294 ON A RARE SPECIES OF PERCfl FROM PORT JACKSON, 



(F.v.M.,) in South Australia sometimes exceeds two inches in 

 diameter, which is about four times that of E. longifolia, or our 

 common Woolly Butt, a species remarkable amongst the Eucalypts 

 of New South Wales for the size and thickness of its seed-vessel.

As this fish is apparently new to our waters, the following 

 notes may be of interest to the Society : 



The horizontal diameter of the eye is one-fourth of the length 

 of the head, and equal to its distance from the snout. The height 

 of the body is one-third of the length, exclusive of the caudal fin, 

 the length of the head is three times and two-thirds in the same. 

 Snout very short, mouth obKque ; the maxillary reaches to below 

 the anterior third of the eye. The prseoperculum is finely serrated 

 on both limbs and rounded at the angle ; the operculum has a fiat 

 spine at its upper angle, and a smaller fiat spine below it with a 

 denticulated margin. The dorsal fin is low, the third spine the 

 longest, the membranes connecting the spines and rays are clothed 

 with scales for two-thirds of their height ; the pectorals are long, 

 narrow, of twenty rays, much longer than the head, and reach to 

 the fourth dorsal ray, and first anal spine ; the anal is moderate, 

 its tip reaching to the vertical from the last dorsal ray ; the 

 ventrals are inserted just behind the vertical from the base of 

 the pectorals, and are a little longer than half their length. The 

 lateral line terminates about six or seven scales from the base of 

 the tail, the upper lobe of which is the longest. The space
