(Plate 8). 



On the 13th of Dec, 1889 a great Sun-fish was washed 

 ashore at Araeland. Through kind intervention of the mayor 

 of the island , D. W. J. baron van Heeckeren , the gigantic 

 fish was sent up to the Leyden Museum, where it arrived 

 a few days afterwards in a satisfactory state. As far as I 

 know of, it is one of the largest specimens of Orthra- 

 goriscus. The dimensions are as follows: 



Distance from the tip of the mouth to the ex- 

 tremity of the tail M. 2.23 



Distance from the root of the dorsal fin to the 

 root of the anal fin , measured at the anterior 

 part of the fins M. 1.40 



Distance from the root of the dorsal fin to the 

 root of the anal fin , measured at the posterior 

 part of the fins M. 1.12 



Distance from the top of the dorsal fin to the top 



of the anal fin M. 2.80 



Distance from the tip of the mouth to the ante- 

 rior part of the root of the dorsal fin . . . M. 1.45 



Distance from the tip of the mouth to the ante- 

 rior part of the root of the anal fin. . . . M. 1.53 



Breadth of the dorsal fin measured at the root . M. 0.42
