 .spotted. Dorsal, caudal, anal, and ventral fins purple, the first two and the

Through the fortunate capture by its discoverer of a second e.Kanaple of 

 this beautiful longfin, I am now in a position to give a fuller and more correct 

 description than was hei'etofoi'e possible, the head of the original specimen being 

 much distorted. The jn'esent description, which supersedes the first, is, therefore, 

 taken from two examples, measuring respectively 151 and 125 mm. over all, taken 

 at Green Island, Moreton Bay, by Mr. Edwin Alfred JoUiffe, who generously 

 pi-esented them to the Queensland Museum, and after whom I have had much 

 pleasure in nanung it, in slight I'ecognitioii of his keen interest in all matters 

 relating to marine zoology. 



Our illustration is taken from the smaller example mentioned above.
