origin of the anal corresponds to the sixth dorsal ray ; the si)ines are 

 moderately developed : the first is less than one-half the length of the 

 second, the second stronger and rather shorter than the tliird,the third 

 less than one-half of the first and second rays, which are equal in 

 length to the longest dorsal spines; the posterior rays rapidly decrease 

 in length. Of the length of the ijectoral rays, which are di'ied and 

 shrunken, an approximate statement only can be given. The second 

 simple ray is very elongate, and appears to reach to the origin of the 

 anal ; the other rays, beneath it, also project beyond the membrane, 

 and the inferior ones become gradually shorter. The base of the 

 ventral is very remote from that of the pectoral, and faUs below the 

 ninth dorsal spine ; its length is about one-seventh of the total, and 

 the length of the spine is three-fifths of the adjacent ray. 



The scales are of moderate size, cycloid, with the fi-ee surface 

 finely granulated. 



The ground-colour is now dirty-yellowish — probably red or rose- 

 colom-ed in life. The head and body are crossed by eight black 

 bands, descending backwards in an oblique dii'ection : the fu-st is 

 nearly vertical, below the eye ; the second from the nape of the neck 

 across the shoulder to the root of the pectoral ; the tliird from the 

 membrane between the first four dorsal spines towards the root of 

 the ventral, to which, however, it does not extend. The three fol- 

 lowing bands terminate shortly below the lateral line : the fourth 

 from the upper margin of the dorsal between the sixth and tenth 

 spines ; the fifth from the margin between the last five spines ; the 

 sixth from the membrane and base between the ninth and sixteenth 

 dorsal rays ; the seventh from the membrane and base between the 

 last nine rays round the tail ; the eighth round the root of the caudal 

 fin. There do not appear to be any other spots on the fins, 



inches, lines.
