D. 10/13. A. 3/8. L. lat. 50.. Coec. pylor 5. 



The height of the body is 3 J in the total length, and the length 

 of the head 3^ ; the diameter of the eye one fourth of the length 

 of the head. Jaws equal, the upper maxillary bone reaching 

 nearly to below the middle of the eye. Prseoperculum indistinctly 

 notched, the denticulations becoming gradually stronger at the 

 angle ; no knob on the interoperculum. Caudal fin truncated, 

 pectorals not reaching to the anal ; the third, fourth, and fifth 

 dorsal spines, and the second and third anal spines, nearly ecptal 

 in length and strength. 



Yellowish olive, with oblicpie streaks above the lateral line, and 

 with longitudinal ones beneath ; a black lateral blotch on scales of 

 the 22nd to 30th transvere lines. 



Port Denison. (Klunzinger.) 



Species 68. Glaucosoma scapular e. Macleay. 



Several fine specimens of this Fish have been captured during 

 the last few months. It is known to some of the fishermen as the 

 " Pearl Perch," and is said to be a most excellent food fish.

 This species differs from A. urotcenia of Bleeker in the lower 

 and weaker second dorsal spine, in the number of dorsal and anal 

 rays, in the development of the lateral line and in the colour. 

 The height of the body is 3 J, and length of head 3 J in the total 

 length as in A. urotcemia. From A. agassizi Gunth. this species 

 is distinguished by its lower 2nd dorsal spine, which however is 

 higher than the 3rd anal spine, and by the armature of the 

 prfeorbital which is less distinctly toothed on the margin. There 

 is no trace of a spine above the orbital ; the ventral fin does not 

 nearly reach to the anal ; the fins are hyaline, slightly spotted with 

 black ; the silvery longitudinal band is not very distinct, and there 

 seems to be another above it on the 3rd row of scales. Lateral 

 line ill defined or none.
