In the Irish examples the inner corner of the third palp-segment is rather well developed, with from 12 to 14 short stout spines, none of which are feathered. Eylais Soari, Piersig. 1899. Zool. Anzeiger, Bd. xxii. p. 67, fig. 8. The type form of this species occurs but rarely ; the preva- lent form found here should, I think, be referred to a distinct race or variety of E. Soari. mstahilis, var. n. My specimens of this variety agree in size with those described by Dr. Piers

Soari. mstahilis, var. n. My specimens of this variety agree in size with those described by Dr. Piersig, ranging from 3 to 4 millim. in length ; yet the eye-plate and palps are uniformly larger, and there are other differences in structure. The eye-plate (figs. 4 and 5) measures from '45 to '48 millim. across, length of capsule about '25 millim., of more Fig. 4. Fisr. robust structure than in the type. Bridge somewhat longer and broader, with the posterior emargination either round or more or less sharply angled. The capitulum measures about *66 millim. from the front margin of the maxillary plate to end of pharynx ; the type of structure greatly resembles that of E. Miilleri: Koenike (Deutschl. Hydrach. pi. xlviii. fig. 153 a). The palps are robustly built, length about 1'20 millim. Inner corner of third segment well developed, with from 14 to 18 short stout spines, the innermost ones weakly feathered. Fourth seg- ment strongly swollen on the inner margin, near which there are about 6 long spines, and the usual group of 4 or 5 strongly feathered spines close to the distal margin. Localities. Common in quarry holes near Crumlin and.
