03D987B81469221123B2FBFD0C686E29.taxon	discussion	Remarks. Examination of the present 18 Neobythites specimens showed three different ocellus-patterns: one specimen with one ocellus in the dorsal and none in the anal fin (= N. monocellatus), 12 specimens with two ocelli in the dorsal fin (= the holotype of N. ocellatus caught at 9 ° 5 ’ S, 34 ° 50 ’ W) and five specimens with 3 – 5 ocelli in the dorsal and 2 – 4 in the anal fin (= the 308 specimens of N. ocellatus caught in the Caribbean Sea and further north [see Nielsen 1999, fig. 10]). This indicates that the typical N. ocellatus specimens are restricted to the continental slope off mid-Brazil and that the five specimens with more ocelli are similar to the 308 more northerly caught specimens. A manuscript dealing with the West Atlantic ocellus-bearing Neobythites species is under preparation.	en	Mincarone, Michael M., Nielsen, Jørgen G., Costa, Paulo A.
