INTRODUCTION. 
The polychsetous annelids here described were collected by the U. S. Fish 
Commission steamer Albatross , in 1902, in the vicinity of the Hawaiian Islands. In 
addition, a single specimen ( Terebella sp.) from Pago-Pago, Samoa, and a number of 
specimens collected in 1903 off the coast of California are described in this report. 
The families represented and the number of new and old species found in each are 
as shown in the accompanying table:

Much of this material was very badly preserved, and it was often difficult to get 
normal structures for study. It is probable, therefore, that some species here 
described as new may belong really to previously known species. My chief endeavor 
has been to describe them with clearness, so that the}" may be recognized if they 
appear in later collections. 
Family SYLUD£. 
Genus TRYPANOSYLLIS. 
Trypanosyllis gemmipara ( P) Johnson. 
Trypanosyllis gemmipara Johnson, The Polychaeta of the Puget Sound Region, Proc. Boston Soe. Nat. Hist., vol. 
29, no. 18, p. 405, pi. 7, figs. 72 to 76. 
Fragments of three specimens, probably of this species. Setse have rather longer terminal joints 
than in Johnson’s description, and the esophagus is shorter. Esophagus with 8 rather than 10 teeth. 
Collected at station 4070, 45 to 52 fathoms, on a bottom of fine gray sand, and from station 
4551, in the vicinity of Monterey Bay, Cal.
