OF NEW SOUTH WALES. 375 



the anal has three spines and six rays ; the body scales are rather 

 large ; along the base of the spinous dorsal there is a sheath 

 covered with very minute scales ; the colour is nearly black ; the 

 dorsal, caudal, and anal fins are variegated with grey ; the largest 

 specimen is thirteen inches in length ; the other about nine ; 

 only seen twice in the Sydney market in September. The form 

 of the teeth obliges me to put this fish in the genus Aplodactylus, 

 but it evidently comes very near Ghiro7iemus, and I certainly 

 think that, on account of the simple lower raye of the pectorals, 

 ought to be placed in the same family ; the number of the 

 simple rays (seven) does not allow me to unite this fish with 

 the species arctidens or lopJiodon. 



Atypichthts strigatus. 

 Aty]pus strigatus, Gunth. Catal., vol. II, p. 64. 

 This fish looks very much like some species of Ghmtodon, 

 but the body is of a longer oval ; it is silvery white, with five 

 very broad longitudinal brown stripes on the sides, and on the 

 sides of the head ; fins of a bright yellow ; it does not attain 

 more than five or six inches in length ; very common at Port 

 Jackson, and usually used as bait by the fishermen.

Specimens entirely similar to the one from Swan River are 

 caught at Port Jackson ; it resembles very much Cuvier's figure 

 of Chcetodon strigatus, and I should have united it with it if it 

 had not been for the opercule, which is strongly emarginated on 

 its upper part, forming thus two points. 



The specimens are usually five inches long ; when fresh, they 

 are of a silvery- white, with five or six broad brown longitudinal 

 stripes on the sides ; the lower ones being oblique ; the base of 

 the caudal is of the same colour ; the stripes extend on the 

 head, and two of them follow the forehead ; there is also one in 

 front of the eye. 



Found in the warm season.
