however, no changes affecting nomenclature. Although his twelve new genera 

 in addition to those of Artedi are well founded, I think that they should he 

 regarded as ineligible as occurring in a slightly revised post-Linnaean reprint 

 in which the Linnaean Code is not adopted. The argument of Opinion 13 

 adverse to the acceptance of the names given in the reprint of Catesby applies 

 equally to Browne. 



Valmont de Bomare. — In his recent monograpli of the living sharks 

 (Plagiosfomia, Cambridge, Mass., 1913) Mr. Samuel (jarman has adopted as 

 generic names certain appellations in binomial form, found in Valmont's 

 " Dictionnaire Raisonnee Universelle d'Histoire Naturellc," in four editions, 

 1764-1791. In the first edition the few Latin names are plainly vernaculars. In 

 the " Nouvelle E-dition," 1768, and in " Edition II " in 1775, a few names, all of 

 sharks, assume a distinctly binomial form. It is apparently plain, however, that 

 the author regards these as Latin translations of the vernacular, especially as 

 in his fourth edition (1791), he gives a list of the genera of fishes, including 

 all of those of Linnaeus but adding no names of his own. 



It seems to me a fair ruling that Valmont's names are binomial only by 

 accident, and not accepted as genera by their author. The only new names of 

 Valmont* are the following: 



Galcus = Prioiiacc Cantor 1849 



J'ulpecula = Alopias Rafinesque 1810 



Cntulus (preoccupied) ^ .SV3'///or/i/;fj(i- Blainville 1816 

 Mustellus = Cynias Gill 1903 



(Not Mustelns of Linck, Leach, Fisclier 



or Cuvier, all of tliese based on 



Squalus imistclus L.) 



Discussion. — Opinion 20, issued by the Commission, has <:riven 

 rise to considerable discussion which thus far has not led to definite 

 results. Commissioner Jordan has suggested a middle grotind which 

 will enable the Commission to obtain the results generally desired 

 and without respect to the merits or demerits of Opinion 20. Namely, 

 he proposes that the Commission declare as nomenclatorially invalid 

 the six papers in ichthyology which have produced confusiou imder 

 Opinion 20. 



Commissioner Jordan and the Secretary held prolonged discussion 

 on the matter at Leland Stanford University and they concur in the 

 wisdom of this move.
