96 MEMOIES OF THE NATIONAL ACADEMY OF SCIENCES. 



Cuvier and Valenciennes sometimes adopted Forster's*, and sometimes (the propensity to 

 claange names still continued) gave new ones, because, for some reason or other, they were not 

 satisfied with any of the old onest. 



Richardsouj: also generally adopted Forster's names§, deviating from this course only in four 

 instances, once in adopting one of Schneider's names||, again in preferring a manuscript name 

 given by Solander to one published by Forsterfl, a tliird time in taking a later name of Lacepede**, 

 and, in another case, deferring to Cuvier and Valenciennestt. 



Giinther generally accepted Forster's names, but in one instance adopted Schneider'sij:!, and for 

 other species took later names. 



The Giintherian nomenclature was adopted by Trof. Hutton and Prof. Hector in the Catalogue . 

 of the Fishes of New Zealand, and the names so adopted are given in the synonymy of the species 

 following. Later, Prof. Hutton revived several of Forster's names previously generally neglected. 



As the conflicting names of Forster and Schneider were necessarily published at the same mo- 

 ment, being each printed for the first time on the same page, neither has the priority, and the 

 name adopted by the first succeeding naturalist may, I think, be justly retained. ' Drs. Jordan 

 and Eigenmann have thought otherwise, and, in the ca,se oi Polyj))- ion, adopted Schneider's name 

 oxygeneios instead of prognathus, but as Drs. Jordan and Gilbert had originally used that name 

 for the " P. cerniiim,^^ the southern species may retain that of P.prognath us later given to it. Drs. 

 Jordan and Gilbert, in another connection (involving tlie question of adoption of Gephalacantlms 

 or DactylopteruSythe former occurring on p. 323 and the latter on p. 325 of the same work), have 

 declared for Ceplmlacanthus instead of the generally adopted Dactylopterus, and enunciated the 

 proposition that " the law of primogeniture applies to twins "§§. This is granted. But what has 

 the law of primogeniture to do with the question at issue? In the case of twins, as the learned 

 doctors well know, one always precedes the other by an appreciable interval of time, but in the 

 case of two names first printed on the same signature, the publication of the two is necessarily 

 shmiltaneous, and no question of primogeniture can arise. Under the present circumstances, 

 then, the adoption of one or the other name is open to the next naturalist who has to deal with 

 the species, and I shall follow him. My own preference would be to adopt Forster's names, as he 

 was the original investigator and generally his names were more apt, but, it seems to me, the 

 name to be used was fixed by the action of the first user.
