than half 

 the distance to the vent; caudal forked, tip of each lobe sharply 

 pointed. 



Color in alcohol bluish gray above and shining silvery below, with 

 no stripes ; a black marking at the root of pectoral ; dorsals and 

 caudal dusky, the rest of the fins whitish.
