126 DESCRIPTIVE CATALOGUE OF AUSTRALIAN FISHES, 



the maxillary has its dilated portion scaly, and extends to behind 

 the middle of the eye. The upper jaw has three pairs of strong 

 teeth in front and a series of smaller ones laterally ; the lower 

 has about fifteen on each side. The dorsal fin terminates at a 

 short distance from the caudal, the posterior rays longer than the 

 anterior ; caudal rounded, rather prolonged ; pectorals two-thirds 

 of length of head ; ventrals extend beyond the origin of the anal. 

 Gill-rakers lanceolate, disposed at moderate distances, half as 

 long as the eye. Greyish-brown, with smaller and larger sub- 

 ocellated blackish-brown spots ; fins finely spotted with brown, 

 a series of larger distant spots along the basal half of the dorsal 

 and anal fins.

 Scales rather small, lateral line with a strong curve over the 

 pectoral fin. Eyes on the left side, rather close together, the 

 head very deeply excavated above the upper orbit. The blind 

 side coloured like the other.

 specimen so exactly resembling it in all its peculiarities, that I 

 am compelled to look upon it as not accidental. 



782. Teratorhombus excisiceps, n. sp., (Plate II.) 



D. 73. A. 60. L. lat. 77. 



Height of body about one-half of the total length and twice 

 the length of the head. Teeth long, strong, acute and distant. 

 The snout is very convex about the mouth, behind this there is a 

 very deep excavation, much more than semicircular ; the upper
