PLATE IV. 



Fig. 1. Elonichthys broumi (Jackson), photographic reproduction of the type of the 

 species, figured by Jackson in his first plate. In this beautifully preserved 

 specimen the rays of the dorsal and anal fins, as well as the ornamentation of 

 the scales, are particularly well shown. Natural size. Page 22. 



Fig. 2. Elonichthys browni, the dorsal fin of the above, reproduced from a photograph; 

 twice the natural size. 



Fig. 3. Elonichthys hrowni, photographic reproduction of the original of Jackson's figure 

 1, plate II. This specimen is of special interest as in it the posterior four of 

 the enlarged ridge scales in advance of the dorsal fin are preserved, as well as the 

 left ventral fin. Natural size. 



Fig. 4. Elonichthys browni, the original of Jackson's figure 5, plate I, with the ornamenta- 

 tion of the scales in good condition; from a photograph. Natural size.
