OSTRACION QUADRICORNIS, LINN., subsp. notacanthus, (Blekker.) 

 Ostradon notacanthus, Bleeker, Poiss. Guin^e, 1863, p. -21 (St. Helena); Ned. Tyds. 

 Dierk., ii, p. 298, et alibi. 

 This form, whose relations to 0. quadricornis are discussed above, p. 

 267, p. 270, and p. 280, is recorded only from St. Helena. It will only 

 be entitled to subspecific rank if in future it be shown that the dorsal 

 median spine, sometimes observed in the young, remains persistent in 



the adult.

 Indian Ocean and Archipelago (Giinther). 



I cannot follow Dr. Giinther in accepting for this species the Linnaean 

 name Ostradon gihhosus, since no description of this species was pub- 

 lished by Linnaeus. The first intelligible description was that by 

 Foskaol, and although the indirect references to the figures published 

 by Johnston, Willughby, and others, render it probable that this was 

 the fish referred to by Linnaeus, still there is no way of definitely ascer- 

 taining the meaning. 



"Je crois reconnaitre," wrote Bleeker,* "I'espece actuelle dans les 

 figures citees de Jonston, de Willughby, de Valentyn et de Eenard. 

 Celles de Jonston et de Willughby, copiees sur le meme modele, ne 

 montrent ni Fepine frontale, ni celles de la carene ventrale, mais la 

 grande 6pine dorsale y est assez bien rendus. Celles de Valentyn et 

 de Eenard, quoique grossieres, ne laissent aucun doute pdr rapport ^
