Huh. Here I thought the print edition (you do have it?) had some general descriptions and comments on abstracts not available elsewhere. That's why I always bug you.
Second weird note. The web entry on Panthera pardus does indeed specify its source: "Synonyms allocated according to Miththapala et al. (1996)." I have been staring at the Miththapala PDF for a couple of hours today and, nope, saxicolor is not included in nimr but the other way around. By Jove, I think they may have made an error.
