100 ' ENDEAVOUR " SCIENTIFIC RESULTS. 



Pectorals angular, the outer angle somewhat rounded, 

 the inner much produced and extending back to behind the 

 dorsal spine or almost to below the middle of that fin. Dor- 

 sal spines strong, compressed, with sharp anterior edges and 

 a groove on each side, and the hinder surface broad and 

 excavate ; one-fourth to one half of the anterior spine is 

 exposed, and half or more than half of the posterior. Dorsal 

 originating far behind the axil of the pectoral, the length 

 of its base more than two-fifths of the inter-dorsal space. 

 Second dorsal about three-fourths the size of the first and 

 similar to it in form. Veritrals small, the outer angle a little 

 rounded, the posterior acute. Caudal rather broad, about 

 one-fifth the total length ; sub-caudal lobe well developed, 

 separated from the terminal lobe by a notch. 



Colour. Grey above, lighter beneath, without darker 

 markings. 



Described from three females and one male, 760-800 mm. 

 long. The example figured, a female, is selected as the 

 type. 



I associate with this species the name of my friend, the 

 late Mr. Charles T. Harrisson, who was Biologist on the 

 " Endeavour/' and who was responsible for the collection 

 and preservation of many of the more interesting fishes 

 referred to in this Report. 



Loc. Near Gabo Island, Victoria. 



Genus ACANTHIDIUM, Lowe. 



ACANTHIDIUM QUADRISPINOSUM, Sp. nOV. 



(Plate xiv., fig. 5-8.) 



Head depressed ; snout very long, more than half the 

 length of the head, with sharp edges, and rounded in front. 

 Nostrils much nearer the end of the snout than the upper 

 lip, the space separating them equal to about two-thirds 

 their distance from the end of the snout ; their inner portions 

 with free skinny borders. Mouth below the hinder portion 

 of the eye, its width less than its distance from the nostrils. 

 It is slightly arched, and has a long upper and a short lower 

 labial fold at each angle ; the upper groove is continued 

 backward almost to below the end of the spiracle. Eye 

 large, nearly three in the length of the snout ; orbit equal 

 to its distance from the nostrils, and somewhat less than the
