CCLXLII 
Priority of specific names appears to be based entirely upon one section of the 
code of 1867. "That simply says that when a species is transferred from one genus to 
another, the specific name is maintained. "This principle is usually understood and ap- 
plied in the way that the oldest specific name has a right in all cases to be retained, 
It canot fairly be so interpreted and applied, since it governs only to the extent that this 
should be the law, but it is not to be made an ex post facto law. "'lhus when a transfer 
has been made, that ends the matter so far as the choice of a specific name is concerned, 
and no one is authorized to take up a different name. This practice of retaining the 
oldest name under the genus, no matter what older specific names there may be, was adopted 
by Dr. Gray in his later years and by the Kew botanists, for the reason that once esta- 
blished and pretty generally recognized, it would avoid the great mass ofsynonymy, which 
is being heaped like an incubus upon thescience. I must express surprise that Dr. Britton 
has not considered it his duty to publish the last written words of Dr. Gray which were

In hae revisione synonymorum vel generum deficientium nomina specierum 
ad genera singula statu nascenti pertinentia eruenda et nominibus hodiernis 
specierum identificanda sunt; nam generum addenda, modificationes et opiniones 
posteriora non tribuent jus restaurationis nominum justorum lege prioritatis. 
Si nomina generica fungorum imperfeetorum concurrent nominibus fungorum 
perfectorum semper nomina vetustiora lege prioritatis adoptanda sunt, sed nomina 
exanthematium non coneurment.  Verisimile est nomina plura supra enumerata 
in opere Saecardonis esse, sed non exstant in ejus indice universali, qui lacu- 
nosus est ut opus totum.
