Messrs. Berkeley and Broome on British Fungi. 123 



The young individuals differ considerably from the adults by 

 the shorter form of the body, their shorter tubiform muzzle, 

 and by the well-marked development of the teeth, of the scutes 

 of the skin, and of the hooked spines of the scales. There is 

 no doubt that "(7. ve/itom," Pallas, is a nearly adult form, 

 and C. hrevispinis, Kn., Steind., a very young form of C. gra- 

 cilis, and that these two specific names must disappear, as well 

 as the genus Orthichthys of Mr. Gill. His genus Centriscops 

 (type C. humerosus, Eich.) is better founded as regards the 

 physiognomy, but is not based upon any important character or 

 any special peculiarity of organization. 



Finally, in a postscript, I refer to the considerable changes 

 which occur in some groups of marine fishes which I have not 

 had the opportunity of examining in this memoir, but which 

 have been elucidated by other authors, or will be so, I hope, 

 hereafter by myself. I may cite, for example, the metamor- 

 phoses (1) of the Pleuronectidge, which have especially been 

 elucidated by MM. Jap. Steenstrup and Alex. Agassiz ; (2) 

 of certain Gadoids ; the CoucMce, notwithstanding what may 

 have been said, are the young of various species of Motella, 

 and Hypsiptera argentea the young form of a Phycid ; (3) of 

 the Macruri^ Ophidia, and Trachypteri^ which have been 

 elucidated by Mr. Emery ; (4) of the Sunfish {Mola rotunda 

 and Ranzania truncata), of which I hope soon to be able to 

 give an explanation conjointly with M. Steenstrup ; and, 

 lastly, (5) oi Ansonia Cuvieri, Risso {Luvarus imperialist, of 

 which M. Giglioli has demonstrated that Diana semilunata^ 

 Risso {Astrodermus coryphcenoides) , is the young form. This 

 last is certainly one of the most remarkable of the transforma- 

 tions presented by the family of the Scomberoids, otherwise 

 so rich in examples of this kind, to the knowledge of which I 

 have also made some contributions in this memoir.
