Show 860 MR. OLDFIELD THOMAS ON [ Nov. 27, In number 699 1 make the same measurements 4 4 mm. and 8'8 mm. respectively. Lacrymal breadth 3*2 mm. in metero-pygmcrus, 3*7 m ccnncxus. I should not ha-\e the least hesitation in separating the animals on these characters. In addition the palate is wider and the molars larger and less heavily pigmented in No. 699 ; unicuspids longer and lower than in macropygvueus, their proportional sizes about the same. Externally the animals show no special differences, though in the Korean species the feet seem rather heavier, and the colour throughout is a clearer, more greyish brown." With regard to JS. buxtoni, it is said by Dr. Allen to be a member of the S. araneus group, and in any case its locality is so close to that of S. macropygmceus and so far from that of S. cinnexus, that its identity with the latter seems out of the question. It is to be noted that while in No. 699 the upper unicuspid teeth decrease evenly in size backwards, in No. 708 the fourth is distinctly larger than the third, thus furnishing another instance of the instability of the relative sizes of these teeth as a, distinguishing character. 2.
