rows ou tlie cheek, excluding those on the lower liuil) ol' the preopcrculum. 

 Maxilla not quite reaching the vertical of the anterior margin of the eye. 

 Freorhital more than half as w;ile as the eye, and armed with a strong spine, 

 below which are several denticulations. Hinder margin of the preoperculum 

 serrated, its angle projecting a little backward and coarsely denticulated. Oper- 

 culum armed with a single spine. A band of line teeth in front of each jaw, 

 which changes to a single row on each side; vomer and palatines toothless. 



Lateral line arched anteriorly, then running parallel with the curve of the 

 back until below the end of the dorsal fin, where it descends to the middle of 

 the cau<lal iieduncle. The scales above it are parallel with it, but are arranged 

 in oblique rows on the side of the body. There are four scales lietween the 

 latend line and the middle of the spinous dorsal. 



The fourth to the tenth dorsal spines are subequal in length, and are 

 -■ifiorter than the rays, which increase slightly in length to the seventh; the 

 margin of the fin is not excised between the spinous and soft portions, and 

 is rounded posteriorly. Anal spines increasing in lengtli backward, but the 

 third is shorter than the anterior ray. First ray of the ventral filamentous, 

 reaching beyond the vent. Caudal forked, the upper lobe produced beyond the 

 lower. 



Colour. — The general colour appears to have been l)right yellow, with violet 

 stripes between each row of scales; these are longitudinal above the lateral line 

 and oblique below it. The dorsal profile between the nape and the end of the 

 fin is dark violet. Head yellow, darker above, with broad blue stripes; two of 

 these cross the snout between the eyes, and a tliird extends from the upper lip 

 to the lower margin of the eye. and terminates in an expansion on the upper 

 part of the preoperculum; another band passes ol)liquely across the cheek to 

 the operculum, where it Ijends sharply downward and forms an acute angle. 

 Spinous dorsal with a yellow margin, followed by a pale violet submarginal 

 band, beneath which the membrane is iridescent with yellow and violet ; second 

 doi-sal and anal colourless. Pectoral with a (hirk brown streak across its base. 

 First ventral ray yellow, the rest of the fin white. Caudal yellow, with a 

 violet stripe on each lobe, the upper of whidi is separat(Hl from the outer 

 margin ; a violet border posteriorly. 



Described and figured from a specimen 172 mm. long to the end of the 

 middle caudal rays. 



This example is apparently referable to .S. temporitlls, though it differe 

 in several details from Lesson's rather crude figure quoted above. 1 have com- 

 pai-ed it with two specimens recordc^l by Macleay under the same name from 

 Port Moresby, and find if identical. The sjiecies has not hitherto been recog- 

 nised from Australian waters.

Synoininv/. — A comparison of the holotype of I. eacatua with a smaller 

 Kiiwaiian si)ecimen which is evidently /. paro)iinu!< shows them to be similar in 

 all details excciit the position of the anterior dorsal spine. This is a little 

 farther Lack in the larger example, but is not so far back as is illustrated in
