 etc. I'nt the I'eason why I have kept //. min-iiiordfa and //. argiix 

 sopai-ate and liave ventureil to hurden the ali'eady overstocked 

 uomeucluture by establisliini: the present species is. that oacli of 

 the three species lias veiy characteristic and well-established 

 color-in;irkin^s of its own. It is true tliat one can not place much 

 reliance on mere external luarkings, but in these cases they 

 are so constantly and strikingly different, and so entirely without 

 intermediate gradations, that the tiiree species are distinguislied 

 with ease by tlie Liu-Kin natives and have difli'rent names 

 assigned In' them. Such differences slunild also bi' taken notice 

 of in science, and distinctive names l)e givi'u the species for 

 futiu'e reference. AVhetiu'r the ditlei'cnces are sju'cific or varietal 

 can perhajis only he determined hy a long study on the spot, 

 and even then it may after all turn out to bo a inere matter of 

 fancy whethei' they should l)e assigned s})ecitic oi- vai'ietal values. 

 Koi' the i)resent, I have thought it best to give them sju'cilic 

 values.
