P0LYCHJ3T0US ANNELIDS OE THE HAWAIIAN ISLANDS. 
1175 
Family CIRRATULIDAE. 
Genus CIRRATULUS Lamarck. 
Cirratulus zebuensis McIntosh. 
Cirratulus zebuensis McIntosh, Report Challenger Expedition, vol. xii, p. 384. 
Dorsal bristles smaller and less flattened than ventral and showing a very faint serration toward 
their bases. Ventral more curved and with serrations along greater part of their length. Hooks 
absent anteriorly, present in middle and posterior regions. They are long, slender, and only slightly 
curved. 
Collected at Honolulu Reef and from station 3802, in tow net. 
Cirratulus capensis Schmarda. 
Cirratulus capensis Schmarda, Neue Wirbellose Thiere, I, bd. ii, p. 66, taf. xxvii, fig. 213. McIntosh, Report Ohal- 
. lenger Expedition, vol. xii, p. 383, pi. xxiv A, figs. 9, 10. 
Fragments of much mutilated specimens from Honolulu Reef. In structure of setae they agree 
with the above species. It was impossible to determine anything definite about their other characters. 
Family TEREBELLIDAi. 
Genus TEREBELLA Malmgren. 
Terebella parvabrancbiata, new species. 
Three poorly preserved specimens, to which I have given provisionally the above name. Seven- 
teen notopodia. Dorsal setae broadened and bent at end, apex drawn out into a fine point. Uncinus 
with one very large tooth, apical portion high, showing in profile as many as 6 
smaller teeth (fig. 71). Seen in face view, this apical portion shows a great many 
small teeth, giving it the appearance of a coarse file. 
Tentacles too badly injured for description. 
Gills, one pair; each of a central axis with thick, simple, lateral branches, arising 
alternately on the two sides. Diameter of branches large as compared with the 
central axis, and their bases arise close together. No trace of eyes could be seen. 
Tubes rather thick-walled, of dark brown sand. 
Length, 35 mm. ; width at anterior end, 4 mm. The possession of but one pair of 
gills ought perhaps to put these forms in a new genus. They were so poorly preserved, however, that 
possibly other gills had been lost. 
Collected at station 4028, 444-478 fathoms, on bottom of gray sand and globigerina. 
Type no. 5219, U. S. National Museum; length, 35 mm.

o£ Terebella parva- 
branchiata, new 
species, x 183. 
Terebella (Lanice) flabellum Baird. 
Terebella flabellum Baird, Jour. Linn. Soo. London, vol. vm, p. 167. McIntosh, Report Challenger Expedition, vol. 
xii, p. 446, pi. xlix, fig. 3. 
A single empty tube from station 3938, 148-163 fathoms, on bottom of white sand and broken 
shells. 
Terebella sp. ? 
The collection included one fragment of a Terebella from Pago Pago, Samoa, too much injured for 
identification. 
Terebella crassifilis Grube. 
Terebella ci-assifllis Grube, Annulata Semperiana, p. 226, pi. xii, fig. 2, 1878. 
Some poorly preserved specimens which agree, so far as I can determine, with Grube’ s description 
of this species in every respect except in the character of the thoracic uncini. Grube describes these 
with 4 teeth. In the specimens from Hawaii there are 6. 
Collected at station 3834, on coral rock, sand, and shells, and from station 3876, 28 fathoms, on 
sand and gravel.
