are, in the majority of the figures, untorn and naturally posed, while the jaws and eyes lack 

 that post-uwrtcm distortion and the inane expression commonly noticeable in pictures of fish. 

 The results presented, indicate the efficiency of the method employed, which possesses a 

 distinct advantage, as compared with ordinary lithographs, in both the matter of cost, and 

 the accurate reproduction of minute detail. In fish-photography, as practised by the author, 

 the camera is fitted vertically, in conjunction with the special form of stand described and illus- 

 trated in association with Plate XVII. 



The figures introduced below as a tail-piece to this chapter do not belong to the series 

 illustrating the fish-fauna of the Barrier Reef proper, referred to in the preceding paragraph. 

 Thej' represent two fresh-water species of high scientific interest peculiar to Queensland, referred 

 to in the fish-descriptive chapter under the respective titles of Osteoglossiini Jardinci, and 

 Ceratodtis Forstcri. Both of them, in common witii the Giant Perch, Lates calcari/cr, Plate XLIIL, 

 Fig. I, are locally associated by colonists with the name of Barramundi, that appears to be 

 applied by the natives to a variety of large fresh-water fish. The title, in its restricted sense, 

 belongs rightly only to the members of tlie genus Ostenglossiim.
