Haplochilus fasciolatus 



Eaplochilus fasciolatus Gtli., 1866, Cat., VI, 358; Sauv., 1880, Nouv. ArcL. Mus., Ill (2), 23; 

 Rocheb., 1883, Poiss. Seaeg., 139. 



D. 11; A. 18; V. 6-7; LI. 28; Ltr. 9-10. 



Depth one fourth of the length to the base of the caudal. Head rather 

 elongate, little more than depth of body, depressed anteriorly. Snout longer 

 than eye ; lower jaw little longer than upper. Eye somewhat more than 

 one fourth of the head, half of the interorbital width. Dorsal origin mid- 

 way from eye to end of caudal, opposite the seventeenth scale of the lat- 

 eral line, rather before the middle of the anal. Pectoral reaching beyond 

 root of ventral ; latter reaching vent. 



Brownish, each scale with a red spot at the base. Lower parts of sides 

 of the abdomen and tail with eight or nine oblique narrow brownish-black 

 streaks, descending from the middle of the side forward. Vertical fins with 

 purple spots, dorsal and anal with a light basal band. Reaching three inches

Depth 6ve and two thirds to five and one fifth times, and head three and 

 two fifths times in the length from snout to base of caudal. Head and for- 

 ward portion of body depressed, elongate. Crown flat, lower jaw prominent. 

 Eye little more than four times, and forehead twice in the length of the 

 head. Dorsal origin near three fourths of the distance from snout to caudal 

 base, or midway from the occiput to the same point, above or a little behind 

 the middle of the anal. The original description and the figure do not 

 agree as to position of fins. Pectoral reaching above base of ventral ; latter 

 above origin of anal. Caudal rounded, little longer than the head. 



One of the types had twelve to thirteen narrow bands of brown descend- 

 ing obliquely forward across the flank, a longitudinal band a little above the 

 middle of the flank from the eye to the caudal, and dorsal, anal, and caudal 

 marked with brownish. Two others lacked the transverse bands, but had the
