"ENDEAVOUR " 



SCIENTIFIC RESULTS. 



sented by seven specimens, the spines on the infraorbital ridge 

 are very strong and overhang the cheek below them. The 

 fii'st dorsal, pectoral, and ventral fins, as well as the under 

 surface, are much darker than in the others, and the pectoral 

 always has a light oval spot on its upper half. This form agrees 

 well with Bleeker's figure as regards the armature of the head, 

 but not in the colour. The second form only differs in having 

 the spines on the suborbital ridge smaller, and the colouration of 

 the fins lighter ; the light patch on the pectorals is also 

 absent. It is represented by the remaining twenty-five specimens, 

 which agree perfectly with an example from Dr. Day's collec- 

 tion in the Australian Museum, from Madras. 



Loc. All the " Endeavour " specimens were trawled seven 

 to twenty miles off Bowen, Queensland, in 15-35 fathoms, on a 

 muddy bottom ; August 2 and 3, 1910.
