796 E. T. NEWTON ON SAUROCEPBALTTS. 



I could, "before Prof. Huxley anoVMr. W. S. Dallas; and both these 

 gentlemen unhesitatingly said the name of Protosjohyrcena, being the 

 earliest, is the one which will undoubtedly have to stand. I have 

 also had a conversation with Prof. Cope. He maintains that Prof. 

 Leidy did not in 1857 sufficiently characterize his genus Protosphy- 

 rcena, and therefore that his name must be ignored, and that of 

 Erisiclithe adopted. Prof. Leidy has given what he considers to be 

 a sufficient reason for separating the English so-called Saurocephalus 

 from the American ones ; and by his reference to the figures and 

 descriptions of Agassiz and Dixon, makes it perfectly clear to what 

 he gives the name of Protospliyrama. This seems to me to be all 

 that the laws of nomenclature demand. His species, Protosphyrama 

 ferox, is also manifestly the type of the genus. I should not be 

 justified, therefore, in altering the synonymy in the above list. 

 The new species of true Saurocephalus, described in the latter part 

 of Mr. Davies's paper, will have to be added to the list, thus : —
