and the middle of the unal fin. Tlie fifth liand originates at tlm 

 postei'ior dorsal spines and proceeds to the posterior anal rays, 

 the last band runs nearly parallel to the margin of the dorsal rays 

 and on to the caudal peduncle, the four posterior bands extend 

 on to the scaly portion of the dorsal and anal fins. 



Log. — Two specimens, taken at Houtman's Abrolhos, the 

 larger measuring 152 nun. in length.

Length of head 3-7 ; of caudal fin 5-2 ; height of body 1-5 in 

 the total length. Diameter of eye 3-0, and length of snout 3-5 

 in that of the head. Interocular space convex, equal to the 

 diameter of the eye. Preopeiculum smooth, body ovate, strongly 

 compressed ; the upper profile rounded, the lower convex. The 

 fifth dorsal spine is the highest, its length twice the diameter of 

 the eye ; from this point the fin falls gradually away to an 

 obtuse angle at about the middle of the rayed portion. The 

 second anal spine is longest, its length being one-half that of the 

 head ; this fin is evenly rounded ; the ventral spine is 1 "6 in the 

 length of the head, and the longest pectoral ray 1 "3 in the same. 



Tlie scales are in regular series, not in contrary directions, 

 those of the middle of the sides larger than the others ; the 

 lateral line forms an even arch, lower than the dorsal pi'ofile and 

 tei^minates in advance of the posterior insertion of the dorsal fin. 



CdIoiivs. — Ground colour yellow or pale brown, snout darker, 

 the dark ocular band is complete above and is a little narrower 

 than the eye, above the orbit it is bordered before and behind 

 with a light band, below it extends to the margin of the 

 subopercle. The body bears, on its upper half, four very narrow 

 dark vertical bars slightly inclined forward below, they pass 

 downwards from the bases of the fourth, sixth, eighth and tenth 

 dorsal spines respectively. The dorsal fin is narrowly edged with 

 black ; following the angle, the colour becomes submarginal, 

 the extremit\- of the rays being white. ^V l)lack white-edged
