inserted \\holly beneath the soft dorsal, the second spine 

 longer than the third, but shorter than the longest ray ; soft 

 anal angular. Caudal sub-truncate, the upper rays a little 

 longer than the others. Pectoral inserted below the anterior 

 dorsal spines, its fifth upper ray longest. Ventrals placed 

 well behind the pectorals, the longest rays almost reaching 

 the vent. 



Colour. — Light bro\Mi, with a darker reticulating pattern on 

 the upper half of the body. This is composed of about seven 

 undulating, longitudinal stripes which are connected with each 

 other by short cross-bars, enclosing rounded lighter spots. 

 On the head the bars are broader and darker, and they cover 

 the cheeks, opercles and snout. Basal portion of the spinous, 

 dorsal mottled with yellow, the membrane of the soft dorsal, 

 anal, and caudal blackish. Pectorals and ventrals lighter, the 

 outer rays of the latter darkened. When fresh, the general 

 colour appeared olive green, the darker reticulations enclosing 

 yellowish spots. 



Described and figured from a specimen 183 mm. long, which 

 is apparently identical with Giinther's Diagramma reticulatum. 

 A second specimen, 345 mm. long, has the same general type 

 of marking, but the fight spots enclosed by the darker reticula- 

 tion are much smaller and more numerous, as is usual in larger 

 specimens of Plectorhynchus. 



Loc. — This species was originally described from Chinese 

 specimens, but Giinther later recognised it from Cape York. 

 The example here described was taken in New South Wales 

 waters, but the exact locality has not been recorded. My 

 second larger specimen was obtained at Little Island, fifteen 

 miles north of Fremantle, Western Australia.

Eleven specimens, 180-325 mm. long, exhibit some fittle 



variation in the form of the head and the colour-marking. 



The occipital prominence characteristic of adults, and well 



shown in Ogilbj^'s figure, is not always developed in the
