Relations of the Fish-fauna of St. Helena. 



There are 33 species in my collection, while Melliss in his 

 book, published in 1875, mentions 68. Of those which I obtained 

 the following are peculiar to the island : — 



Congromurcena mellissii. 

 Ophichthys regius. 

 Leirus moselii. 

 Pimelepterus gallveii. 



Ghaztodon sanctce helence. 

 Julis sanctce helence. 

 Scarus strigatus. 

 Tetrodon cutaneus. 



The rest may be divided into two divisions ; those which are 

 confined to the Atlantic, and those which occur also in the 

 tropical and subtropical Pacific. 



Species confined to the Atlantic. 



Murcena unicolor. 

 Murcena moringa. 

 Murcena sanctce helence. 

 Holocentrum longipinne. 

 Epinephelis ascensionis. 

 Sargus capensis (also Muscat). 



Garanx dentex. 

 Lichia glauca. 

 Platophrys podas. 

 Scorpcena scrofina. 

 Salarias textilis. 

 Ostracion quadricornis. 



Species common to the Mlantic and Pacific 



Saurus any ops. 

 Priacanthics hoops. 

 Priacanthibs cruentatas. 

 Cossyphus pecloralis. 

 Garanx sanctce helence. 



Garanx ascensionis. 

 Scomber colias. 



Thynnus alcdonga. 

 Thynnus albacora. 

 Thynnus obesus. 

 Gymnosarda alleterata. 

 Thyr sites prometkeus. 

 Balistes buniva. 



In order to ascertain in a general way the affinities of the 

 St. Helena fishes, we may enquire what species that island has 

 in common with the Cape, with the West Indies, and with the 

 Mediterranean. The following lists show which of the species 

 collected by me occur in these several regions. 



Species found also at the Cape 



Epinephelus ascensionis. 

 Priacanthns boops. 

 Sargus capensis. 



Lichia glauca. 

 Scomber colias. 

 Thynnus alalonga. 



Species found also in the Mediterranean. 



Murcena unicolor 

 Garanx dentex. 

 Lichia glauca. 



Scomber colias. 



Thynnus alcdonga. 

 Gymnosarda alleterata. 

 Platophrys podas.
