Report on the Annelids of Puget Sound, Fiji, and Samoa, hy A. L. Treadwell. 



From February 13 to March 4, 1 studied at the Puget Sound station of the 

 University of Washington at Friday Harbor. To Professor T. C. Frye, 

 director of this station, I am greatly indebted for putting its resources at my 

 disposal. The collecting was done in the immediate vicinity of Friday Harbor 

 and at False Bay on the opposite side of the island. What are certainly new 

 species were obtained in the genera Liimhrinereis, Onuphis, Nainereis, and 

 Eteone, and a survey of the literature, as yet uncompleted, may show that 

 others still unidentified are new. An account of these will appear in a later 

 publication. The following notes refer to old species. Aidohjtus varius 

 Treadwell was collected in the sacconereis stage, carrying eggs and larvae, in 

 the herring-trap at the shipyard; Podarke pugettensis Johnson was rare, 

 2 specimens only having been found in Newhall's lagoon; Nereis virens 

 Sars, N. vexillosa Grube, N. procera Ehlers, and N. agassizi Ehlers were 

 common in all the collections, as was Nephthys cceca Fabricius. The com- 

 monest annelid found was Lumhrinereis zonata Johnson, the other Leodicidse 

 found being a new species of Onuphis and of Lumhrinereis, v/ith one specimen 

 of Onuphis (Northia) elegans of Moore. Glycera rugosa Johnson and Hemi- 

 podia horealis Johnson were common, though not very abundant, in all 

 localities. Poly dor a calif or nica Treadwell was abundant in Newhall's Lagoon 

 and in False Bay, and Scolecolepis alaskensis Treadwell occurred in the col- 

 lections. Johnson described two species of Cirratulus — C. cingidatus and 

 C rohustiis. These were rare, but specimens corresponding to both species 

 were found on Turn Island and at Minnesota Reef. For reasons which will 

 be given in a later paper, these do not seem to m.e to be distinct species, and 

 the name cingulatus has precedence. 



Animochores occidentolis Johnson occurred in considerable numbers at 

 False Bay, and I found one specimen on the beach at Brown Island. Of the 

 Terebellids, Lanice heterohranchia Johnson and Thelepus crispus Johnson 

 were both abundant. It is easy to distinguish them in the living condition 

 by the green color of the former and the red color of the latter. Serpida 

 Columbiana Johnson was found in rocks above low-water mark at the station 

 reservation. Two species of Capilella, one being evidently Johnson's C. 

 zonata, were common, and Arenicola claperedii Lev. was very abundant, 

 especially in Newhall's Lagoon and in Boat Bay. Later work was in Suva, 

 Fiji, from April 6 to May 4, and in Pago Pago, Samoa, from May 12 to 

 June 22. In these localities my main study was on the Leodicidse, having 

 in mind a comparison between the Pacific members of this family and those 

 of the West Indian region, which have been the subject of investigations 

 under the auspices of the Carnegie Institution of Washington. Since the 

 literature of the Pacific species v/as not available in the field, I have not 

 attempted the identification of species and their description will appear in a 

 later publication. 



In Fiji, the research was limited to the immediate vicinity of Suva Harbor, 

 the short length of our stay preventing any more extended explorations. In 

 Suva Harbor the reefs on either side of the main entrance and at Rat Passage 

 are relatively rather poor in annelids, but apparently the Leodicidse are better 

 represented than any other single family. The rocks near the outer margin 

 of the reef are channeled by various boring echinoids, and contain many 

 individuals of a rather large Leodice. Other large species were found under
