“EURYPODIUS LATREILLII .

Plate 3, fig. 1a, under view of head, enlarged four diameters; b, exterior view of right hand, ibid.; c, extremity of third pair of legs, ibid.

Valparaiso, Chili.

This species differs from the preceding in having the fingers of the hand without any appearance of a tooth-like prominence on the inner edge, the edges being simply and evenly denticulate. Moreover, the margin of the antennary fossettes behind, is not reflexed adjoining the immoveable basal joint of the outer antennæ.

A specimen an inch in length has the following characters. The beak is about one-fourth the whole length of the carapax; it is flattened above, but the flat surface is placed a little obliquely. The edges are hairy, and in the specimen, the hairs are longer than the breadth of the beak. The second post-orbital spine is prominent and obtuse; the first quite short and obtuse. The carapax has two spines on the medial region, one on the cardiac region, one either side in the same line nearly on the postero-lateral region, and another, forward of this, a little more outward; also one on the middle of posterior margin. The lateral portions of the carapax are somewhat hairy.

The immoveable basal joint of the outer antennæ has no spinous process on outer side, near base, and no distinct tooth just posterior.

The first pair of feet is about as long as the carapax. The others are much longer and more slender. The arm has two small tubercles on the upper side; the next joint a few more; the hand is linear and rather thin, with the upper and under margins hairy. The following legs have the thigh nearly cylindrical, with a few hairs above and below; the fifth joint is longer than the fourth.

The abdomen of the male is narrow, with the last joint subtriannular."
