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 arrived 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, pl. 5” 1), though the dimensions are considerably greater.
