ORTHRAGORISCUS NASUS. 209 



NOTE XXVI. 



ORTHRAGORISCUS NASÜS RANZ. ON THE 

 DUTCH COAST 



Dr. C. L. REUVENS. 



(Plate 3). 



19 November 1896 fishermen caught in the neighbourhood 

 of Helder a large specimen of the moonfish, and brought 

 it immediately to the Zoological station, where it arri- 

 ved alive. The director , Dr. P. P. C. Hoek , addressed 

 the fish to the Leyden Museum , and we received it next 

 morning, 20 Nov., in the best, fresh condition. 



Examining the animal it proved to be Orthragoriscus 

 nasus Ranz. It agrees entirely with the specimen from 

 Callantsoog, described by Dr. van Lidth de Jeude in 

 «Notes Leyd. Mus., Vol. XIV, p. 127, pi. 5"'), though 

 the dimensions are considerably greater. 



I will give here a comparative table of the dimensions 

 of both specimens: 



Helder Callantsoog 



Distance from tip of snout to extre- 

 mity of tail 184 cM. 123 cM. 



Distance from root of dorsal fin to root 

 of anal fin, measured at their ante- 

 rior side 97 cM. 76 cM. 



Distance from root of dorsal fin to root 

 of anal fin, measured at their poste- 

 rior side 80 cM. 64 cM.
