1. Contrary to my expectation, the Asiatic forms of the Comma group are not so near the American as are the European. Dr. Speyer tells us that the former vary from typical Comma in a different direction from the latter. If the American are derived from the European, or the reverse, the Asiatic ought to lie between the two, apparently.

2. I am satisfied that Juba should rank as a species. Dr. Speyer gives sufficient reasons for this, and examination of many examples confirm this view. I have a beautiful variety of Juba (male) sent me by Prof. Snow, and taken by him at Los Vegas, N. M., iu 1882. The upper side is darker—more fuscous and less fulvous—than any other example I have seen, and secondaries beneath and the apical area of primaries are densely dusted with golden-green; the spots white and somewhat smaller than in the type. I call this vat. Viridis.
