Gatty Marine hahoraiorij^ St. Andrews. 255 tliere are two much more slender bristles with long, tapering, diaphanous, terminal pieces, apparently larval ventral bristles. The dorsal have the adult structure, being slender, tapering, hair-like, serrated bristles. The dorsal cirrus is much en- larged at the base, but with a slightly tapered tip. Viewed from below the ventral cirrus shows a similar dilatation (ceratophore) at the base and a two-jointed cirrus, a globular papilla occurring some distance inwards. Tiie body, which is marked by transverse lines, termiriates posteriorly at this stage in a broad pygidium. The three pairs of scales of a globular outline are borne on pedicles, the outer edge of each having several large truncate papillse which greatly exceed the proportions in the adult. In the next stages, found on the same date, the snout is truncated and the caudal process has a dimple in the middle. Then the head becomes defined as an oblong mass, rounded in front, and flanked on each side by the tentacular cirri, which are now directed forward. There are still only four bristled feet. The cilia on the scales are larger, and two short broad caudal cirri have appeared under the pygidium. Fijr. Anterior end of young Pholoe, X 100. 4tli February, 1899. The bottom tow-net again procured, on the 4th February, in 5 fathoms, a young Pholoe having thirteen bristled feet on each side. The head bears in front two closely approximated median eyes (fig. I) and two are more widely situated towards.
