154 General Notes. 



This therefore would not only be its type, but would by elimination re 

 strict Tayassu and DicotyUs to the other species mentioned in the re 

 spective original descriptions of those genera. Dr. Merriam's Olidosus 

 would thus not be required. 



But while Linnaeus's Sus tajacu was the collared Peccary, Fischer's 

 Sus tajassu was, as is clearly shown by the synonymy in his Zoognosia,* 

 the whitelipped species, and that, therefore, must count as the type of 

 Notophorus, and by elimination bring Tayassu on to the true T. tajacu. 

 We should thus have Tayassu, Fisch. 



Subgenus Tayassu, Fisch. (Syn. Dicotyles, Cuv.) Species T. tajacu 

 (type), angulatus, torvus, etc. Subgenus Notophorus, Fisch. (Syn. 

 Olidosus, Merr.) Species T. (JV.) albirostris (type) and T. a. ringens. 



Doctor Allen has taken the same view about the principle of full syno 

 nyms in the case of the Eared Seals, when showingf "that the genus 

 Otoes, Fischer, 1817, is an exact synonym of Otaria Pe"ron, 1816," and 

 so far I fully agree with him. 



But I would venture to ask if the principle on which the name Cal- 

 lorliinus Gray, 1859, is rejected ("preoccupied by CallirMnus, Blanch- 

 ard, 1850 ") is not now an obsolete one, and should we not therefore 

 adopt that name. 



The logical outcome of the non-emendation system, nearly universally 

 adopted in America, and now unreservedly accepted here by myself and 

 others, is that unless two names are entirely alike, the earlier does not 

 preoccupy the later, however closely they may resemble each other. 

 Even if I did not go so far as in the case next following, I should still 

 consider Callorhinus and Callirhinus as " permissible variants " of one 

 compound, and each as valid as Picus and Pica. 



The extreme of this principle is reached in the case of the Leopard 

 Seal, now commonly, but for two reasons erroneously, called Ogmorhinus, 

 (Peters, 1875). 



Firstly, its original and still well-known name was spelt Stenorhinchus 

 on its first publication in 1826,^: and I hold that the name is not invali 

 dated by the StenorJiynchus or Stenorynchus of earlier authors. 



Secondly, it may be pointed out, for the benefit of those who might 

 refuse to accept Stenorhinchus that Peter's Ogmorhinus of 1875, can in 

 no case stand, as the genus had already been renamed Hydrurga by 

 Gistlinl848.|| 



To recapitulate, I consider that the two subgenera of the Peccaries 

 should bear the names of Tayassu, Fisch., and NotopJiorus, Fisch., the 

 Northern Fur Seal that of Callorhinus, Gray, and the Sea Leopard,
