Genus AUDOUINIA Quatrefages. 



AUDOUINIA POLYTRICHA Schmarda. 



Cirratulus polytricM Schmabda (1861), p. 58, pi. 27, fig. 214. 

 Audouinia polytrichia Schmarda, Ehlers (1901), p. 266. — Gbavieb (1907), 

 pi. 10. 

 Specimen collected at station D5760, Tinakta Island. 12 fathoms, 

 sand bottom. 



Family TEREBELLIDAE. 

 Genus POLYMNIA Malmgren. 



POLYMNIA CONGRUENS Marenzeller. 



Polymnia congrucns Marenzeller (1884), p. 207 (sep. p. ID, pi. 2, fig. :;. 



A large complete specimen agreeing in character of gills, setae ? 

 and uncini with Marenzeller's specimen, but with tentacles intact, 

 forming a large tangled mass equal to two-thirds the length of the 

 body. Tube also present, composed of Foraminifera shells, etc., 

 adhering to a very fragile membrane. 



Collected at Xasugbu, Luzon Eeef. 



Genus PISTA Malmgren. 



PISTA FASC1ATA Marenzeller. 



Pista fasciata Marenzeller (1884), p. 202 (sop. p. (J), pi. 1, fig. I. 

 Terebella (Phyzelia) fasciata Eheenberg, Gnibe (1869). 



Using the interpretation of P. fasciata as given by Marenzeller 

 (1884) and Mcintosh (1885) one specimen in the collection is re- 

 ferred to this species. As only one branchial process (anterior 

 right) remained attached to the specimen, nothing can be said as to 

 (he comparative size of these organs. The form of the body and the 

 structure of the uncini agreed with the descriptions given by Maren- 

 zeller and Mcintosh. 



Collected at station D5536, Apo Island, 279 fathoms, green mud 

 bottom, temperature 53.5°. 



Genus TEREBELLA Linnaeus. 



TEREBELLA PARVABRANCHIATA Treadwell. 



Terebella parva-branchiata Treadwell (1906)", p. 1175, fig. 71. 

 Using the uncini as diagnostic character, this form is referred to 

 the above species. Although in very poor condition, the specimen 

 possesses three pairs of gills (with manner of branching as in 

 7'. parvabranchiata) , thus verifying TreadwelFs remarks regarding 

 the Hawaiian form. The tentacles were too badly mutilated for 

 description.
