FISHES. MCCULLOCH. 135 



The new species is vei*y different from the only other Austra- 

 lian member of the genus, H. haswelli, mihi. 7 It has a much 

 smaller and more spinate head, and the lateral margins are 

 divided into lobes. The anal commences in advance of the second 

 dorsal instead of behind it, and the teeth are very much 

 smaller and differently arranged. 



I have much pleasure in associating the name of Mr. J 

 Douglas Ogilby with this pretty Queensland species.

 Head from tip of snout to end of opercular flap 3.35 in the 

 length to the hypural. Depth before the first dorsal 4.6, width 

 2.7, eye 4.8, snout 2.87, first dorsal spine 2.42, first ray 2.3 in the 

 head. 



Body elongate, depressed, the width much greater than the 

 depth. Under surface of anterior half flat. Snout flat, width 

 at angle of maxillary 1.23 in its length. Maxillary reaching 

 the level of the hinder nostril, 3,37 in the head, Lower jaw 

 much longer than the upper. A single large sabre-like spine at 

 the angle of the preoperculum, which is deeply grooved above 

 and below, and is longer than the orbit, being 4 in the head. 

 Three small spines on the bony stay of the cheek, the first just 

 behind the level of the anterior nostril, the second below the 

 pupil, and the last below the hinder margin of the orbit, A 

 rather strong spine on the upper anterior margin of the orbit, 

 and a series of about ten very small ones at the postero-superior 

 margin. A small nuchal spine on each side. Interorbital space 

 narrow, concave, its width less than half that of the pupil. Broad
