eral line. Teeth in narrow bands in 2 series on the sides of the 

 mandibles. Canines strong. Villiform teeth also on palatine bones 

 and vomer. Brauchiostegals 7. Pseudobranchige present. Max- 

 illary reaching past vertical of posterior of eye, lower jaw project- 

 ing. Border of preopercle rounded and serrate, the serrae slightly 

 larger at angle. Gill-rakers short, 13 on lower arm, with villiform 

 teeth. Fins: Caudal rounded, its length about 2 into head. Soft 

 anal slightly longer than soft dorsal. Third anal spine the longest, 

 2.50 into head. Fifth dorsal spine the longest, 2.66 into head. 

 Pectorals rounded, 1.50 into head, their base about equal to orbit. 

 Ventrals not reaching to anus. Color in spirits: Brownish, with 

 mottlings and narrow lighter more or less hexagonal lines, white 

 below, the body with about six indistinct slightly oblique bands 

 about as wide as interspaces. The dorsal parts of these bands are 

 very black and distinct, less distinct on sides; the first is on the 

 shoulders, second from 2-5 dorsal spine, third from 7-10 dorsal 

 spine, fourth from 2-6 dorsal ray, fifth from 12-14 dorsal, and the 

 sixth forms a black saddle on caudal peduncle. i\ll of these bands 

 extend a little obliquely down to the ventral surface of body. The 

 thorax has 9 round brown spots half as large as eye. The caudal 

 is brown with small white spots and a narrow w^hite margin. The

 interorbital i.33intoeye; D. xi 16; A. iii 8; V. i 5; P. 16. Scales 

 small ctenoid, about 108 in lateral line. Upper two-thirds of hind

 one the largest, its length about 2 into orbit. Pins: The caudal is 

 rounded, its length about 2 into head. Pecftorals rounded, their
