rays black to near their base, margins of the fin black, the lOAver marginal 

 black, wider and more conspicuous and connected with the black of the 

 middle caudal rays by a short black bar across the base of the loAver lobe. 



This species, evidently very closely related to fasciatus, is readily 

 distinguished by the peculiar color of the caudal.

 8 cr 9-44 to 48-7 or 8 (7 or 8-38 to 44-6 or 7 in I'meaimnctatus) . 



Very similar 1o luieaptinctatiis, a little more slender, the scales smaller, 

 the lateral spots faint tending to run together to form longitudinal lines.

Head 4 ; depth usually 5.5, rarely 4.5. D. 12 A. 9 ; scales 4-37-3.5. Eye 

 equals snout, 3.5 in head, less than interorbital. 



Sub-cylindrical, elongate. Preventral area ilattish, with a median 

 series of al)out twenty scales ; predorsal area rounded with a median 

 series of 11 or 12 scales; skull smooth; no fontanels, the two frontals and 

 the two parietals interlacing occipital crest decurrent, not superficially 

 evident; second suborbital covering entire cheek; mouth small, distinctly 

 inferior as in other members of the genus ; four broad graduate, straight 

 edged or rounded edged teeth in each premaxillary, each tooth with 11-ir) 

 notches; mandible without a])i)arent teeth; maxillary with a single small 

 dentate tooth. Gill rakers short slender, about fifteen in the lower arch. 



Origin of dorsal in advance of the middle of the body, usually equidis- 

 tant from tip of snout and end of adipose, its height about 4.5 in the 

 length: adipose well developed; caudal lobes four iii the length; anal six 

 in the length ; ventrals under posterior part of dorsal, not nearly reaching 

 anal, pectorals not reaching ventrals by about four sc-ales. 



Lateral line straight, scales everywhere regularly arranged; scales of 

 sides with as mai?y as five more or less divergent radials ;. Axillary scale 

 well developed, caudal and anal naked. 



A moniliform band from the eye along llie lateral line and onto but 

 usually not to the ond of the middle caudal rays; area below the band 

 white ; a light stf ipe above the band ; back dark, with the margins; of the 

 dark area and eight streaks from margin to margin darker ; base of caudal 

 with a dark spot < r streak on each lobe.
