Museum by Mr Cavendish Bentinck. The small specimen obtained by the ' William 

 Scoresby' probably belongs to the same species. 



Distinguished from H. macidatus and H. lahillei chiefly by the somewhat larger head, 

 the rather broader and more deeply grooved interorbital region, the more slender 

 caudal peduncle, the smaller scales, and the shorter pectoral and pelvic fins. From 

 H. pcipillosus (Schneider), of which H. percoides (Richardson) is a synonym, from 

 Australia and New Zealand, it may be distinguished by the larger head, larger eye, 

 more numerous gill-rakers, shorter pectoral and pelvic fins, and by the different 

 coloration.

Depth of body 2| to 3 in the length, length of head 31 to 3^. Snout longer than eye, 

 diameter of which is 4 (young) to 5 in length of head and about 1 \ times the narrowest 

 part of the interorbital width. A pair of spines on the snout in front of the eyes, becoming 

 less marked with age ; granular areas in front of, above, below, and behind the eyes, and 

 on praeopercular and temporal regions, sometimes obscured by thick skin in adults; 

 only the upper part of the interorbital region rough. Skin covered with minute horny 

 tubercles in the young, becoming quite smooth in examples of 100 mm. and upwards 

 in length. A more or less distinct lateral line. Lips thick and fleshy; teeth villiform,
