Genus LAONOME Malmgren. 
Laonome punctata, new species. 
Body rather stout; thorax 3 mm. in diameter. Length of thorax and abdomen, 21 mm. Tentacles 
about 10 mm. long. 
Tentacles about 25 on a side, basal portion for rather more than one-half their length a deep purple 
color. Rest of tentacle in irregularly alternating bands of white, yellow, and 
purple. Inner margin deeply fringed, very short free terminal portion. 
Thoracic somites show great variation in arrangement of metameres. 
Through splitting of somites, the two sides rarely show an equal number of 
intersegmental constrictions, and consequently have an unequal number of 
uncinal rows, the number varying from 5-8. Ventral shields of thorax not 
very prominent, rectangular. A very narrow faecal groove. 
Setse (fig. 76) long, with flattened wing, showing serrated edges. Uncini 
with one large tooth, and numerous finer teeth scattered over the apex of the 
crown (fig. 77). Uncini of thorax and of abdomen similar. 
Body with numerous minute purple spots scattered irregularly over its 
entire surface, forming a dense mass just posterior to the collar. Collar narrow, 
with a prominent incision dorsally and ventrally. 
A prominent spot on posterior ventral face of each parapodium. 
The animal lives in a thick-walled tube, covered on the outside with a layer 
of brown mud. 
Collected at Puata Bay and at Waialea, Oahu. Type no. 5223, U. S. 
National Museum. Length of thorax and abdomen, about 21 mm.; collected at Waialea, Oahu. 
Family SERPUUD^E. 
Genus POMATOCERUS Phillipi. 
Pomatocerus strigiceps Morch. 
Pomatocerus strigiceps Morch, Naturhistorik Tidssehriit, Kj obenhavn, June, 1863, p. 412. McIntosh, Report Chal- 
lenger Expedition, v. XII, p. 520; pi. LV, figs. 3, 4; pi. XXI A, figs. 26, 27, 28. 
Two specimens, somewhat broader than those described by McIntosh, being nearly 6 mm. wide 
in the region of the collar. Each had lost its operculum, the only trace remaining being a short piece 
of the thick, cylindrical stalk. 
Collected at stations 4031 and 4034, 14-28 fathoms, on fine coral sand, foraminifera, corals. 
Genus PROTULA Risso. 
Protula arafurensis? McIntosh. 
Protula arafurensis McIntosh, Report Challenger Exp., vol. xn, p. 511, pi. xxxi A, figs. 17, 18. 
Two specimens. Both were injured, neither retaining any portion of the abdominal region. 
McIntosh’s specimen had lost the branchiae, but in character of thoracic membrane and in setae these 
agree with his description. Branchiae 36-40 on a side, rising from a broad base, tightly coiled. No 
appreciable extent of apex devoid of lateral branches. Length of thorax of larger specimen 7 mm., of 
gills (contracted) 7 mm. 
Fragments of calcareous tubes were found in the bottle with the specimens. It is doubtful whether 
they really belonged to the animal. 
Collected at station 4551, in vicinity of Monterey Bay, California.
